100% Waterproof. Ultra-lightweight. Ready to tile.
Revolutionize your wet-area renovations with this 1/2-inch Waterproof Tile Backer Board. Engineered for the modern master bath, this advanced substrate features a high-density Extruded Polystyrene (XPS) blue,closed-cell core that serves as a 100% waterproof vapour barrier and thermal insulator. The surface is armoured with a rigid polymer-modified cement coating, reinforced by a visible fibreglass mesh grid that grabs thin-set mortar with tenacious strength. Unlike heavy, crumbly cement board, this ultra-lightweight panel cuts effortlessly with a utility knife—no dust, no noise—creating a perfectly flat, thermally insulated canvas for your stone or porcelain tile.
Features
- 100% Waterproof Core: The blue Extruded Polystyrene (XPS) closed-cell foam is entirely impervious to water and steam, eliminating the need for additional waterproofing membranes behind the tile.
- Superior Bonding: The dark grid surface is a polymer-modified cement coating embedded with heavy-duty fibreglass mesh, creating a rigid, textured surface that instantly anchors thin-set mortar.
- Ultra-Lightweight: Weighs a fraction of traditional cement board, making it easy for a single person to carry 4x8 sheets up stairs and into tight bathroom spaces.
- Dust-Free Installation: Cuts easily with a standard utility knife (score and snap) without generating the silica dust or mess associated with cutting cement board.
- Thermal Insulation: Provides a thermal break (R-Value ~2.5-3.0), keeping shower walls warm to the touch and reducing condensation compared to cold backer boards.
- Large Format: The 4' x 8' size reduces the number of seams required on large shower walls, speeding up installation.
