Description

STOPGAP 200 is a rapid drying, two component, low odour acrylic, self-levelling smoothing underlayment suitable for use in light to heavy-duty applications for preparing sound absorbent and non-absorbent subfloors prior to the installation of new floorcoverings.

STOPGAP 200 is dimensionally stable and is supplied as a pre-blended dry powder and acrylic liquid, which is designed for application between 2 - 20mm.

STOPGAP 200 is suitable for use over a wide range of subfloor types including STOPGAP waterproof surface membranes, sand/cement screed, concrete, syntheticanhydrite, sound flooring grade asphalt, granolithic, terrazzo, epoxy and polyurethaneresins, ceramic and quarry tiles.

STOPGAP 200 powder when mixed with STOPGAP 200 Acrylic liquid is suitable for usein clinical and biologically sensitive area such as hospitals, laboratories, clean rooms etc

IT IS ESSENTIAL TO PRIME ALL SURFACES

Absorbent surfaces - Prime with dilute STOPGAP P131 to prevent rapid drying of the underlayment.

For dry (<75% RH) and suitably prepared calcium sulphate screeds, prime with two coats of STOPGAP P121. The first coat should be diluted 1 part primer to 1 part water. Once dry, prime with a second coat of neat STOPGAP P121.

Non-absorbent surfaces – such as STOPGAP waterproof surface membranes, sound flooring grade asphalt, minimal adhesive residues, terrazzo, and quarry tiles, should be primed with neat STOPGAP P141 to ensure that good adhesion is obtained between the underlayment and substrate.

Primers should be used in accordance with instructions printed on the bottle and must be allowed to dry before applying the smoothing underlayment.
