PROSOCO R-Guard PorousPrep - 1 Gallon


R-Guard PorousPrep seals the dry, cut edges of gypsum wall boards exposed in rough openings for windows and doors. The sealed edge makes a perfect surface for easy application of R-Guard Joint & Seam Filler or R-Guard FastFlash®. 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.

  • Ensures application of Joint & Seam Filler or FastFlash® to dry cut edges of gypsum wall board is fast and efficient
  • Glue-like viscosity makes application smooth and easy, while reducing potential for spills and rundown
  • Water cleanup
  • No solvent odor
  • Treated surfaces “breathe” – does not trap moisture
