ALFAPOL PU-1 — deep-penetrating polyurethane impregnation for concrete
One-component polyurethane primer-impregnation that strengthens concrete and improves its chemical and water resistance and the adhesion of coatings.

Crushed granite of 5–10 mm fraction and a cement dry mix are the two components of the VB finished concrete floor for workshops, warehouses, car parks, wet rooms and open areas. The coating reaches at least 50 MPa in compression, with abrasion no more than 0.4 g/cm², water resistance W16, frost resistance F400 and combustibility class NG. Laying is permitted from as low as +5 °C, site foot traffic after 10–12 hours, service from −50 to +50 °C.
