Mironit-Metall fire-protective plaster for steel structures (KrilaK)
Sprayable mineral mix for fire protection of steel structures, R up to 240 including hydrocarbon fire, for unheated structures.

Attik protects timber and timber-based materials indoors against both fire and mould fungi. It is a colourless, odourless aqueous solution of inorganic salts; it is also supplied as a dry mix. Per NPB 251-98, two coats give fire protection performance group I, one coat group II. The product is applied by spraying, roller, brush or immersion, and treated timber may subsequently be painted; packaging is a 20 l plastic container.
