OVERVIEW

PorousPrep brushes on easily and efficiently, and its glue-like viscosity reduces rundown and potential for spills. PorousPrep usually dries in 30 to 60 minutes when applied to dry surfaces. Use R-Guard PorousPrep as part of a continuous, building-wide air barrier system, or to complement conventional waterproofing or air barrier components.
