Expert Verdict — Reviewed by the SuperArbor Pro Desk
Seal every membrane lap, screw penetration and termination with this butyl caulk while installing RainEscape; it is what keeps the drainage plane watertight. Apply to clean, dry surfaces and work the caulk into the lap before stapling. Keep a couple of cartridges on hand for mid-install touch-ups even on small decks.
Use in a ventilated area and follow the safety directions on the cartridge label; keep sealant off finished surfaces as butyl residue can be difficult to remove.
