A newly released liquid flashing from GCP Applied Technologies Inc. (Cambridge, MA) is made to take care of difficult detail areas, and make the application of flashing more efficient.

Perm-A-Barrier liquid flashing provides a seal equal to that of a traditional flashing, the company says, and dries at 20 mils.

Perm-A-Barrier liquid flashing is a fluid-applied, one-component flashing product that the manufacturer recommends for use around door and window openings, counterflashing waterproofing and air barrier membranes and preventing building envelope deterioration.

Low-Temperature Application

Perm-A-Barrier liquid flashing is solvent- and isocyanate-free, according to GCP, and has a VOC content of 10 g/L. It can be applied at temperatures as low as 35 degrees Fahrenheit, according to its product data sheet, and can be applied to damp-to-the-touch substrates, though application when conditions are expected to be cold and damp for an extended period is not recommended.

The product provides a seal equal to that of a traditional flashing, the company says, and dries at 20 mils.

Perm-A-Barrier Line

The liquid flashing product is one component of a line of Perm-A-Barrier products that range from air barriers to aluminum flashing, and is compatible with other products in the line.

Perm-A-Barrier liquid flashing is available in 20-oz. sausages, and is to be applied with a caulking gun, and spread with a trowel, joint knife or other hand tool.

GCP Applied Technologies was formerly Grace Construction Products.
