ALFA COAT 5 BITUMEN PAINT
Description
Alfa Coat 5 Bitumen Emulsion is a single-pack, fibrated and stable water-borne emulsion which cures to form a firm and flexible bitumen waterproofing membrane. Alfa Coat 5 is designed for use on horizontal and vertical surface. Alfa Coat 5 is suitable for use as waterproof membrane on concrete, asbestos cement, roofing felt, mastic asphalt, slates, tiles and metal surface.
Application
Provides a vapour barrier forcold storage rooms, mushroom houses and food stores.This applied to protect concrete from carbonation and sulphate attack and acts as a protective coating against corrosionof pipes, structural steel works and other metallic equipment.
