Spread Rate

On smooth sealed surfaces a spread rate of 8 -10 sq metres per litre is obtained per coat. On previously unpainted plaster the spread rate is dependant on the porosity and profile of the plaster.


Ensure that the surface to be coated is free of dirt and loose material. Prime friable surfaces with WeatherPrufe Masonry Primer prior to coating, at a spread rate of 8 – 10 sqm per litre, allowing 6 – 8 hours drying time. Apply with lambs-wool roller or good quality brush. Apply two coats allowing 4 – 6 hours drying time between coats.
