Application instruction

Install backing material or joint filler, setting blocks, spacer shims and tapes. When extruding the sealant, cut the nozzle to the desired width, cut the tip off the cartridge, and apply the sealant firmly to ensure good contact between the sealant and the substrate. Before the sealant has skinned, tool it off to ensure a good finish, and to improve the wetting out of the sealant to the substrate. Wipe off the excess sealant with clean cloth and polyethylene scraper. Masking tape can be used and must be removed before the skin over starts.
