BOND BREAKER TAPE

For seam preparation when re-caulking.

Three-sided adhesion will limit the amount of movement that a seam can accept before failing. TDS recommends applying bond breaker tape at the base of every seam to create two-sided adhesion, which allows the sides of the the seam to work independently from the bottom, increasing flexibility.

The bottom of the caulk seam should be able to move at the base of the seam as the deck flexes and works.
