Existing interior concrete slabs that suffer from recurring moisture and mold problems can be permanently repaired by installing the Barrier-1 topical system. This three-step process creates a chemical seal preventing moisture intrusion from hydrostatic pressure and capillary action. A microbial additive inhibits any potential mold growth.
The Barrier-1 topical system is a three-step process that densifies and totally reconditions the concrete floor surface. The initial step involves cleaning and bead blasting the surface to remove any prior finishes or surface sealants. The second step includes a low-pressure application of two coats of the Barrier-1 sealant at the rate of one gallon per 250 square feet. In the final step, a cementitious coating is installed to create the final permanent seal.
The system has zero VOCs (volatile organic compounds) and is factory installed. The Barrier-1 topical system can assist a project registered under the U.S. Green Building Council’s LEED rating system by qualifying for possible credit points in the areas of Energy & Atmosphere, Materials & Resources, and Indoor Environmental Quality.
