Waterproof Exterior Cladding

WPC Waterproof Cladding(Waterproof Exterior Cladding): Focusing on Waterproof Protection, a Professional Decorative Material for Long-lasting Building Durability 

In architectural decoration, humid environments (such as bathrooms, kitchens, basements, and outdoor pool surroundings) have always been a difficulty in material selection—traditional decorative materials are prone to mildew, rot, and deformation due to water seepage, which not only affects the appearance but also shortens the service life of buildings. As a professional wood-plastic composite material developed for waterproofing needs, WPC Waterproof Cladding(Waterproof Exterior Cladding) takes "high waterproofness" as its core design goal. Through a special waterproof formula and multi-layer structural technology, it deeply combines the natural texture of wood fibers with the strong waterproof performance of polymer materials. It can maintain stable performance in environments with long-term water contact or humidity, without seepage or damage. It is widely used in bathroom walls, kitchen countertop facades, basement walls, outdoor water-facing platforms, pool surrounding decorations and other scenarios, providing an integrated "waterproof + decoration" solution for moisture-prone areas of buildings and filling the gap of traditional decorative materials in humid environment applications.

Major Advantages of the Product

✅ ​​​​​​​Multi-layer Waterproof Structure, Almost Zero Water Seepage Rate:

Waterproof Exterior Cladding adopts a three-layer waterproof structure of "surface waterproof film + core layer waterproof substrate + bottom moisture-proof coating"—the surface layer is treated with a nano-level waterproof coating to form a dense water-repellent barrier, and water droplets can roll off directly when falling on the surface without penetration or hanging; the core layer is made of high-density waterproof polymer materials combined with wood fibers, with a moisture content controlled below 2%, blocking water penetration from the substrate level; the bottom moisture-proof coating further isolates the reverse penetration of base moisture. Tests show that the product's 24-hour water absorption rate is only 0.05%, far lower than the national standard, and the water seepage rate is almost zero, which can be used in long-term immersion in water.

✅ Mildew and Corrosion Resistance, Adapting to Harsh Humid Environments:

Humid environments are prone to mildew and bacteria growth, and may have chemical erosion such as detergents and disinfectants. It is added with special mildew inhibitors and anti-corrosion components, which can effectively inhibit the growth of mildew and bacteria, and has good tolerance to common acid and alkali substances (such as white vinegar, soapy water, disinfectant). Long-term contact will not cause surface corrosion, discoloration, or structural damage, especially suitable for bathrooms, kitchens, laboratories and other special humid scenarios with chemical erosion risks.

✅ Temperature Difference and Aging Resistance, Suitable for All-climate Scenarios:

Different from the problem that ordinary waterproof materials are prone to cracking and aging under extreme temperature differences, it can withstand extreme temperature changes from -40℃ to 80℃ through formula optimization, and there is no cracking, deformation, or delamination after 50 cycles of thermal cycle testing; at the same time, the surface layer is added with anti-ultraviolet additives, which can resist ultraviolet aging when used outdoors, avoiding the decline of waterproof performance and appearance fading due to long-term sun exposure. It is suitable for cold and humid areas in the north and can also meet the use needs of high-temperature and high-humidity environments in the south.

✅ Easy to Clean and Maintenance-free, Reducing Usage Costs:

In humid environments, the surface of traditional materials is prone to scale and stains, which are difficult to clean, and regular waterproof repairs are required. The surface of it is smooth and water-repellent, and scale and stains can be removed by wiping with clean water or ordinary detergents without residue or traces; moreover, the product's waterproof performance is stable, with a service life of 15-20 years, and no additional waterproof agents or waterproof repairs are needed during the period, which greatly reduces the workload of cleaning and maintenance and lowers long-term usage costs.

✅ Environmental Protection, Safety and Odor-free, Suitable for Sensitive Scenarios:

It is made of environmentally friendly waterproof resin and recycled wood fibers, without formaldehyde, heavy metals, or volatile organic compounds. The formaldehyde emission is ≤0.01mg/m³, far better than the national standard; there is no toxic wastewater or waste gas emission during the production process, which meets the national environmental protection production requirements. The product has no pungent odor after installation, and can be directly used in sensitive scenarios such as children's room bathrooms and elderly room bathrooms with high environmental safety requirements, providing a healthy and safe environment for users.

✅ Lightweight and Easy to Cut, Suitable for Complex Shapes:

Despite its strong waterproof performance, the weight of it is still controlled at 6-8kg/㎡, much lighter than traditional waterproof stone (25-30kg/㎡) and ceramic tiles (20-25kg/㎡), which will not increase the load-bearing burden of walls or bases, especially suitable for the renovation of humid areas in old buildings. At the same time, the product has moderate hardness and can be cut, chamfered, and holed with ordinary electric saws and wallpaper knives, easily adapting to complex shapes such as bathroom corners and pipeline surroundings. No professional waterproof construction team is needed, and ordinary decoration personnel can operate it, reducing the construction threshold.

✅ Application of 8 Colors

Waterproof Exterior Cladding provides 8 practical colors suitable for humid scenarios, balancing waterproof function and visual coordination: light beige and pure white are suitable for spaces that require a bright and clean atmosphere such as bathrooms and kitchens, and can enhance the transparency of the space when matched with lighting; light gray and dark gray are suitable for modern minimalist style basements and outdoor water-facing platforms, and look more calm when matched with stone and metal elements; light blue and cyan green fit the "water theme" design of pool surroundings and bathroom spaces, creating a fresh and natural visual effect; light oak color and dark walnut color can create a warm and natural atmosphere in kitchens and basements, suitable for new Chinese and pastoral style designs, meeting the style needs of different humid scenarios.
