Caulking a Tub

Video, Kitchens and Baths, Painting, Interior Published 12/13/2006 by Danny Lipford

This plumbing trick is an oldie but goodie and works well when you need to caulk around the top of a tub. Scrape out the old caulk and fill the tub with water to weigh it down. If there is any flexibility in the wooden framing beneath, the tub will be at its lowest point. Create a guide for the new caulking by applying masking tape both to the wall and the top of the tub. Fill the gap around the tub with silicone caulking, let it dry overnight and drain the water.
