Seal Roofing Seams and Fasteners with Confidence
Phoenix’s Fastener & Seam Sealer is a high-viscosity, self-leveling elastomeric sealant designed to fill gaps, cracks, and crevices around roofing fasteners, seams, penetrations, and flashings. It provides a durable, watertight foundation essential for the Phoenix Liquid Applied Commercial Roof System.
Unlike many thick coatings, Fastener & Seam Sealer is sprayable, allowing for easy and efficient application. Each gallon covers between 32 to 160 linear feet, depending on the spray pattern width and desired wet mil thickness.
For complete application details, consult the Fastener & Seam Technical Data Sheet.
