It is 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). Two coats are required to fully seal the substrate; and it quickly dries in 3-4 hours. Once dry, this product doesn’t require a primer before the application of TEC® surface preparation products.
