Crack prevention uncoupling mat
Custom Building Products has introduced the RedGard uncoupling mat.
Designed for installations using polymer-modified thin set mortars, the mat is a crack isolation, waterproofing and vapor management membrane for tile, porcelain and natural stone installations over most substrates, including oriented strand board (OSB), plywood and concrete.
Featuring heat-welded fleece on top and bottom, the product provides crack-isolation performance by locking mortar onto the mat at every point of contact for a strong mechanical bond, the company says.
No mechanical fasteners are required. The uncoupling mat is engineered to absorb stress and preserve the surface and integrity of tile and grout.
