Bond breaker tapes: best-selling items
Bond breaker tapes are a specialty construction product used to extend the lifetime and durability of water-proof sealants. When applying sealant to a corner or "fillet" joint, using bond breaker tape to line the join where the surfaces meet protects the sealant from excessive stress. Bond breaker tape is one of the "secret weapons" of construction professionals who realize that the vast majority of corner joints are never properly sealed. And that means leakage is just a matter of time.
Despite its utility in strengthening seals, bond breaker tape isn't widely known of or used properly. This is a huge issue for homeowners -- not only because of the drips and puddles and water damage that inevitably follow a seal that isn't weather-proof. The casual handyman will run another bead of silicon caulk over the corner joint and congratulate himself for a job well done. And that may even work, temporarily... But inevitably the joint will move from the constant expansion and contraction of the home, the seal will fail, and the leak will return.
Bond breaker tape plays a critical role in a durable, long-lasting seal. You simply can’t use a backer rod to mechanically support a sealant joint the way you can a tape or membrane. Only the sealant's adhesion to the surfaces comes into play. Unfortuantely, corner joints experience the most stress of all joint types under even the slightest movement.
Whether you're sealing a window, weatherproofing a home, or installing a shower cabinet, bond breaker tape vastly improves the lifetime of the finished waterproof seal. These tapes are constructed of extremely tough polyethylene for extended lifetime and durability. The adhesive side bonds well with structural steel, tile, and a wide variety of other construction materials. A wide variety of sealants bonds readily to the tape's surface. Tolerates extremely high and low temperatures.
