While some caulk can only be applied in warm weather (40 to 80 degrees Fahrenheit), certain rubber or silicone caulk can be applied in weather as cold as -20 degrees Fahrenheit.

New Caulk Over Old Caulk It's not always necessary to remove old caulk before applying new. You can apply a wider bead of new caulk, which covers the old bead and sticks to the uncaulked surfaces on both sides. (If oil is still lingering on the old caulk, new caulk won't stick.)Do you need to fill the tub with water before caulking?
Filling the Bathtub with Water When you are caulking the bathtub, fill it three quarters of the way with water. Applying the caulk at these pulled seams will allow it to dry in a position where it will not crack once the bathtub is being used again.What happens if you get caulk wet before it dries?
Over time, moisture can erode even the best sealant, allowing mold and mildew to form. Despite bleach and scrubbing, dinginess can persist, so replacing the caulk is a smart move.What happens if silicone sealant gets wet before it cures?
Freshly applied silicone caulk has to seal before you use the shower, and moisture in the air speeds the curing time. Even if the silicone no longer feels tacky, it may not be fully cured. If the air is dry, it may take as long three days before the caulk is cured, according to remodeling expert Tim Carter.How thick should caulk be?
A general rule of thumb to follow when caulking is to make the joint half as deep as it is wide. This means on a 1 inch caulking line, the depth should be 1/2″ deep (or thick). The joint depth should never be thinner than 1/4″ and never thicker than 1/2″.How long will Silicone last?

How long should shower dry before caulking?
You should wait at least 24 hours for the new caulk to cure before using your shower.How do you know if caulk is cured?
Silicone caulks have an expiration date. If the caulk is out of date, it may never cure. If in doubt, test a bit on a nonporus surface to see if the caulk gets rubbery and pliable after 24 hours.How do you speed up caulking to dry?
If your caulk is acrylic latex, it dries as water evaporates from the caulk, so placing a fan in the room to blow on it will speed the drying process. If your caulk is silicone, it needs moisture in the air to dry, so placing a humidifier in the room should speed the drying process.How long should silicone dry before adding water?
I would wait at least 3 days before adding water. IF you add water sooner, then chemicals in the silicone may leach out and stay in the water even if you don't plan to put fish in for a few weeks. Also, the silicone may become weak with water contact.
