F Ball StopGap 1100 Smoothing Underlayment 22kg
STOPGAP 1100 GYPSUM is a self-levelling smoothing underlayment designed specifically for application over sound calcium sulphate (e.g. anhydrite) screeds prior to the installation of new floorcoverings.
It's dimensionally stable and is supplied as a pre-blended dry powder, which is designed for application between 2-10mm. It is protein-free which allows it to be used in biologically sensitive areas such as hospitals.
This product can be used over a wide range of other subfloor types including STOPGAP waterproof surface membranes, sand/cement screeds, concrete, sound asphalt, granolithic, terrazzo, epoxy and polyurethane resins, ceramic and quarry tiles.
A 22kg bag of STOPGAP 1100 GYPSUM mixed with 5.5 litres of clean water will cover approximately 5.0m² at a thickness of 2-3mm.
