STOPGAP 850 is a non-structural exterior resurfacing compound for use in light to medium duty applications to smooth and level rough or mechanically damaged concrete or sand/cement screeds. You can also leave STOPGAP 850 as a stand-alone exterior wearing surface.
Our exterior resurfacing compound is resistant to water once fully cured which makes it ideal in locations such as garages. It applies in thicknesses between 5-15mm.
To achieve a more natural surface finish and to reduce the potential for slipping, apply a scratch coat to the surface and brush finish it to a textured profile. STOPGAP 850 can also be pump applied up to 900m² per day, dependent upon manpower, thickness applied and equipment used.
