Control the Moisture
Avoid using heat to speed up the silicone caulk drying process, as it can soften or melt the caulk. If you’re using acrylic latex caulk, setting up a fan in the area can help speed up drying and curing. That’s because water evaporating from this type of caulk is what makes it dry and cure.

What’s the difference between caulk and silicone?
Caulk makes your surface airtight and watertight. Silicone sealants, on the other hand, remain flexible for years which make them ideal for areas that are prone to expansion and contraction. Silicone has strong binding properties that can be applied to almost any surface both indoors and outdoors.
