Expert Verdict — Reviewed by the SuperArbor Pro Desk
Use a detail caulk like this only where the roofing system specification calls for it, such as terminating flashing edges and sealing membrane cement splice edges. Keep a cartridge or two on the truck for single-ply detail work. For jobs requiring a different shade to match the membrane, black or white variants are available in the same line.
Wear gloves and eye protection when cutting cartridge tips and dispensing sealant, and follow the product safety data sheet for ventilation and handling precautions.
