Joint faces should be clean, dry and free from dust, oil, grease, old sealant and any traces of contaminant which may affect adhesion. Any previously applied sealant must be mechanically removed. Movement joints should be back filled with a foam backer rod such as FGT BR135 in order to control the depth of sealant and prevent three-sided adhesion.
