Recaulking tub?

Question

When recaulking my tub, how much weight do I need to put in the tub for proper sealing?

Answer 1

I use a few concrete blocks or whatever other waterproof weight I have, plus filling the tub with water. This is only necessary for plastic, fiberglass or acrylic tubs, not cast iron or steel since these don't flex.

Answer 2

Fill the tub with water.

Answer 3

just fill the tub full of water

Answer 4

If the tub moves at all something is not right.  Caulk will not hold a tub in place.  If you are recaulking where you removed old caulk you should not have an issue.
