The ARDEX MC™ RAPID Moisture Control System is a one-coat, 100% solids epoxy moisture management system formulated to suppress excessive moisture vapor emissions in new or existing concrete prior to installing an ARDEX underlayment with flooring. It is especially suited to treat areas of new concrete in critical installations, such as health care and institutional applications where the construction schedule does not allow adequate drying of the concrete. ARDEX MC RAPID is also recommended 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 be primed to receive an ARDEX underlayment in as little as 4 hours. The ARDEX MC RAPID system is based on a reactive epoxy that produces a hard surface and tenaciously bonds to the substrate. Once cured, ARDEX MC RAPID is able to reduce any level of moisture emissions to an acceptable level, even over new concrete that is only 7 days old. No sand broadcast is used for underlayment layers of 1/4’’ (6 mm) thick or less. For thicker applications, apply a second coat of ARDEX MC RAPID with a sand broadcast, or use the ARDEX MC™ PLUS Moisture Control System or the ARDEX MC™ ULTRA Moisture Control System.
