Expert Verdict Reviewed by the SuperArbor Pro Desk

Water cut-off mastics are used to block moisture paths inside a repair before the membrane patch or flashing goes on, and they work best tooled into a continuous bed with no skips. Clean and dry the substrate first so the mastic bonds rather than trapping water. On exposed areas, confirm the detail permits leaving the mastic visible or requires a top sealant.

Follow the label and safety data sheet instructions and wear gloves and eye protection during application.
