PUR 220 UV is a two component, aliphatic polyurethane based, interior and exterior top coat for concrete and metal surfaces, low viscosity, UV resistant, featuring a glossy surface appearance, self levelling varnish.
Preparation of Substrate
The application surface must be durable, dry, clean and clean off materials which prevent bonding, such as dust, oil, rust and remove loose pieces. The residual moisture content of the substrate must not exceed 4%. Big pores and cracks should be repaired with suitable BAUMERK repair mortar. Surface preparation completed concrete surface should be primed with appropriate BAUMERK primers and epoxy or polyurethane application should be done, then PUR 220 UV will be ready for final coat application.
Application
Prior to mixing, stir part A and B separately with a mechanical drill at a very low speed. B component is poured into A component under low speed mixer, they are mixed together during 3 minutes until there remains no lump, getting homogenous mixture. After the mixing, prepared mixture can be applied on a surface, which is already primed with appropriated BAUMERK primer, with a brush, roller or spray gun.
