Expert Verdict — Reviewed by the SuperArbor Pro Desk
Prime porous or dusty substrates such as concrete and gypsum before applying self-adhered vapor retarders to achieve reliable bond. Apply at an even film with brush or roller and allow proper dry time before membrane installation. Order pail quantity based on substrate porosity and the GAF SA system's specified application rate.
Solvent-based primers release flammable vapors; ensure ventilation, keep ignition sources away, and follow the product safety data sheet.
Order the 5-gallon GAF SA Primer to prep substrates for your GAF SA vapor retarder installation.
