urethane modified concrete (UMC) primer / sealer

Kraftig SC is a urethane concrete primer and sealer designed for use with Kraftig TG (trowel grade) or Kraftig SL (self-leveling) urethane modified concrete products. It also refinishes old and abused urethane-coated floors.

Kraftig SC is a urethane concrete primer and sealer designed for use with Kraftig TG (trowel grade) or Kraftig SL (self-leveling) urethane modified concrete products. It also refinishes old and abused urethane-coated floors.

Kraftig SC consists of polyurethane resin, resin hardener, and a blend of Portland cement and aggregates. A color pack is also included if requested.

As a primer, Kraftig SC reduces the potential for pinholes in various UMC systems. As a topcoat, it is suitable in heavy-duty applications such as restrooms/lockers, kitchens, cafeterias, equipment maintenance areas, laboratories, manufacturing facilities, processing areas, bottling/packaging areas, and other areas requiring a chemical resistant, sanitary, high impact, solid color finish.
