Expert Verdict — Reviewed by the SuperArbor Pro Desk
Keep a pail of this cement on the truck for emergency leak response, since it bonds to wet surfaces and even under water when drying is not an option. For permanent flashing details, embed fabric reinforcement as the manufacturer's system details direct and plan for the Intermediate Grade 3 gal size on larger repairs. Verify chemical compatibility with the specific membrane before large-scale use, as the source notes compatibility with most APP and SBS membranes. Follow solvent-bearing cement handling practices and local VOC rules.
Contains solvents; keep containers away from open flames and follow the safety data sheet for ventilation and handling.
