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.
