waterproof tile backer board
Key words:
Beipeng® Waterproof Backing Board is made with Beipeng® extruded polystyrene board as the core, covered with alkali-resistant mesh and a specially formulated high-polymer mortar coating. The uniform and dense pores of the Beipeng® extruded polystyrene board create a closed-cell structure that does not absorb water and prevents water vapor penetration. The alkali-resistant mesh increases the strength and rigidity of the Beipeng® Waterproof Backing Board, and the surface polymer waterproof mortar is fully compatible with any modified polymer mortar, tile adhesive, or other decorative coatings. Beipeng® Waterproof Backing Board is commonly used in indoor applications where waterproofing and tiling are required for walls, floors, countertops, and other surfaces clad in ceramic tiles and stone.

Beipeng® XPS Waterproof Backing Panel
The Beipeng® waterproof backing panel is constructed with a core of Beipeng® extruded polystyrene board (XPS）, coated with alkali-resistant fiber mesh and a specially formulated polymer mortar. Its uniform closed-cell structure prevents water absorption and vapor transmission, while the mesh enhances structural strength and rigidity. The surface polymer waterproof mortar ensures full compatibility with modified polymer adhesives, tile sealants, and decorative coatings. This versatile solution is ideal for indoor applications requiring simultaneous waterproofing and tile installation on walls, floors, and countertops.
