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.

   At what point do you remove the Masking Tape? If you wait till the Caulk is dry, doesn’t it pull it up?
   Thanks,
