ACTFLEX 900R

Single-Fleece Internal Undertile Sheet Membrane

Heat-weldable, single-fleece Butynol sheet membrane designed for fully bonded internal wet-area waterproofing beneath tiles or screed.

ACTFLEX 900R is an internal-only waterproofing sheet membrane for showers, bathrooms, and ensuites. It has a light grey Butynol core, white nonwoven fabric on the top face for bonding tiles or screed, and a smooth underside for full adhesion to the substrate.
