About This Product
Waterproof Tile Backer Board for Wet Areas
wedi® Building Panels are waterproof tile backer boards with a closed-cell extruded polystyrene foam core. The core is waterproof, mold-proof, and insulating, making the panels suitable for tiled shower and tub surrounds and other wet-area applications.
Cement-Coated Surface for Tile Installation
Both sides of the panel feature fiberglass mesh embedded in a cement resin coating. The reinforced surface provides tile backing strength while its waffle-pattern texture gives thin-set mortar a surface to mechanically bond to.
Floors, Walls, Countertops, and Custom Tile Structures
Building Panels can be used for tiled shower and tub walls, floors over wood or concrete subfloors, countertops, kitchen backsplashes, and custom tiled seats and benches. On floors, the foam core also creates a thermal break and provides insulation value.
Integrated Backer Board and Waterproofing
In wet-area installations, wedi Building Panels combine tile backing and waterproofing in one panel rather than requiring cement board followed by a separate liquid waterproofing system. This reduces installation steps, curing time, and labor.
Common Questions
Frequently Asked Questions
Are wedi Building Panels waterproof?
Yes. wedi Building Panels have a closed-cell extruded polystyrene foam core that is internally waterproof.
Can wedi Building Panels be used in showers and tub surrounds?
Yes. They are designed for tiled shower and tub wall surrounds and can be used as part of a wedi shower system.
Can wedi Building Panels be installed on floors?
Yes. They can be used under tile over wood and concrete subfloors. The foam core creates a thermal break and provides insulation value.
What other applications can wedi Building Panels be used for?
They can be used for tiled countertops, kitchen backsplashes, and construction of tiled seats and benches in wet areas.
How does thin-set mortar bond to wedi Building Panels?
Both sides are reinforced with fiberglass mesh embedded in a cement resin coating. The surface has a waffle-pattern structure that provides a bonding surface for thin-set mortar.
Do wedi Building Panels require separate waterproofing over the entire panel?
The panel itself is waterproof. Wet-area assemblies must still be installed and sealed at seams, fastener penetrations, transitions, and other required connection points according to the applicable wedi installation instructions.
