The mortar side of the SubVap tanking system
SubVap 20Kg is the cement powder that combines with the SubVap 10L acrylic resin to create the tanking layer beneath a microcement wet room. Waterproof yet vapour-permeable and flexible enough to bridge cracks over 1 mm, it is engineered for the movement and moisture load of walk-in showers and Irish wet-room installations.
Applied in two coats to a total of 3–4 mm at 1.7 kg/m² per millimetre, with an optional alkali-resistant mesh between coats. Also specified on terraces, balconies, basements, pools and drinking-water tanks.
