Application

Suitable:

  • For preparing sound internal subfloors prior to the installation of new floorcoverings.
  • For use in clinical and biologically sensitive areas such as hospitals, laboratories, clean rooms etc.
  • For use over a wide range of other subfloor types including STOPGAP waterproof surface membranes, sand/ cement screed, concrete, granolithic, terrazzo, asphalt, steel, old vinyl asbestos tiles, epoxy and polyurethane resins, ceramic and quarry tiles.

Description

STOPGAP 1200 is a low odour, fast setting, fast drying, two component smoothing underlayment.

STOPGAP 1200 is particularly suitable for use over old adhesive residues (including bitumen and carpet tile tackifiers) without the need for priming. STOPGAP 1200 can be used for patch filling timber floors prior to overlaying with plywood.

STOPGAP 1200 is unaffected by moisture and is suitable for application over damp, clean, uneven concrete and sand/cement screeds, prior to application of STOPGAP waterproof surface membranes or STOPGAP ISOLATOR MEMBRANE.


Priming:

  • Absorbent surfaces - Very absorbent surfaces can be primed with STOPGAP P131 diluted 1:4 with water to assist in preventing rapid drying, pin holing and to aid the flow and workability. If using under a DPM onto damp concrete or sand/cement screeds, prime with STOPGAP P131 diluted 1:7 with water, prior to application.
  • Non-absorbent surfaces – Where underfloor heating is present or when laying direct to STOPGAP waterproof surface membranes laid longer than 24 hours prime with neat STOPGAP P141.
  • Primers should be used in accordance with instructions printed on the bottle and must be allowed to dry before applying the smoothing underlayment.
