Calcium sulfate-based, self-levelling smoothing underlayment.
STOPGAP 1100 GYPSUM is a self-levelling smoothing underlayment designed specifically for application over sound calcium sulfate (e.g. anhydrite) screeds prior to the installation of new floorcoverings.
Dimensionally stable and is supplied as a pre-blended dry powder, which is designed for application between 2–10 mm. It is protein-free which allows it to be used in biologically sensitive areas such as hospitals.
Calcium sulfate-based and is particularly compatible for smoothing and levelling similarly constructed screeds but may also 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.
Can be pump applied up to 1500 m² per day, dependent upon manpower, thickness applied and equipment used.
IT IS ESSENTIAL TO PRIME ALL SURFACES.
