Expert Verdict — Reviewed by the SuperArbor Pro Desk
On EPDM repair and flashing work, priming pressure-sensitive areas properly is the difference between a seam that holds and a callback. HP-250 saves time by combining cleaning and priming, but coverage drops on dirty or chalked surfaces, so plan pail quantities with some margin. Keep it with your SecurTAPE and FAT inventory so crews are never tempted to skip the priming step.
Solvent-based products require adequate ventilation, and open flame and smoking should be kept away during application per the manufacturer's safety directions.
Order Carlisle Sure-Seal EPDM HP-250 Primer to get reliable adhesion from every pressure-sensitive EPDM accessory.
