KRASKO

Akvastoun-2MS — water-polyurethane primer-impregnation for concrete

Concrete impregnations and hardeners

The impregnation is thinned with water, is applied to concrete with residual moisture up to 15 % and does not require production to stop, so it is used in shopping centres and in medical and educational facilities. The compound strengthens and dustproofs the substrate, seals pores and provides antiseptic protection, and thanks to its weather resistance it also works on open areas. In a system with Betostoun-AKVA water-polyurethane enamel the service life of the coating exceeds 5 years.
