Whether you want to install decking for a garden floor or wall cladding, choose WPC deck. It is durable, water-resistant, strong, and offers a unique look. Also, this decking is cost-effective, requires less maintenance, and lasts for years. As there are different types of WPC decks available, you can find your perfect match easily.
In this comprehensive guide, I have mentioned the definition of WPC decking, its surface treatment, benefits, uses, and more. Read this whole article to become an expert on WPC deck–
Wood plastic composite (WPC) decking is made from wood fiber combined with different types of thermoplastics. As this material has 50-75% wood content, you can get a natural look. Also, the more wood, the stronger the decking will be. Therefore, you can use it for outdoor decoration like balconies, terraces, walkways, and more.
Unlike traditional wood decking, WPC is resistant to moisture, insects, and decay. This way, it offers homeowners like you a long-lasting decking solution that requires minimal maintenance. It is also highly customizable and comes with various finishes and textures.
Below, I have mentioned some additional information about the WPC deck–
The main components of the WPC deck are recycled hardwood fibers and plastic. Basically, this contains 60% wood and 30% plastic. And the other 10% is additional chemicals. However, this equation can vary based on different manufacturers.
The dimensions of the WPC depend on specific needs. However, the common dimensions are 140x20mm, 140x25mm, 140x23mm, 150x23mm. As the custom option is available, you can make an order based on your project’s requirements.
WPC decks can be of different types and can match different applications. For instance–
Traditional or first-generation WPC decks are made from a blend of wood fibers and plastic without a protective outer layer. This is cost-effective, and decks are more susceptible to damage from UV rays, moisture, and mold. Its lack of protective coating leads to higher maintenance requirements and a shorter lifespan compared to newer co-extruded options.
Embossed decks feature a textured surface that mimics the appearance of natural wood grain. This design not only enhances aesthetic appeal but also provides additional slip resistance. The embossing process adds depth and character to the decking while maintaining the low-maintenance benefits typical of composite materials.
3.2nd Generation Co-extruded Deck
A 2nd Generation co-extruded deck refers to a type of composite decking material that is made using advanced co-extrusion technology. In this process, two or more layers of materials are combined during manufacturing. One layer typically has a durable, weather-resistant plastic exterior, and the other layer has a wood composite core. The second generation of this technology enhances durability, resistance to staining, fading, and more.
ASA co-extruded decks are a third-generation advancement in WPC technology. This used Acrylonitrile Styrene Acrylate (ASA) for the outer layer. This material offers exceptional weather resistance and color retention, perfect for outdoor environments. The three generations of co-extrusion signify continuous improvements in durability, aesthetics, and overall performance.
Embossed: Embossing means pressing patterns or textures onto the WPC surface during manufacturing. Through this process, the WPC deck has a wood-like look and increases slip resistance. And you can use it in high-traffic areas.
Engraving: Engraving is a precise treatment where patterns or designs are carved into the WPC surface. This method is often used for decorative purposes and is perfect for custom designs or branding. However, this technique can require more maintenance to keep the intricate details clean.
Co-extrusion: This is a modern surface treatment where an additional protective layer is bonded to the WPC core during manufacturing. This layer enhances resistance to UV rays, stains, and moisture. Plus, co-extruded WPC decking is highly durable and requires minimal maintenance.
Normal: Normal or untreated WPC decking surfaces retain their original finish without additional textures or coatings. While cost-effective, these surfaces can be more prone to fading, scratches, and staining compared to treated options. However, by regular cleaning and occasional sealing, you can help maintain their appearance.
WPC decking is a durable, eco-friendly material combining wood fibers and synthetic polymers. Its quality is defined by compliance with standards like ASTM E84 for flame spread and EN -1 for fire resistance, ensuring safety in construction.
Besides, WPC decking offers inherent fire-resistant properties, low flame spread, and self-extinguishing capabilities. Therefore, you can say it is safer than traditional wood. And its structural stability must meet NCC performance requirements, including slip resistance and termite protection. Not to mention that the proper installation and adherence to standards are crucial for performance and safety.
You can use the WPC deck in a wide range of applications from the garden floor to the swimming pool floor–
Invented in Milan in by an Italian plastics company, WPC was initially called Plastic-Wood. By the mid-60s, Icma San Giorgio patented the process of mixing wood fibers with thermoplastics. Though still new in some industries, WPC gained popularity in the late 80s for door frames, benches, and furniture.
By the 90s, it became a top choice for decking, fencing, and cladding. WPC’s longevity, water resistance, and eco-friendliness make it a strong alternative to timber.
The advantages of WPC decking are several. It is strong, fire resistant, and more–

The other best part about this deck is its aesthetically pleasing appearance and its natural wood look. By using it, you can increase outdoor spaces with its versatile design and colors.
WPC decking features a non-slip woodgrain surface. This ensures safety by reducing the risk of slips and falls. This makes it suitable for family homes and public spaces.
Let’s take a look at the comparison between WPC decking and other materials–
As the WPC decking is made with plastic and wood fibers, it can resist insect attack, decay, fading, warping, and more. Therefore, it can withstand harsh weather and extreme climate conditions. On the other hand, traditional wood decking has natural wood strengths. However, it has problems like warping, insect infestations, etc.
Besides, WPC decking is designed for versatile use, it comes with different hues, styles, finishes, and more. While conventional decking does come with natural wood beauty, it offers limited options for painting and staining.
WPC decking is easy to install and lightweight, offering a better aesthetic look with wood-like textures. Also, it can resist moisture and mold and is perfect for outdoor use. Whereas, concrete floors are highly durable, weather resistant, and low cost. And you can use it for heavy loads and require less maintenance. However, it lacks aesthetic appeal and can be cracked over time.
Before installing, you have to take some essential steps to make the installation process easy. So follow the below guides–
The shape and size of your WPC deck depend on the available outdoor space and its intended use. A simple rectangular design is easier for DIY projects, while irregular or multi-level designs add visual interest but require more planning.
On the other hand, a strong substructure is key to a durable WPC deck. So you can use pressure-treated wood or metal for joists and beams. Besides, proper drainage prevents water pooling, which can damage the deck over time. And adequate ventilation beneath the deck prevents moisture buildup, which can lead to structural deterioration.
Before starting the installation of WPC decking, check local building codes and regulations. And if needed, obtain necessary permits, and ensure your design complies with safety standards, such as railing height and load-bearing capacity. In some cases, professional engineering approval can be required for structural plans.
Gather essential tools like a circular saw, drill, level, tape measure, and miter saw. Also, ensure you have WPC boards, corrosion-resistant screws, joists, and footings. You can create a detailed materials list based on your design to avoid delays during construction.
The initial cost of installing a WPC deck includes materials and labor. On average, WPC decking price ranges from $25.36–$63.40 per m² depending on quality. For a standard 15 m² deck, you expect to pay around $1,950, with installation. However, larger decks of 30 m² can cost approximately $3,350.
WPC decks are low-maintenance compared to traditional wood. And maintenance costs like cleaning products are $3.80–$7.60 per tube of sealant and occasional oil finishes are $57.06–$76.08 per gallon. Over time, annual maintenance costs average $63.40–$126.80.
Installing WPC flooring requires you to follow some basic steps. For instance–
Let’s see a detailed breakdown of the steps required to install WPC decking–
You will get efficient and thoughtful service from U-timber.
Step 1: Surface preparation (cleaning and leveling)
Before installation of the WPC deck, dry and clean the area first. For this, you have to remove any weeds, debris, or uneven areas. For soil installations, you can create a sturdy base using compacted gravel or concrete.
Step 2: Frame construction and fixing
Now, construct a joist frame to support the decking boards. And joists should be spaced evenly, for instance, you can use 300mm for square hollow decking, 350mm for circle hollow decking, and 400mm for solid decking. Also, you have to secure joists to the ground using expansion screws or self-tapping screws. Then, ensure all joists are level and properly aligned for better performance.
Step 3: Installation of starter clips
In this step, attach starter clips along the perimeter of the joists. These clips secure the first board in place. And you should maintain a gap of approximately 8mm between the starter clip and any walls or boundaries.
Step 4: Location and spacing of WPC flooring
Begin by laying the first WPC decking board into the starter clips. And use spacers to maintain an even gap (typically 6mm) between boards for natural expansion and contraction of temperature changes. After that, align boards carefully using a spirit level to ensure they remain flat and straight throughout the installation.
Step 5: Fastening methods (concealed and face screwing)
You can use hidden fasteners like clips for a seamless look or face screws for visible fixing. For this technique use clips between boards and secure them to the joists with screws for concealed fastening. Another fastening method is face screwing. For this, you have to pre-drill holes in the boards to avoid splitting. Next, you can secure them directly to the joists with stainless steel screws.
Step 6: Reservation of expansion gap
Leave an expansion gap of approximately 6 to 10mm around the perimeter of the deck. This will accommodate material expansion due to weather changes.
Let’s see here some advanced WPC deck installation techniques to get smooth performance–
WPC decking expands and contracts with temperature changes. So, you have to leave expansion gaps between boards and secure them with hidden fasteners for flexibility. Also, end caps or expansion joints can be helpful in preventing warping. However, if you install it during moderate temperatures, it can minimize post-installation movement.
For a polished look, you can conceal edges with fascia boards, trim, or picture-framing techniques. Also, use color-matched edge covers or mitered corners for a seamless finish. Not to mention that the skirting can hide exposed board ends. Hence, with proper finishing, you can enhance aesthetics and protect edges from moisture, dirt, and wear over time.
Installing a DIY WPC deck is simple if you follow some steps.
