KRASKO

Proteksil-2MS — two-component polyurethane primer-impregnation

Concrete impregnations and hardeners

This two-component impregnation with an aliphatic hardener penetrates concrete up to 10 mm, dustproofs it and increases adhesion and water resistance. It is used as a base coat under Polimerstoun-2, Polimerstoun-2 SLIM, SLIM (UV) and Teksipol-2 Ekspert “Bystry Pol”, and indoors with low-intensity use as a standalone coating. The pot life of the mix is at least 6 h, recoat drying 60 min.
