Seal tough jobs
in a flash.

ZIP System Liquid Flash

Create an air- and watertight seal over rough openings.

Made with a high-performance technology consisting of silicones and urethanes, ZIP System liquid flash makes it easy to create a powerful seal over irregular shapes and surfaces, such as window openings and pipe penetrations, using a fluid-applied flashing. Using a trowel or paintbrush, apply ZIP System liquid flash over gaps up to ½" to immediately waterproof your project and get a fast rough dry-in — even in wet weather. Available at local lumberyards.
