Questions & Answers
If its expiration date has passed, I would not use it. Caulk that has been around for a while loses its adhesion faster it's better to replace it. It is by far the best stuff you will ever use. There is a six-hour waiting period for the batch to sit We recommend that water be exposed to in the bath or kitchen, or if you want paint anywhere else, 7 days before use.
In all cases, a cured bond break will exist, but if you need to increase the fill of the caulkable gap, no harm will be done. A little acetone can be used to react the existing caulk. You should not use vertical fill if it's in a vertical direction! Your hands will be a mess and everything else will be a mess too.
As far as I can tell, I haven't used it that much, but this caulk seems very durable and sticks to anything well.
