Excellent stability; does not require continuous mixing throughout the application; the material must be mixed only prior to application. At other points of wall stress concentration, control joints are used to effectively divide a wall into a series of isolated panels. When a bond breaker is needed at a construction joint, a curing compound, form release agent and the like can act as a bond breaker. They are essentially vertical planes of weakness built into the wall to reduce restraint and permit longitudinal movement due to anticipated shrinkage, and are located where stress concentrations may occur. <<2F6130032B3F7D4E822F4C36175224FC>]/Prev 134655/XRefStm 1837>> Sealant Compatible: Works with common sealants.
