Preferably, additional substances are included in the composition, such as silane to aid adhesion and powdered additives to inhibit burning and to minimise smoke production under fire conditions. A method of making a paint composition comprising adding sodium silicate, hydrochloric acid and water to aqueous sodium silicate followed by adding a powder containing one or more frits is also claimed.
