The tapers are typically either 45 or 22.5 degrees. Colors: Stone Gray, Desert Tan and Dura-White. Bond breakers allow for differential movement between the precast concrete backer and the stone veneer, helping prevent staining and cracking of the veneer. The bond breaker reported to have been used on the casting slab was a chemical reactive organic curing agent and bond breaker (without wax or hydrocarbon resins). Bond breaker tape is black polypropylene tape that provides an option to break the bond of the sealant between the joints between the surfaces of the concrete. Concrete expands and contracts with temperature and moisture changes. SPEED-E-JOINT consists of two solid pieces that have been pre-assembled for easy handling and installation. CERAMAR is compatible with all currently popular cold-applied sealants, caulks, and hot-pour joint sealing compounds. Whenever a casting of the slab is done, it requires an adequate quantity of water, so that the chemical reaction between cement and water can progress uninterruptedly.
