A method of protecting an object from fire damage by coating the object with a slurry made from hydrated metal silicate particles and an aqueous alkali metal silicate solution. The slurry is applied before there is significant absorption of water into the particles from the solution. Upon heating, the coating expands to form a foam which, because of the equilibrium of water formed between the particles of sodium silicate, is rigid at high temperatures. |
