Product description
Product Overview
Waterproof XPS Tile Backer Board uses a closed-cell extruded polystyrene core reinforced on both surfaces with alkali-resistant mesh and a polymer-modified mortar coating. The foam core resists water absorption and helps limit water-vapor transmission, while the reinforced coating provides rigidity and a compatible bonding surface for tile adhesive, polymer mortar and decorative coatings.
Key Benefits
- Waterproof and moisture resistant for wet areas.
- Lightweight and easy to carry, cut and install.
- Reinforced surfaces support tile and stone bonding.
- Thermal insulation helps reduce heat loss.
- Suitable for walls, floors, countertops and leveling applications.
- Custom length, width and thickness available.
