KHIMTRAST PU varnish — gloss polyurethane sealer for polymer floors

Sealers and topcoats

PU varnish is applied to a polymer floor no earlier than 24 h after the floor is laid, in one or two coats, by brush, roller or spray. The clear film gives a gloss of 90–98 %, protects against UV and resists abrasion well — Taber abrasion not more than 20 mg per 1000 revolutions. Foot traffic is allowed after 24 h, impact and vibration loads after 3–5 days; the varnish is also used to protect metal.
