Expert Verdict — Reviewed by the SuperArbor Pro Desk
Primers are frequently the difference between a self-adhered membrane that holds long-term and one that peels at the laps - always prime porous or dusty substrates. Verify coverage and application temperature ranges against the GCP product data sheet before bidding, since porosity of CMU, concrete or sheathing will change actual consumption. Pair with Perm-A-Barrier membranes for the full air barrier assembly.
Follow the GCP safety data sheet and product data sheet for handling, PPE and application conditions; ensure adequate ventilation during use.
Order GCP Perm-A-Barrier WB water-based primer, 5 gallon pail, to prep your substrate for air barrier membrane.
