A one-coat, fast-track 100% solids epoxy moisture control system formulated to suppress moisture vapor emissions in new and existing concrete prior to installing ARDEX Americas Underlayments. Product Capabiltiies: Use to treat areas of new concrete that may still be damp or have very high (100% RH) moisture readings. ARDEX MC™ RAPID is also used over existing concrete where the level of moisture emissions from the slab exceeds the maximum allowed by the manufacturer of the finished floor covering. Designed specifically for fast-track installations, ARDEX MC RAPID can receive an ARDEX Americas Underlayment in as little as 4 hours and is approved with the use of finished flooring, including roll goods and sheet flooring. The ARDEX MC RAPID system is based on a reactive epoxy that produces a hard surface and tenaciously bonds to the substrate.
