Heat Resistant Plaster 12.5KG Tub


Out of stock

Heatproof resistant plaster is a replacement material for gypsum plaster where the temperatures are too high and gypsum plaster would not remain on the wall or would craze and crack. Heat resistant plaster is a fully blended fine powdered material which is mixed with water to a trowellable consistency. It is recommended that heat resistant plaster is used in conjunction with heatproof screed.

  • High temperature smooth finish
  • Protection to 500 degrees C
  • Can be used over heat proof screed
  • Designed for plastering areas adjacent to heat sources
  • Heat resistant plaster has a shelf life of 12 months
  • The 12.5 kg tub will cover approximately 1.25 sq metres at the recommended thickness of 5mm.

How to prepare and use heat resistant plaster

Ensure all surfaces where heat resistant plaster is to be applied are clean and free from grease, dust and dirt. Remove all old traces of old screed and plaster on the wall to be treated. Prepare the area by coating with PVA and re-render with heat proof screed prior to skimming with heat resistant plaster. Mix the plaster with clean water using a mixer drill attachment (it is not possible to mix by hand). Allow about ten minutes to get the material onto the wall and about an hour trowelling. Leave for three days to dry naturally before any heat is applied. Clean any tools immediately with water.
