In this scenario, TILT-CRETEs resistance to rain is highly reduced. Easy-Lift FD is applied to the concrete casting slab to efficiently prevent the bonding of subsequent concrete pours. Some designers use 1-1/2- inch deep reveals but it is important to remember that the reveal strips reduce the effective structural depth of un-insulated panels. SPEED-E-JOINT Bond breakers are used to break the bond between the substrate and the waterproofing membrane, forming an adjustable bridge, which resists the movement of water or moisture.

Now, bond breakers are being used more and more in construction."}}]}. For both the curing and bond-breaking applications, once TILT-CRETE is sprayed on the surface, do not track over the slab until the surface is totally dry to touch. Most bond breakers are designed to provide curing compounds to the top sides of casting slabs or molds and precast members. TILT-CRETE is not recommended to be used with any other manufacturers bond-breakers. SDS. Bond breakers are used on concrete surfaces to reduce the cracking of slabs due to fluctuations in temperature and humidity. In addition, it helps to avoid cracks in some applications such as tilt wall panels. Water-based indicates that water is the main contributor to the bond broker.
