ALFAPOL PU-3VM — matt UV-resistant water-based polyurethane sealer
Vapour-permeable matt water-based polyurethane sealer, resistant to ultraviolet, for cement and magnesia floors.

The Portland cement mix is laid with crushed chamotte to form a durable structural floor coating for forging, steelmaking, metal rolling and heat-treatment facilities. The concrete class by maximum permissible service temperature is I13, and the service range is −50 to +1300 °C. Compressive strength is at least 35 MPa, abrasion up to 0.4 g/cm², frost resistance F300, fire hazard class NG.
