Expert Verdict — Reviewed by the SuperArbor Pro Desk
Always confirm the substrate is clean, dry and dust-free before priming, since adhesion failures usually trace back to surface prep. Use this primer wherever your Henry self-adhered membrane data sheet calls for a primer, and size the pail to the linear footage of flashing plus the primed field area. In cool or humid conditions allow extra cure time before membrane installation.
Use gloves and eye protection when handling primers, and follow the safety data sheet for ventilation and disposal requirements.
Order Henry 545 Aquatac Emulsion Primer in the 5-gallon pail for dependable adhesion under your self-adhered roofing system.
