Your go-to moisture vapor barrier and primer is XL Brand’s DriSeal MOISTURE MAX. It makes flooring prep fast, simple, and worry-free. With rapid drying, zero VOCs, and no mixing required, it’s built to save you time and hassle — while delivering serious protection against moisture and alkalinity.

DriSeal MOISTURE MAX is a water-based, one-component system formulated to reduce substrate moisture-vapor emissions, prime floors prior to the application of underlayments, and block concrete alkalinity prior to the installation of floating floors or resilient flooring. DriSeal MOISTURE MAX enhances the speed of flooring installation via fast drying RapidCure® Technology and by combining multiple steps into one product.

DriSeal MOISTURE MAX meets ASTM F3513-24 for single component, fluid-applied barrier-forming moisture mitigation systems for use under resilient floor coverings.
