I recently did some patch work on my bathtub caulking. Just a little to give it a few more months before I redo the entire bathtub. My tub is floating and has a tub surround.
My wife usually removes the caulk during the day and she prefers that I do the actual caulking as I am better at getting a good bead size.
One of the steps she does to prepare the scene for me is full the bathtub all the way with water for what she says "so the caulk wont pull away". My personal problem comes from the tub water was not full and I did the patch work. My wife was against that and insisted that I fill the tub and start over. To make all parties happy I did just that.
What am I accomplishing by filling the tub with water? The weight from that does not reflect the weight that will be in the tub (estimation alert) 95% of the time. If filling the tub with water is beneficial why all the way?
Most of the instructions I ran into make no mention of filling the tub with water at all.
