MAPEI, one of the world’s leading manufacturers of chemical products for the building industry and has contributed to the construction of some of the most important architectural and infrastructure works worldwide, announces the arrival of Mapeguard Board, a multipurpose, premium-performance, lightweight, high-density, waterproof backer-board panel that is designed for use under ceramic tile and stone installations. The board features an extruded polystyrene core and a high-strength, waterproof membrane and facer on both sides to provide water and vapor protection. 

“For use under ceramic tile and stone installations, the rigid board is high-strength and perfect for residential and commercial applications,” said Brian Pistulka, MAPEI’s Business Manager for Tile & Stone Installation Systems.

Featuring a multi-layered design, Mapeguard Board is available in a variety of thicknesses ranging from 1/4" (6 mm to 2" (5 cm). Lightweight and easy to handle, it can be quickly and easily installed.

“Although the high-density material is strong and ridged, it actually cuts easily with a standard utility knife,” said Pistulka. “And it fits in with our other waterproofing products, such as Mapeguard WP ST sealing tape, Mapelastic Aquadefense or Mapelastic Turbo, to create a system solution for showers.”

Mapeguard Board features a low perm rating and is approved for use in steam rooms and showers. It can also be used in interior residential and commercial floors, walls and ceilings. In addition to tile installations, the ridged board can be used for the fabrication of shower benches, shelves, seats, niches and curbs.

“If you are installing backsplashes and countertops, or showers and tub surrounds, now you can use MAPEI’s Mapeguard Board to deliver a dimensionally stable substrate, which then can be covered by MAPEI’s waterproofing, mortars and grouts. With Mapeguard Board, we now offer the complete system solution from the substrate itself to the sealer,” said Pistulka.
