In fact, some types of joint fillers can serve as a backing material and bond breaker, in which the applicator can apply the sealant directly on the filler. They are also used to resists shrinkage cracks, which may appear on the concrete during casting, due to the unexpected evaporation of water from the concrete surface. German engineers have been successfully using non-woven geotextiles as bond breakers for decades. TILT-CRETE concrete cure and bond-breaker is a new, innovative, unique formula of proprietary, reactive organic materials in an aqueous dispersion.

Bond breakers are normally used on tilt-up walls and precast segments to ensure the right pieces are cast together. If, after application of the bond-breaking coat, steel, or concrete-placing operations are delayed longer than two weeks, the bond-breaking coat should be inspected carefully to determine if it still provides 100% coverage. EQc2: Low-Emitting Materials [For Healthcare and Schools (exterior-applied products) ONLY]. A bond breaker should always be used between concrete pavement and cement treated base. Due to its unique self-sealing characteristic, no subsequent joint sealing is required. TILT-CRETE is used as a cure and bond-breaker in tilt-up, lift-slab, and precast concrete construction.
