Description
STOPGAP 850 is a non structural exterior grade smoothing compound for use in light to medium duty applications to smooth and level rough or mechanically damaged concrete or sand / cement screeds.
STOPGAP 850 can be left as a stand-alone exterior wearing surface. To give a more natural surface finish and to reduce the potential for slip, if left uncovered, it is recommended that a scratch coat is applied to the surface and brush finished to a textured profile.
STOPGAP 850 can also be pump applied up to 900 m² per day, dependent upon manpower, thickness applied and equipment used.
Priming:
Absorbent surfaces – Concrete and sand/ cement screeds must be primed with STOPGAP P131 diluted 1:7 with water
