STOPGAP 700 SUPERFLEX is a fast drying, fibre reinforced self-levelling smoothing underlayment designed for use on plywood, sand/cement concrete and steel sub floors prior to the installation of new floorcoverings.

STOPGAP 700 SUPERFLEX allows resilient floorcoverings to be installed in as little as3 hours at 20°C, making it ideal for fast-track installations and minimising downtime.

STOPGAP 700 SUPERFLEX 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.

STOPGAP 700 SUPERFLEX can be used to encapsulate wire heating systems over plywood up to a maximum thickness of 10mm.

It is essential to prime absorbent subfloors with dilute STOPGAP P131 primer toprevent uncontrolled rapid drying of the underlayment.

Steel surfaces must be primed with an appropriate epoxide resin deck plate primer orSTOPGAP F77 before priming with neat STOPGAP P131.

The primer should be used in accordance with instructions printed on the bottle andmust be allowed to dry before applying the smoothing underlayment.
