Multifunctional Backer Board / Building Board / XPS Waterproof Board

Short Description:

Multifunctional backer board is made of extruded polystyrene rigid foam (XPS) as the core material, processed by compounding both sides with glass fiber mesh and cement-based composite coating. It is a high-performance building material suitable for wet areas or areas prone to moisture (bathrooms, kitchens, exterior walls, basements), providing long-term waterproofing while simplifying installation. It can prevent water infiltration, mold growth, structural degradation and enhance insulation performance. For thin bed tile laying or surface rendering finishing projects on walls and floors, this type of innovative building board is an extremely suitable substrate choice.

Product advantages

1. Prevents tile cracking: Unlike rigid tiles that crack from screed movement during drying, it lets sub-floors absorb such movement, keeping tiles intact.

2. Shortens construction time: Enables immediate tile laying post sub-floor walk ability (no long natural drying waits). Saves 3-4 weeks for cement/calcium sulfate screeds (tiles laid in 3-4 days) and ~3-4 months for concrete (tiles laid in ~2 months vs. 6 months traditionally).

3. Boosts efficiency & economy: Cuts time costs, aligning with "time is money" for architects, engineers and developers to enhance overall efficiency.
