Expert Verdict — Reviewed by the SuperArbor Pro Desk
One-component liquid flashings like SmartFlash ONE save time at window openings, pipe penetrations and transitions where sheet flashing is hard to form. Apply to clean, dry, primed substrate within the manufacturer's temperature window and build to the recommended wet-film thickness. Keep the can sealed between uses since one-component products skin over in the container.
Apply in a well-ventilated area and follow the manufacturer's safety data sheet precautions for skin, eye and solvent exposure.
Order CertainTeed SmartFlash ONE 1 gallon liquid flashing for reliable detail sealing on your next barrier job.
