What is Roof Decking?

Roof decking is installed on the roof system to serve as a platform for other components, such as insulation and waterproof membranes. In addition to providing a platform for later installation of other materials, roof decking also provides an aesthetically pleasing surface for the roof system and is often left exposed in order to maintain a clean appearance. Roof decking can be installed over an existing roof deck or underlay, or it can be installed independently of any other materials in order to provide a level surface with which to work when building a new roof system. There are many kinds of roof deck, each designed to meet a variety of needs and requirements based mainly on the application. For instance, some roof replacement materials might be thinner or thicker, while others might be reflective or absorbent. To install a new roof decking you need to consider the weight of the air conditioning equipment and the frequency of rain and snow. When you know about roof decking materials you will be able to determine the new roofing materials and the roofing contractor to employ. ## Is roof decking waterproof? You do not want to have damaged roof decking with costly repairs for your house. Roof decking is generally designed to be moisture-resistant and provide a weatherproof seal for other building materials. Many homeowners work with a professional roofer from a reputable roofing company to install waterproofing layers. They use an excellent decking material for the roofing system to ensure structural integrity. This might mean that the roof decking itself can withstand exposure to moisture, or it might only serve as a protective layer over another material such as plywood, [composite materials](/guides/deck-builders/what-is-composite-decking) or oriented strand board (OSB). ## What materials are used for roof decking? Before purchasing your roof's decking consult a roofing contractor who will ensure your roofing system has sufficient support and meets dimensional stability. The roof sheathing should be free from excess moisture, crack lines and water damage. It needs to be properly conditioned with light passing to ensure moisture equilibrium. The roofing shingles should also have fire protection. New roof decking materials, such as [choice of wood](/guides/deck-builders/what-wood-to-use-for-decking), vary according to the type of roof they will be used for, and their respective applications. Some common examples of roofing materials include: - Plywood - Oriented strand board - Timbers such as pine or cedar - Reflective or aluminium materials - Wooden beams ## What are the main benefits of roof decking? Roof decking provides the surface on which other roof components are installed. It is beneficial to know about roof decking because it creates a level, solid foundation for shingle installation. Without this new roof foundation, shingles might shift or not have the support they need to be installed correctly. In addition, having an exposed roof face allows for easier cleaning of roof-bound materials such as moss or lichen. If these plants grow over exterior building material, they contribute to leaks and deterioration of your roof system by depriving tiles of necessary support. Having a clean surface with good drainage is important for avoiding these problems. ## What are some common mistakes made when installing roof decking? A common mistake made during roof replacement is underestimating how much space tiling requires. A roofing material like tiles requires enough room to move around on the surface. If that space is not allowed or provided by improper installation, then tiles might crack during installation or settlement. This can lead to other problems with your roof system over time and you will need a roofing contractor to help. During roof repairs, the roof decking sometimes gets installed too low, which leads to leaks during heavy rains. Also, make sure that any nails are at least 2" away from the edge of the wood. Damaged roof decking can puncture fragile materials underneath the roof replacement area. ## What is the purpose of a roof deck? The roof deck is the surface on which shingles are attached. If your roof sheathing is not strong enough, or if your [wood is not treated](/guides/deck-cleaning/what-is-the-best-decking-oil), the roof wood boards will last less than five years. The following structural components are vital: - When you build a house you need to install new roof decking plywood over the blocking. This strengthens the floor for heavy loads like appliances and cabinets. The same thing applies to the roof. - Oriented strand board (OSB) or oriented stand board (OSBP), made with wood strands glued at an angle of 0degrees/90degrees forms an interlocking matrix that resists sagging. - Fibreboard is made of small pieces of wood chips pressed together under heat and pressure to form a solid layer. It's more expensive but it provides better protection from fire because it doesn't burn as easily. - Timbers such as pine or cedar, work best on a roofing structure if they're thick and allowed to dry for six months before installation. - Reflective or aluminium materials reflect sunlight and help keep roofs cooler. Roofing materials like wooden beams should be pressure treated with an anti-rot solution at the mill before you buy them. Most lumber yards can do this, but it's not a bad idea to paint the ends of the beams to slow down moisture absorption by keeping them out of direct contact with wood and concrete. It's also wise to install plywood panels over joists in your attic so that weight on the roofing shingles is evenly distributed across roof decks. This prevents sagging and makes for a safer roof system overall - If you don't want problems later on then you have to go with strong decking material. If you use plywood, OSB or OSBP you should know that these materials are rated in accordance with their structural load. ## How do I know if my roof deck needs replacing? You will need to seek roofing contractors if you need your roof replaced. The following are signs that your roof deck is in bad shape and needs a new roof deck includes: - Moisture or water leaks into the house - Cracked or popping tiles - Curled, cracked or missing shingles - Tiles lifting off the roof surface - Leaky roof - Sagging ceiling ## What is the difference between a rooftop and roof deck? The difference between a rooftop and a roof deck is the location where the deck panels is positioned. A regular roof's decking has a flat surface called a 'roof top', which acts as the foundation for the installation of the shingles. The other type of roof has an exposed surface, or what we call the 'roof deck'. This exposed roof deck acts as a base on which other materials can be placed. ## What is the difference between floor decking and roof decking? The basic difference between floor decking and roof decking is the purpose they serve. Floor decking refers to a platform or surface on which some other material can be laid, like tiles for example. It strengthens the entire structure by distributing the weight of the tiling evenly. But roof decking is something different and uses new decking material. It provides support for asphalt shingles roofs. This means that your shingles will not last as long if you don't use stronger or other roofing materials to build your roof decks for residential buildings. ## What are different kinds of roof decks? The roofs that have an exposed surface are roof decks. This means they don't have the protection of a rooftop, so it's essential to use stronger material in building them. Some of the most common materials used for roof decks are plywood, OSB, fibreboard and concrete decking. [Woods like Merbau](/guides/deck-builders/what-is-merbau-decking) are best left for aesthetic applications. Do not confuse these materials with shingles or tiles because these two things can be laid on top of them. ## Tips for cleaning your roof deck area After you've built your roof deck, it's a good idea to paint the edges and ends of the beams with an anti-rot solution. Most homeowners do not know that this will retard moisture absorption and prevent water damage by extending the life of your roof. Make sure all shingles and tiles used in your roof match. If they don't, you could end up paying more for home improvement repairs later on. If there are any exposed beams such as those around skylights, make sure there is no plywood or OSB over them. These types of roof decking materials do not protect against water leaks because water gets absorbed into them. It doesn't matter what kind of material you use to build your roof decks, just make sure that whatever material that is used has been treated with an anti-rot solution. It's also important that you use strong material for your roof decks because this is where the bulk of your roof's weight is placed. Once these things are done, it won't matter what kind of tiles or new shingles you install on top of them. Find out more about roof tiling, and who can do it, from the [New South Wales Department of Fair Trading](https://www.fairtrading.nsw.gov.au/trades-and-businesses/licensing-and-qualifications/roof-tiling).

What Wood To Use For Decking?

If you want to save money on your decking installation then consider using recycled wooden slab. The best wood for decking is naturally rot-resistant. Remember, it's going to be exposed to heat and UV rays all day long every day, so you want something that won't break down too quickly under those conditions. Here are some options: Cedar hardwoods are generally considered one of the most durable decking materials on the market, lasting up to 30 years without any treatment or refinishing. Cedars are available in several colours as well which can enhance your landscape design. Western red cedar is an excellent decking material if you're looking for something naturally resistant to decay, insects, and moisture. These features make western red cedar decking a very popular choice among homeowners who live near saltwater. Cypress is a natural beauty and has a natural resistance to decay and insect infestation making it particularly suitable for extreme weather environments like coastal areas. The heartwood of cypress is naturally resilient to harsh elements such as chlorine, saltwater, and other environmental pollutants. It is also used extensively in caskets due to its ability to last for decades without decay. [Merbau decks](/guides/deck-builders/what-is-merbau-decking) are very popular. Redwood hardwood is one of the most popular tropical hardwoods used as a decking material because it's naturally resistant to rot and insect infestation. It also has excellent durability in sub-zero temperatures making it perfect for climates that experience heavy snowfall or high winds. ## Can you use normal timber for decking? Generally speaking, you can use either hardwood decking or composite decking. However, it depends on the resources available and what you intend to achieve. Remember, you're going to be exposing your deck to harsh elements like heat and UV rays all day long every day which means that the type of wood that you choose is very important. Generally speaking the best woods for decking materials include cedar, redwood, cypress, and Douglas fir. ## What finishes can I put on my deck? You have two choices when it comes to finishing your deck: [stain or paint](/guides/deck-cleaning/what-is-the-best-decking-oil). If you go with a paint option ensure that it has an acrylic base otherwise it will peel away in just a few years under the suns rays. On the other hand, if you want something natural looking then you should consider a stained deck. Stain has the advantage of allowing the grain of your wood to show through; however, it will need regular upkeep. ## What is involved in building a deck? There are a number of steps involved in the construction of a deck. The first step is to mark out the outline of your proposed deck on your land. You should ensure that there is enough room for you to move around freely during its construction, otherwise, you will need to shift some things about before it can be built. Next, you'll need to lay down a bed of gravel. This provides a perfectly level foundation for your deck and ensures optimal drainage which prevents the wood from rotting prematurely. If you prefer not to have a landscaped area surrounding your deck then this would also be an excellent time to set up retaining walls if necessary. And last but not least, lay down wooden beams throughout the frame which will provide additional support for the final installation of your deck. These are just a few of the steps involved in building a deck. Remember, there are many different ways to go about this so if you're unsure of how to begin then consult with your local home improvement specialist to ensure that you have all the necessary materials before starting construction. ## Which timber to use for decking? Trees that have hardwood are generally used for decking, especially cedar and redwood. These types of trees do not get damaged easily by insects or rot away under the rain, heat or sun. Other woods such as pine can also be used but will need to be treated with chemicals or waterproof materials before being installed on a deck. If you want to save money on your decking installation then consider using recycled wooden slabs from old homes instead of buying new pieces of lumber. ## Where to use different types of lumber When you are planning to buy the lumbers for your decking, it is important that you know what type of hardwood is suitable for which environment. When considering the types of decking, you should inquire about how much maintenance is required for outdoor use. An incorrect choice can give problems in the future, maybe sooner than expected. Listed below are some of the timbers used for different purposes, their characteristics and where they should be used. ### Cedar One of the expensive hardwoods that have a pleasant smell and is stable underwater, so it should be used on any place along the coast or around swimming pools or ponds. The hardwood is resistant to moisture but not rot-proof if not chemically treated. It will sustain well if you use a specifically formulated treatment every year before winter with oil-based preservative paint. ### Redwood Both redwood and cedar are Australian hardwoods. But the B grade redwood is very durable against water and insects. The pressure-treated wood is also resistant to rust and does not split or warp even in high humidity or rain and requires annual power washing. The real wood has a high density, so it will withstand the weather conditions making it maintenance-free. ### Cypress Cypress decking is well-suited for a new deck. When pressure treated, it is resistant to water damage but not rot-proof. Regular maintenance by applying preservatives before winter can sustain for many years without any replacement. Pressure-treated lumber is durable and helps to prevent rot and insects species. You can also consider composite decking during construction common to a different wood. ### Yellow pine This hardwood is good for low tone interior flooring, used as a beam under the deck because of its average durability. Treated pine decks have a high resistance to scratch and abrasion, making them great for heavy-duty applications such as flooring, furniture legs, and posts ## Blackbutt Blackbutt is another dense hardwood decking that can be used on decks or low tone interior floors; does not need regular treatment, though protection from the water will increase its lifespan considerably. ## How long do timber decks last? There is a saying that decking timbers last as long as their weakest component. If the decking boards are replaced after 5-6 years, then that might be the answer. The life of decks can be increased considerably if treated with good quality preservative paints every year before winter in an appropriate manner. There will come a time when you have to replace some components, but if proper care has been taken all through the life of your deck then you will feel satisfied when it comes time for replacement or repairs. If you are building a deck you may need to meet local regulations and approvals, such as those explained by the [City of Gold Coast](https://www.goldcoast.qld.gov.au/Planning-building/Building-applications/Domestic-building-works/Do-your-building-works-need-approval). Check to see if regulations apply in your local area.

What is the Best Decking Oil?

Both decking oil and stains are similar and the best way to protect your new deck\ against any weather damage. Recommending the best decking oils is a difficult question to answer as it depends on what you are looking for. For example, if you want the best-looking deck then a quality wood stain might be best. But if you want something that protects and lasts longer then a quality spar varnish may be the way to go. Stains are water-based, which means they can be applied in direct sunlight. They will protect against the elements while enhancing the wood grain. Stains have a low sheen or semi-gloss look, so it won't be as shiny on the wet wood once applied. Usually, one coating is sufficient for good coverage, but two will give it a more natural colour. It will need to be scrubbed with clean water when dry to remove any residue or bits of dirt that might still be sticking around. ## Is stain or decking oil better? Both decking oil and stains are pretty similar, they are the only way to protect your new decks against any weather damage. If you want something more perfect finish then staining would be the way to go. Staining is also popular because it doesn't need as much maintenance work as varnishing does. You can do a great job by applying stain basically immediately after sanding or replacing boards on your deck. It also has a short drying time. If you don't mind spending a bit extra money then some good quality spar varnish may be perfect for you. It makes your deck look natural, shiny and glossy while protecting it from rotting caused by water sitting on top of the wood. Spar varnishes offer oil-based treatment, so they need to be applied in a well-ventilated room to reduce its drying time. One of the drawbacks to varnishing is that it sometimes doesn't last as long compared to stains, and you have to apply a second coat for maximum protection. If you want a glossy or semi-gloss finish then varnish might be your best choice. ## What is the best decking oil to use on Merbau? A quality spar varnish may be [perfect for a Merbau deck](/guides/deck-builders/what-is-merbau-decking). It is best to allow the timber to let its natural tannin flourish before oiling every square metre to cover a spotted gum deck. For a new spotted gum decking you need to select the best decking oil to suit your paint. It is essential for protection and makes your timber deck look shiny and glossy while offering UV protection for quick drying to prevent it from rotting caused by water sitting on top of the wood. Natural spar varnishes are for oiling your deck, so they need to be applied on the decking surface to enhance maintenance and protection. One of the drawbacks to varnishing is that it sometimes doesn't last as long compared to stains, and you have to apply a second coat for better coverage. If you want a glossy or semi-gloss finish then varnish might be your best choice. ## What is the best way to apply decking oil? Before you even begin oiling your deck it's important to ensure the surface is free from grease, dirt, or dust. For oil-based treatments, you need to use a garden hose and clean water to wash down your deck after sanding it back. Once the surface is no longer sticky you can move on to applying the oil treatment. A brush is usually sufficient for most DIY applications to prevent the application of excess oil. But you may need a roller if your [timber decking surface](/guides/deck-builders/what-wood-to-use-for-decking) is large or requires a second coat of oil. Lightly tinted oil works best when applied in thin, even layers so try not to be too heavy-handed handling timber oil. It will take at least 12 hours before the first timber deck coat is completely dry, so make sure there are no plans for major foot traffic near your deck during that time. ## What does decking oil do? Timber decking oil works by penetrating the wood, protecting it from the elements. Once fully dry (usually after 12 hours) it forms a waterproof barrier around your deck that's resistant to ultraviolet light and offers maximum protection. It also increases the life of your boards by making them more repellent against harsh weather conditions. ## How do I treat a deck? The exact process used for treating your decks will vary depending on the type of timber decking you're using. So consult with a professional before you apply a cheap oil that can peel after oiling. They will recommend the best decking oil or products if you're not sure about which one to buy for the furniture. Oil-based products are usually more expensive than water-based but they provide a better quality result even when oiling your house. Water-based products aren't as durable as oiling your deck and require more effort on your part to clean up after. If you want something that looks more natural, to maybe [suit an Ipe deck](/guides/deck-builders/what-is-ipe-decking), then oil treatment may be for you, but if you want something durable then natural oils might be perfect. ## What is the easiest way to maintain my deck? The faster your decking oils dry after applying the first coat, the lower chance of it smearing or sticking together. Most non-water based oils will take around 12 hours to dry completely, so make sure there are no plans for major foot traffic near your deck during that time. Clear wood paint for timbers are very popular, but if you'd prefer something a little more traditional and weather-resistant then oil-based products will give you a great result. You can get them in a variety of colours and they're all safe for use. The best decking oil also protects the wood against ultraviolet radiation and rot. Ordinary timber oil tends to lose intensity quicker compared to timber oil-based products, so you may have to apply more deck coats after a few months. This also works well with [composite decking materials](/guides/deck-builders/what-is-composite-decking). ## What is the best way to protect my deck from rot? Ordinary stains tend to lose their intensity quicker compared to oil-based products, so you may have to apply more coats as time goes on. Using a fresh coat every few years will also help extend the life of your boards and provide a nicer result too. When applying a new coat always use thinner layers first - this reduces the chance of peeling or smearing. If you're planning on using an ordinary household brush make sure it's not worn down from other jobs because it might cause uneven coverage. Oil works by penetrating the wood, protecting it from ultraviolet light, and preventing rot. Once fully dry (usually after 12 hours) it forms a waterproof barrier around your deck that's resistant to water damage. You can also apply more than one coat of oil for extra durability if you like. Oil-based products are usually more expensive but they provide a better quality result, so if you want something that will look natural then it may be right for you. ## What is the best way to protect my deck? Water-based stains tend to wear quicker compared with oil-based finishes and remove easily with ordinary household chemicals such as bleach. Cleaning up spills and stains can be difficult because they don't soak into the surface as oil does; instead, you'll need to apply more coats if you want something that will provide good coverage. The oil penetrates the wood, protecting it from the elements and preventing rot. Once fully dry (usually after 12 hours) it forms a waterproof barrier around your deck that's resistant to ultraviolet light and water damage, including bleach. It also increases the life of your boards by making them more water repellent. If you're planning on using an ordinary household brush make sure it's not worn down from other jobs because it might cause uneven coverage. The process for applying oil depends on what surface you're coating so check with a professional beforehand if unsure. Water-based stains are usually less durable than oil-based products but they do come in many different colours.

What is Ipe Decking?

Ipe or Brazilian Walnut as it is more widely known, is a dense and naturally durable Brazilian hardwood. It is also native in South America where it is used together with pressure-treated pine. Ipe deck durability makes it ideal for use as decking material. Its natural oils have a long-term weather-resistant effect, making them ideal for use in exterior applications. Ipe's natural oils also provide slip resistance, making it an ideal [exterior decking material](/guides/deck-builders/what-wood-to-use-for-decking). It has the same fire rating as concrete preventing it from floating in water due to its density. The extreme hardness and pressure-treated lumber keep the material resistant to wear and extremely resistant to damage from impact, which causes less maintenance of staining or painting of the deck project. Ipe is extremely dense and naturally repels termites and other insects that feed on wood fibre. One more benefit is its deck finish anti-fungal nature can help prevent rot in areas where there is high humidity. The dense quality of Ipe keeps the spaces between the fibres packed tightly together thus preventing moisture penetration. ## How do you prepare Ipe decking for painting? Ipe can be painted with any standard exterior paint. Bleach-based cleaners are not recommended as the bleach will weaken the wood fibres of the Ipe deck over time and break down the oil finish. ## How do you maintain Ipe decking? Maintaining your ipe deck is simple. The decking materials can be cleaned with soap and water to remove dirt, debris, or light stains. The tropical hardwood has natural oils that will repel moisture, but in some applications, it may be necessary to apply Ipe decks [with an oil finish](/guides/deck-cleaning/what-is-the-best-decking-oil). Since it is hardwood lumber it is best to oil it only once yearly for the maintenance of its natural colour. ## What oils should I use on Ipe decking? Penetrating oil treatment is recommended for Ipe decking boards maintenance. Some suggested oils include the below. ### Penetrating oils These oils penetrate deep into the wood's pores and harden there, creating a water repellent surface on the finished deck. ### Semi-permanent oils This oil does not penetrate as deeply or as long as a penetrating oil finish would on the new deck. ### Full-film lubricants These oils have no penetration properties at all. They leave behind a "greasy" shiny sheen due to natural resistance. ## Is it necessary to use exterior grade paint on Ipe decking? Yes, you must use the highest quality exterior grade paints specifically designed for painting ipe decking so the finish can hold up under harsh weather conditions. Standard interior paints are not meant for high traffic areas, let alone exterior conditions with high moisture content. ## Are there any other warnings for working with ipe decking? Yes, wood dust, any wood dust, can be very dangerous if exposed over a long time period. Take care when working with or around any form of lumber that includes ipe decking and any hardwood decking. Always use the proper safety equipment such as a respirator mask (to prevent inhalation of harmful chemicals such as wood dust), ear protection (to prevent damage to your hearing from loud power tools) and gloves (to protect hands against rough splinters and blisters). ## What is the best way to cut ipe decking? Ipe can be cut in much the same way as other types of hardwood. The best type of saw to use is a circular saw with a sharp blade installed. More ipe can also be cut using electric saw blades or hand saw. ## What are the most common applications for ipe decking? The most popular application for ipe decking is in outdoor patio flooring, both residential and commercial. Real ipe durability makes it ideal for exterior conditions such as patio, pool deck, balconies, and walkways. Ipe is also used as exterior siding and trim. Applying sealer to fresh cuts also prevents most woods from splitting. ## What are the most common colours of ipe decking? The natural beauty colour of ipe is brown to dark brown with the red and amber hues tone, but it can be stained into most board colours imaginable and is common in the below. - Natural brown. - Dark walnut. - Mahogany (often mixed with redwood and tigerwood). - Teak (tan and grey). - Cherry (red and black). ## Can I pressure wash an ipe deck? No unlike many pressure-treated woods, power washing is not ideal for an ipe deck stain. Using high-pressure water on the best decking material will damage the Brazilian hardwoods by forcing water deep into the grain. Also, the Ipe composite deck should only be washed with soapy water. Proper washing involves using a soft bristle brush to loosen dirt and debris. You may also power wash the composite boards adjacent to ipe, but watch for over-spray on your decking surface. ## Is it possible to sand off an old finish from ipe decking? Yes, but once you go through the first layer of wood, no finishing product will hold up under weather conditions afterward. The best way to refinish ipe composite decking is to use a penetrating oil finish or semi-permanent oil for quick touchups that require frequent maintenance. ## How do you clean mould off an ipe deck? For light mould stains, try 1 part bleach to 10 parts water. Spray the surface and let it soak for several minutes before cleaning with fresh water. If you have stubborn mould stains that refuse to go away, try using oxalic acid or potassium permanganate as a last resort. You can find these chemicals at your local hardware store. Always follow the manufacturer's application instructions and take all appropriate safety precautions when working with any type of chemical cleaner on decking materials such as rubber gloves, safety goggles and respirator masks (if handling chemicals). ## How do I oil an ipe deck? Ipe decking exceeds codes for various constructions for the static coefficient in an area with high moisture level. You may apply an oil finish such as linseed oil or tung oil to ipe composite decking per square foot. Oiling is not necessary for the life of your wooden outdoor floor, but it will help to protect against moisture and UV rays. You can also consider using a penetrating oil finish if you wish to avoid the greasy sheen left behind by traditional oil finishes. If applying an oil finish, use a clean cloth or lint-free paper towel. Wipe a thin layer onto the surface and allow it to sit undisturbed for several hours before wiping off excess with a dry cloth in the same direction as the wood grain. Repeat this process every 3 months or more frequently depending on weather conditions. ## How do you stain Ipe decking? You may use a waterproof exterior wood stain to give your Ipe decking material new life or to enhance its natural colour. You can also use an oil-based semi-transparent stain instead of applying a solid, opaque stain. A transparent finish will allow some of the wood grain and texture to show through. If you decide on a semi-transparent finish, only apply one coat as multiple coats might become difficult to remove later. Make sure that the surface is clean and dry before starting this project and wear rubber gloves, safety goggles, and a respirator mask for protection against harsh chemicals. ## Is Ipe wood real wood? Yes. Ipe decking is real wood and belongs to the same family as teak and mahogany. The only difference between Ipe and other types of hardwood decking is that it doesn't require as much maintenance as most tropical hardwoods. It is also aesthetically pleasing and it lasts for a long time. It is a great [alternative to Merbau](/guides/deck-builders/what-is-merbau-decking). ## Is ipe decking worth the cost? Yes, even though it is more expensive than cedar, ipe is worth the cost. Ipe wood is naturally resistant to rot, decay, termites, and other types of insects making it an environmentally friendly choice for outdoor flooring. Its acclimation process begins only if you move it to a different environment. It's also durable. An ipe deck can last up to 35 years with minimal care depending on the owners, which is two times longer than most tropical hardwoods. Ipe wood offers a natural non-slip surface that won't crack or splinter under weather conditions. It looks beautiful when oiled or sealed and isn't easily damaged by foot traffic like composite materials are. It's also easy to clean, which makes it ideal for high-traffic areas where kids play all day long. There are various local government regulations when install a deck. [Tweed Shire Council](https://www.tweed.nsw.gov.au/development-business/building-renovating/home-renovations-do-I-need-approval/balconies-decks) has a great guide, but check with your local council.

What is Merbau Decking?

Merbau decking is a quick-growing, lightweight wood with a minimum environmental impact. It works well with all types of tools and stains well. In addition, it resists warping and holds nails more securely than most other woods used for decks. If you are planning on building a new deck or replacing some planks in your current timber deck, Merbau could be the perfect choice of material for your new project. Merbau wood has many great features that make it attractive as a potential [deck building material](/guides/deck-builders/what-wood-to-use-for-decking). It's a strong, easy to use wood that is less likely to warp than woods commonly used for decks. It requires minimal maintenance, and it can be stained to closely resemble other types of wood. It is resistant to moisture and can withstand high temperatures well, making it suitable for many climates. Its low density also makes it easier on the back when working with large boards. ## Is Merbau good for decking? Merbau makes an excellent material for timber decking or timber flooring because of the greater usability, workability and durability of this timber species. It's harder than popular types of wood used for decks, like pine and cedar, but it doesn't have the higher price tag that redwood has. Merbau is characterised by its straight grain pattern and medium texture. It works well with all tools, but especially so with nail guns since nails go in easily and hold firmly. Without proper care, Merbau can become greyish over time when exposed to sunlight, therefore it's important to use a [high-quality sealant or oil](/guides/deck-cleaning/what-is-the-best-decking-oil) on your finished Merbau deck to protect the natural colour of the wood giving it a beautiful appearance. ## Is Merbau a hardwood? Merbau is a hardwood, which means it's derived from broad-leaf trees. It's closely related to American cypress but has some key differences in appearance and uses. While they're both lightweight woods that are used for decks, Merbau is slightly redder in colour than cypress and can be more durable timber decking because it absorbs less water than its cousin. ## What kind of maintenance does Merbau need? Although Merbau timber doesn't require much maintenance, you should always use a high-quality sealant on this type of wood so the natural colour stays true over time. A premium exterior oil or natural oils or water-based oil work well to keep your finished project looking its best for years to come. If you were planning on staining the deck instead of sealing it, you should choose a product designed for use on the natural beauty of Merbau wood which requires minimum maintenance. ## How is Merbau treated? Merbau can be treated with either an exterior oil or a penetrating stain. However, if you plan on staining the deck instead of sealing it, make sure to choose a treatment appropriate for Merbau wood. Always follow the manufacturer's instructions carefully when applying any type of treatment to your decking material, since incorrect application could void its warranty. ## How long will Merbau decking last? If you take proper care of your Merbau decking, it could last for decades, same as [composite decking](/guides/deck-builders/what-is-composite-decking). However, even the most durable of woods will start to show signs of wear if not properly maintained. Regular cleaning with a high-quality soap or detergent will go a long way in keeping your wood looking its best year after year, and sealing it on an annual basis will help keep its natural colour intact over time. ## Advantages of Merbau decking - Fantastic colour - Will not split - Has a medium texture - Resistant to decay and mould - Resistant to damage from insects - Difficult to dent or scratch - Requires very little maintenance ## Disadvantages of Merbau decking There are a few negatives behind using this great looking wood. ### Price It's expensive wood. Expect to pay a bit more for Merbau lumber/planks. However, if you want a long-lasting deck that will look great year after year, then Merbau is well worth the investment. ### Seasoned boards are grey Because Merbau is naturally resistant to decay, make sure to offer any untreated boards some extra protection before using them on your finished project. Otherwise, they may turn out more grey than you'd like. ### Low shock resistance While Merbau is naturally resistant to insect damage, it's not particularly resistant to physical damage. Take care when using power tools on this wood. ### Limited supply If you're building a deck or another project that requires lots of Merbau lumber such as outdoor decking, composite decking, or performing maintenance procedures, make sure to plan ahead so you don't run short before your job is finished. ## What are the natural colours of Merbau? Merbau lumber is naturally a lighter, coppery-brown colour that darkens as it ages. However, if you want to keep your wood looking its best for as long as possible you should always apply a high-quality exterior oil or natural penetrating stain to the surface so it doesn't fade over time. ## Can you leave Merbau decking untreated? You can leave Merbau untreated. However, the natural colour of this wood is a coppery brown that will darken considerably over time. To avoid this change in colour on your deck or any other project made from Merbau lumber, make sure to protect it with a high-quality exterior oil or penetrating stain before using it on your final product. ## Should you treat Merbau? Yes. You should always protect Merbau with an exterior oil or penetrating stain to ensure it lasts as long as possible, whether for use in decks, outdoor furniture, timber flooring or other applications. Water often causes this wood to expand and shrink, which can cause splitting over time if precautions are not taken. ## Is Merbau sustainable? Merbau is a sustainable wood harvested in accordance with various standards for sustainability. This ensures that products certified as sustainably sourced are obtained from forests that meet strict environmental, economic and social criteria, including good management of resources to maintain biological diversity and encourage the conservation of soil, water and wildlife. ## Where does Merbau originate? Merbau comes from Southeast Asia, mostly Malaysia and Indonesia, but is also grown in Papua New Guinea, Australia, Central America and South America. It's not grown commercially in the US or Canada. Merbau trees grow quickly, so this timber can be replaced on a continuous basis without compromising the growth of new trees. Thinking of building a new deck? Tweed Shire Council has a great guide to [building a deck](https://www.tweed.nsw.gov.au/development-business/building-renovating/home-renovations-do-I-need-approval/balconies-decks) on your property, however you need to check your local requirements. ## How long does Merbau decking last? As a naturally resistant hardwood, Merbau will last for decades if it is properly maintained. This means keeping it oiled or penetrating-stained on an annual basis. Doing so will ensure that the wood does not fade over time and that it holds up against the elements as long as possible. ## What is the difference between Merbau and other hardwoods? Merbau is a prefinished hardwood that contains an oil that helps to protect it from rot and insects. It's suitable for all climates but is especially durable in humid or coastal locations. Other hardwoods are made by combining plywood with lots of chemicals and different types of woods. It can be difficult to keep these types of decks protected over time.

What is Composite Decking?

Composite decking is created out of recycled wood and plastic. It looks like real lumber but it won't rot, warp, crack or splinter. Composite decking can be made to mimic the look of other types of materials such as brick, rock or stone from the same basic category. It's generally low-maintenance and easy to clean. Composite decking boards are manufactured using a traditional pressure or high-pressure mould to form the individual pieces. They are typically not formed in long planks like traditional lumber; instead, they are formed into square or rectangular shapes with rounded corners for easier handling. Once they have been moulded together several boards will be placed side by side until enough length has been achieved to complete the installation. The boards are then sheared down to the correct width and routed on the top and bottom for a smooth, splinter-free finish. The boards are then sanded along their length to remove any variations in colour from the manufacturing process. They are also sanded on their top and bottom faces to make them suitable for use as outdoor decking. The first step is to measure off your deck area making sure that it is large enough to accommodate all of your furniture as well as leaving room to walk around comfortably. Once you have measured your wood decking boards, you can begin assembling them together side by side until they reach one full direction of your deck. You will need a power drill with screwdriver bits or a screw gun depending on whether you choose screws or nails to hold these pieces together. Prior to assembling the boards together, you will need to add a plastic or rubber sealant strip along the edge of each composite decking board so that it adheres properly and snugly with the next board in line. To install these pieces, just use your screwdriver bits and drill them into the ends of every other wood decking board while they lay side-by-side on top of one another. You should also apply caulking between every joint and into any exposed ends and cracks about an inch deep for maximum waterproofing capabilities. Once you have done all this, you will then be able to stand back and admire your brand new deck area which is made from everything that would typically end up cluttering your local landfill. ## Is composite decking better than wood? Composite decking is an excellent alternative to wood because it's virtually maintenance-free. [Wood decks](/guides/deck-builders/what-wood-to-use-for-decking) need yearly sealing and staining; composite decking boards don't. Composite decking is mostly made from recycled decking materials, so it makes sense environmentally as well. When you replace your wood deck with a composite one, you're doing three positive things for the environment: recycling old materials using plastic recycling bins, eliminating future waste (wood decks must be disposed of when they wear out) and creating less pollution by reducing or eliminating the need for harmful chemicals that are used in treating wooden decks. ## Is composite decking slippery? Manufacturers often add traction-enhancing features to their product lines-bevelled boards, textured surfaces-to avoid accidents on slippery surfaces. If you're concerned about safety, it's a good idea to wear shoes on your deck the same way you would in the house. Socks are slippery when wet and don't have anti-slip properties. Any composite board and other composite decking products, like all outdoor decks, should be inspected periodically for signs of wear and tear. Composite is slightly more resistant than wood to rot and deterioration due to moisture, but over time even the hardiest material will break down. Make sure your deck is properly cared for during winter months so that it doesn't warp or crack during cold weather. ## What types of bugs can affect composites? Since there are no natural resources that termites eat (they eat dead stuff), they don't feed on composite products. Ants will not get inside either, because composite doesn't have any cracks or voids for them to nest in. Composite is not susceptible to rot or mould, so there are no fungi that will attach themselves to the material either. Termites don't eat it, ants can't live in it and mould won't grow on it. The only downside is that termites will sometimes feed on fasteners that they find buried inside of the composite installation. ## How do you clean a deck made from composite materials? It's best to avoid using harsh chemicals on your deck. A mild detergent and water will remove normal dirt, stains and smudges. However - if the dirt is tough or caked-on - use a cleaner that's specifically designed for exterior wood surfaces. Always test a small area first before applying a new product to ensure it won't damage the colour of the boards. Keep in mind that some cleaners can damage certain types of plastic composites, so make sure not to mistake one for another. You shouldn't [need to oil it](/guides/deck-cleaning/what-is-the-best-decking-oil) regularly at all. ## Is composite decking any good? Composite decking is far better than wood because it doesn't need to be stained or sealed every year, so it saves you lots of time. Composite is also more resistant to rotting or warping than regular wood, or even [timber such as Merbau](/guides/deck-builders/what-is-merbau-decking), so the material will last much longer. Composite boards are very durable and won't dent, scratch or splinter as easily as some other materials do. The colour on composites usually won't fade over time either, so you won't have to worry about that aspect of maintenance. ## How does recycled plastic decking work? Recycled lumber addresses many concerns homeowners have with both polyethylene and lumber products - both aesthetically and environmentally. These products offer all the benefits of lumber, but with added enhancements. These enhancements include recycled content (up to 100%), rot resistance, insect resistance, warp resistance, PPS superior resistance, durability, structural integrity and strength depending on the manufacturing facility which could cause issues surrounding structural strength. ## What does composites' colour look like? Composites today come in a huge variety of colours - so you can choose one that matches the exterior of your home or complements your landscaping. The vibrant hues are made possible by using pigments rather than dyes; this technology allows for deeper shades that are more resistant to fading due to sunlight exposure. Plus, composite boards and other composite decking options have no knots or grain patterns, which means there are no imperfections that can absorb sunlight and change colour over time. Additionally, most manufacturers offer an array of shade options within the same product line using recycled hdpe as raw materials. ## What is the best composite decking material? Today's composite materials are much less expensive than they were even a few years ago. They also require very little maintenance, since they don't need to be stained or painted as traditional decks do. Composite boards are typically made from recycled plastic components, so they're an eco-friendly option too as are many plastic recycling bins. ## What are the best ideas for backyard decks? A custom-made rooftop deck offers a number of benefits that are perfect for your home. Not only will this space allow you to relax in privacy, but it can also save you money on landscaping costs and lower recycling costs by creating an outdoor extension of your indoor living space. This flexible design concept gives you endless options when it comes to designing or furnishing the area. Multi-level decks are another great option because they offer more than one level of usable space, which means there's room for various activities within different areas. ## What is synthetic wood made of? This material is made from plastic and wood fibre. As the name suggests, synthetic wood has properties very similar to natural wood, so it can be used in many of the same applications. However, because this material doesn't contain any actual wood, it's often less expensive than real dimensional lumber shape or lumber products. And thanks to its maintenance-free exterior and various colour options, you'll never have to worry about rot or warping either. However, the best option would be to use wood fibres with UV stabilised polypropylene plastic, wood-plastic composites and reclaimed hardwood fibre. ## What is the best composite decking? Today's composite materials offer a number of benefits that make them better than traditional wood decks. They don't require yearly staining as most woods do, they offer superior durability and warp resistance and their rich colours won't fade over time, although some may experience slight discolouration if they get wet frequently. Better yet, composite decks are environmentally friendly because they're made from recycled materials. If you are looking to build a deck yourself, [Work Safe Victoria](https://www.worksafe.vic.gov.au/preparing-build-timber-deck) has a handy guide to staying safe and beginning the project. ## Is wood or plastic better? As with most things, there are benefits and drawbacks to either material - so it ultimately comes down to the specific application in which you plan to use them. For example, some homeowners choose wooden decks because they love the look of traditional flooring material. However, depending on the type of soil where your house is located and how much everyday foot traffic your deck gets, real wood may not be a practical choice for you because it can rot or warp after extended exposure to moisture. Composite decks offer the same versatility as traditional lumber products without these issues, making them an attractive alternative even if they are more expensive such as high-density polyethylene produced deck boards, capped composite and unique co-extrusion process. ## Is composite wood strong? Composites are extremely strong and durable - so they can be used in a wide variety of applications. In fact, this material is often called "the green alternative" because it's made from recycled materials and doesn't require any staining or painting. It can be used in the packaging industry for food packaging, shampoo bottles using easily recyclable material and hardwood materials simply such as most commonly used plastic, post consumer material, mildew resistant, traditional pressure treated and prevalent plastic. This means that composite wood never needs to be replaced either. It will last for years without cracking or rotting thanks to its sturdy exterior.
