LEVL Coat 161 — polyurethane hardening impregnation for concrete

Concrete impregnations and hardeners

LEVL Coat 161 one-component polyurethane impregnation cures with air moisture and is supplied ready to use. It hardens the top layer of porous low-strength substrates, on its own or as preparation for polymer coatings. Work is possible at air temperatures down to −10 °C (curing slows down in this case), and the finished coating is used from −60 to +60 °C. Two coats are applied by brush, velour roller or airless spraying; packaging: 19 kg pail and 220 kg drum.
