Moisture Vapor Barrier - PROFLEX® HYDRA-STOP

PROFLEX® HYDRA-STOP is a one component moisture vapor barrier product formulated to be applied to damp or new concrete, as little as 48 hours old with a moisture vapor emission rate (MVER) less than or equal to 25 lbs. per 1,000 ft2per 24 hours (0.12 kg/m2 per 24 hours) or a maximum relative humidity of 100%. It is also designed to reduce the MVER from 25 lbs. to 3 lbs. per 1,000 ft2 per 24 hours (0.015 kg/m2 per 24 hours). HYDRA-STOP is colored green for visual assurance of coverage during the application process. Two coats are required to fully seal the substrate; and it quickly dries in as soon as 3-4 hours. Once dry, this product doesn’t require a primer before the application of PROFLEX® surface preparation products. HYDRA-STOP is a moisture vapor barrier for the installation of floor coverings, tile and stone. Ideal for use with other PROFLEX® adhesives, patch, underlayment, leveler and mortar products.
