Expert Verdict — Reviewed by the SuperArbor Pro Desk
As the base ply of the HydroStop liquid-applied system, this coat is applied with Premium Fabric embedded at laps, seams and flashing details, then finished with the matching top coat. Confirm substrate compatibility and preparation before application, and choose the winter grade when jobs must proceed in cooler weather. Order base coat and top coat quantities together so coverage rates stay aligned across the system.
Follow the manufacturer's safety data sheet and jobsite fall-protection requirements when handling and applying roof coatings.
