Trapezoidal Foam Backer

Grip Strip is chemically inert closed-cell polyethylene that is shaped to fit between log courses to form a flat surface for the application of Perma-Chink or Energy Seal. This makes it easier to maintain a consistent thickness of sealant across the seam, reducing the amount of sealant required and improving the sealant's performance.
