Bond breakers are engineered products that form a membrane, allowing the surfaces to be separated easily. Reducing the amount of time needed to move loads, Ensuring surfaces are sprayed efficiently, The ability tore-use the form multiple times, Preserving thecharacteristics of the concrete surface, allowing them to be painted or modified using other architectural components, Allows and will not affect the adhesion of epoxy, adhesives and/or floor finishes. Because cracking occurs in the planes of greatest weakness, openings are particularly vulnerable. However, some designers incorporate shear transfer devices to limit the relative movement between thetwo panels on either side of a control joint, thereby reducing the stress on the joint sealant and providing longer life.

For further application instructions and contractor responsibilities and assurances, please contact the W. R. MEADOWS technical services department. In addition, walls with adequate horizontal reinforcement may not require control joints, as the reinforcement effectively reduces the width of shrinkage cracks. CAUTION: TO AVOID FOAMING, DO NOT MIX EXCESSIVELY. adjacent to corners of walls or intersections within a distance equal to half the control joint spacing.
