A single material serves as both primer and finishing enamel: it is applied to prepared concrete in two or three coats by brush, roller or spray. It is available in gloss, semi-gloss and matt versions in RAL colours. At 20 °C the gloss and semi-gloss coatings withstand 720 h of water, AI-92 petrol and 5 % hydrochloric acid; for harsher chemical conditions the enamel is laid over KHIMTRAST Grunt EP primer.
