Expert Verdict — Reviewed by the SuperArbor Pro Desk
Asphalt primers like Mule-Hide 121 are a standard prep step on aged or porous surfaces before applying plastic or asphalt cements and coatings. Apply a thin, uniform coat and let it dry to the tack condition recommended by the manufacturer before over-coating. Use the aerosol for flashings and small repairs and the 5-gallon drum when priming large field areas.
Asphalt primers contain solvents and are flammable; provide ventilation, keep away from ignition sources and follow the label safety directions.
Order Mule-Hide 121 Asphalt Primer in a 14 oz. can or 5-gallon drum for your next roofing prep job.
