For professional tile installers and remodelers who live in showers, tub surrounds, and wet rooms, the Wedi Building Panel 36" x 60" x 1/2" Waterproof Tile Backer Board solves a lot of the pain points of traditional cement board. Each 3' x 5' x 1/2" panel combines a waterproof XPS foam core with a cementitious, mesh-reinforced surface, giving you a backer board that’s both light to carry and tough enough for demanding tile installations. Because the foam core is 100% waterproof and mold proof, you’re not relying on a separate membrane to protect the framing—once seams and fastener heads are sealed with Wedi joint sealant, you’ve created a continuous waterproof envelope behind the tile.

On the job, the advantages are obvious: panels are easy to lift and position, even in tight bathrooms or on upper floors. You can score and snap them with a utility knife or cut them with standard tools without generating the heavy silica dust associated with cement board. That keeps the work area cleaner and safer, and it speeds up layout work when you’re fitting around niches, benches, and plumbing penetrations. The even, stable surface is ideal for large-format porcelain, thin-body tile, stone, and glass mosaics, helping you achieve consistent grout joints, flat walls, and smooth transitions at corners and changes of plane.

This pallet includes 50 panels, giving you coverage for up to 750 sq. ft. of walls and floors—perfect for multi-bath projects, small multifamily jobs, or stocking up for recurring shower installations.

The panels are designed for interior wet area applications on walls, floors, ceilings, and countertops, and they can be installed over wood or steel studs or over stable existing substrates according to Wedi’s installation guidelines. The foam core is HBCD-free and made using foaming agents that meet modern environmental standards, while the system as a whole has been tested to key industry performance standards (including ANSI A118.10 and ASTM C578) recognized in the tile industry.

For installers who care about speed, cleanliness, and long-term performance, this Wedi 3' x 5' x 1/2" waterproof tile backer board pallet offers a dependable, professional-grade substrate that keeps callbacks down and productivity up.
