How long should I leave the removable capping in place before removing it?
It is best to leave the removable capping strips and rebate moulds in long enough for most initial shrinkage to occur. This places less stress on the sealants and permits them to adhere better to the drier concrete surfaces. Prior to applying any sealants, the joints should be cleaned and primed to the sealant manufactures specification. The use of a “backing tape” is recommended to prevent the sealant adhering to the bottom of the sealant void.
