Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose trowel grade when you need to build thickness or fill on flat work; the self-leveling tube and bucket grades suit smaller penetrations and seams. Reinforce penetrations, curbs and seams with GAF Premium Fabric embedded in the sealant for added durability. Always confirm the existing membrane chemistry first, since this sealant must not go over silicone.
Solvent-based sealants release vapors: use in well-ventilated areas, keep away from ignition sources, and follow the label's safety directions.
Order GAF RepairPro Sealant in the 3-gallon trowel-grade pail for your next repair or maintenance call.
