Envirograf EP/CP Intumescent for Plasterboard - 5 Litres

EP/CP is an intumescent water based coating. Allow to dry thoroughly. Dries in about 30 minutes.


A white or coloured aqueous dispersion coating, offering fire protection to plasterboard and lath-and-plaster ceilings of various thicknesses. It develops a microporous intumescent layer with a smooth decorative finish. When attacked by fire, the intumescent material protects the coated areas integrity and insulation for a period in excess of one hour.
