Before construction, thoroughly clean the joint base surface to remove dust, oil stains, accumulated water and old sealant, and make it completely dry. Fill overly wide gaps with foam filler in advance. Stick masking tape on both sides of the joint for neat sealing lines, load the sealant into a caulking gun and cut the nozzle at an angle. Apply the sealant evenly at a steady speed to fully fill the gap, then smooth the sealant surface with a wet scraper and tear off the masking tape immediately. Avoid water contact and touching within 24 hours at room temperature, and wait 7 days for full curing before normal use.
