Stopgap 1100 Gypsum  


Designed specifically for use over calcium sulphate based screeds, such as anhydrite, new Stopgap 1100 Gypsum provides a smooth and level surface prior to the installation of new floorcoverings.

STOPGAP 1100 GYPSUM is 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.

STOPGAP 1100 GYPSUM is calcium sulphate based and is particularly compatible for smoothing and levelling similarly contructed 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.

STOPGAP 1100 GYPSUM can be pump applied up to 1500m2 per day, dependent upon manpower, thickness applied and equipment used.

  • Coverage 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.
