1. Is second-gen WPC decking truly waterproof and rot proof for outdoor use?
Yes. Adopting upgraded double-layer co-extruded technology, this decking features an ultra-low water absorption rate. It effectively blocks water penetration, resists mold, mildew and structural rot caused by humid weather, and will not decay or deform even in long-term outdoor rainy and damp environments.
2. How long can the upgraded second-gen WPC decking last outdoors?
With standard installation and daily use, the upgraded second-generation WPC decking has an outdoor service life of 25 to 30 years. The optimized composite formula and protective outer layer greatly enhance aging resistance, delivering far longer-lasting performance than traditional solid wood flooring.
3. What joist spacing is required for installation?
For residential outdoor patio and backyard installation, the standard joist spacing is 300mm. Strict compliance with this spacing ensures uniform force on the decking boards, avoiding sagging and cracking to maintain long-term structural stability.
4. Is it necessary to reserve expansion gaps during installation?
Yes. A 5-8mm expansion gap must be reserved during installation. The decking will slightly expand and contract with outdoor temperature changes. Reasonable gaps effectively prevent board arching, deformation and cracking caused by thermal expansion and cold contraction.
5. Does this WPC decking need regular maintenance?
No complicated maintenance is required. Thanks to its excellent waterproof and anti-rot properties, it needs no painting, waxing or anti-corrosion treatment. Daily cleaning only requires simple water rinsing, saving plenty of time and maintenance costs.
6. Can the decking be installed on wet or waterlogged ground?
No. Installation on completely closed and waterlogged ground is not allowed. Long-term water accumulation will affect the base stability and reduce the service life of the decking. The installation base must be kept flat, dry and well-drained.
