A fire resistant composition comprises an alkali metal silicate, especially sodium silicate, and a starch, in a liquid vehicle and optionally containing a film-forming binder, the weight ratio of silicate to starch being in the range 10:1 to 1:50. It is preferred that the vehicle is a paint, especially a water-base latex paint. Fire resistant coating may be made on, for example, brick, expanded polystyrene, steel and wood. |
