3 Product Description
A waterproof, vapor-proof uncoupling membrane that can be used for
crack-isolation in most tile, porcelain or natural stone installations, and
can be applied over challenging substrates such as installation over
green (young) concrete and single ply 19.2" (49 cm) o.c. wood framed
floors.RedGard®UncouplingMatisdesigneddifferentlythanbonded
membranes. When exposed to excessive substrate movement it
absorbs stress and preserves the surface and integrity of the
tile.RedGard®UncouplingMat'sbondinglayershavereinforcedfleece
which locks mortar into the mat, ensuring strong, reliable installations.
