Heat Resistant Plaster is a replacement material for gypsum plaster where the temperatures are too high for gypsum plaster to stay on the wall. Heat Resistant Plaster is a fully blended fine powdered material which is mixed with water to a trowellable/floating consistency.

Heat Resistant Plaster should be used on walls and chimney breasts where the temperature is likely to exceed 50C – particularly around the so-called hole in the wall type fires and stoves. It is recommended that the plaster is used in combination with Heatproof Screed.
