Caulking a Tub

This plumbing trick is an oldie but goodie that works well when you need to caulk around a tub. Here’s how to go about it:

  • Scrape out the old caulk or grout around the tub.
  • Fill the tub with water to weigh it down.
  • Apply masking tape to both to the wall and the top of the tub, leaving a gap for the caulking.
  • Fill the gap around the tub with silicone caulking, and smooth it out.
  • Allow the caulking to dry overnight before draining out the water.
