ALFAPOL PU-1 — deep-penetrating polyurethane impregnation for concrete

Concrete impregnations and hardeners

The one-component polyurethane impregnation penetrates deep into concrete, strengthens the substrate and improves its chemical resistance, water resistance and the adhesion of subsequent layers. It is applied in two or three coats; works are permitted from as low as +5 °C and substrate moisture up to 5%. At +20 °C foot traffic is possible after 12 hours, bond strength to concrete is at least 2 MPa, and service is from −30 to +50 °C.
