A free-flowing asbestos-free solid composition, which on admixture with water forms a slurry sprayable onto a substrate to form a non-combustible coating protective against fire, contains a water-soluble thickener e.g. a cellulose ether and mica in addition to the conventional ingredients exfoliated vermiculite, water-settable particulate cementitious binder such as Portland cement, and air-entrainment agent. Inclusion of the thickener and the mica enables a coating giving a desired degree of fire protection to be built up more quickly. |
