Expert Verdict — Reviewed by the SuperArbor Pro Desk
Primer is the difference between a Peel & Stick splice that holds and one that lifts: stir thoroughly, apply a thin uniform coat, and wait until it flashes off tacky before laying tape. A 1-gallon can suits small repair work, while the 3-gallon can is more economical for large flashing runs. Check the date on older stock since the 12-month shelf life is enforced in the spec.
Solvent-based primer is flammable; keep containers closed, ventilate the work area, avoid open flames, and wear gloves and eye protection.
Prep black EPDM correctly with GenFlex GenPrime EPDM Primer in 1 or 3 gallon cans.
