The matt modification of the Lyuks varnish removes the gloss from polyurethane and epoxy floors and at the same time serves as a transparent UV-resistant protective film. The varnish is applied in two coats with a velour roller, rolling in mutually perpendicular directions, and porous substrates are primed beforehand until the pores are closed. Film tensile strength is at least 40 MPa, Shore D hardness 70–74, service temperature from −60 to +100 °C; the varnish is permitted for healthcare institutions and food plants.
