Akvastoun-2MS — water-polyurethane primer-impregnation for concrete
Odourless water-polyurethane primer-impregnation for old, friable and damp concrete; penetrates the substrate up to 10 mm.

“Bystry Pol” (Fast Floor) solves two tasks at once: it fills damage in an old concrete substrate and at the same time forms a seamless wear-resistant coating indoors. Reinforcing additives and the polyurethane binder give an elongation at break of at least 75 % to ISO 527 and a Shore D hardness of 70. The compound has no unpleasant odour, is resistant to chemicals, fuels and lubricants, abrasion and vibration, and suits production halls, warehouses, food and pharmaceutical plants, schools and medical facilities.
