STOPGAP 850 is a non-structural exterior grade resurfacing 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 900m² per day, dependent upon manpower, thickness applied and equipment used.
