Application

Suitable:

  • For use in light to heavy-duty areas for preparing sound absorbent and non-absorbent subfloors prior to the installation of new floorcoverings.
  • For use over a wide range of subfloor types including sand/ cement screed, concrete, calcium sulphate (e.g. anhydrite), minimal adhesive residues, sound asphalt, granolithic, terrazzo, epoxy and polyurethane resins, ceramic and quarry tiles and STOPGAP waterproof surface membranes.

Description

STOPGAP 300 is a fast drying, self-levelling smoothing compound.

STOPGAP 300 is dimensionally stable and is supplied as a pre-blended dry powder designed for application between 2–20 mm. It is protein-free which allows it to be used in biologically sensitive areas such as hospitals.


Priming:

  • IT IS ESSENTIAL TO PRIME ALL SURFACES.
  • Absorbent surfaces - Prime with dilute STOPGAP P131 to prevent rapid drying of the compound.
  • 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 sound asphalt, minimal adhesive residues, terrazzo, quarry tiles and STOPGAP waterproof surface membranes should be primed with neat STOPGAP P131 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 compound.
