For the best results, use a caulk gun to apply the caulk in a smooth, uninterrupted line. Once the caulk is in place, use your finger or a putty knife to smooth it out. Finally, allow the caulk to dry for 24 hours before painting or staining.
Paint-ready: Most caulk is ready to be painted in two to four hours. However, it has not fully dried through by this time. Fully cured: In 24 hours, caulk is fully cured.
The paint will not adhere well to the caulking and will likely peel off soon after you finish painting. Plus, you'll end up with an uneven appearance where the caulking is located.
Always caulk before painting, and wipe as much off as possible with a damp cloth before letting it dry,and it's better to do the day before painting so it doesn't get cracks,when painted over.

The very short answer is, “No, you cannot paint over silicone”.
Silicone caulk is the most commonly used option for bathrooms, with a quick drying time of about 30 minutes to an hour. This type of caulk bonds well to nonporous materials, like glass or metal, though it takes about 24 hours to fully cure.
There are two main issues with caulk: Cracking - caulk is unfortunately prone to cracking, which sometimes occurs when the caulk is not flexible enough for the surface it is filling. Crazing - when paint is applied over caulk, it can sometimes lead to the paint to peeling & flaking.
Finally, caulk any areas where the trim meets another piece of trim or another type of surface. Once you're finished caulking, smooth out the caulk with your finger or a putty knife, and then allow it to dry completely before painting.
Ensure Caulk is Cured and Dry
Silicone sealant dries in 30-60 minutes, reducing the risk of smudging or damage to the caulk's surface. However, that is just dry to the touch. You should always wait at least 24 hours before attempting to shower after a caulk installation.
Typically, you'll have to choose between latex, which is paintable and easy to tool, and silicone, which has good adhesion and water resistance.
Applying paint over a partially dried bead of caulk. The paint dries first, forming a film. As the caulk dries, it shrinks and causes the paint film to stretch and crack.
Typically, the caulk will be touch dry within an hour, meaning dust and debris won't stick to the surface. Give it another couple of hours before you think about applying any paint. Ideally you want to leave the caulk for 24 hours to allow it to fully cure.
Touch the silicone lightly with a clean finger. If it feels tacky or sticky, it is not yet fully cured. Fully cured silicone should feel dry to the touch.
Clean up excess wet caulk with a damp sponge before it skins over. Excess dried caulk must be cut or scraped away. 7. Allow caulk to dry at least 2 hours (longer in cool or humid conditions) before painting with latex or oil-based paints.
How long before you can paint over decorators caulk? Most caulks state that they can be painted or sprayed over in 1-2 hours. However, if you aren't in a rush, we'd give the caulk 24 hours to dry. This allows it to dry completely and really fill in the crack.
Caulk Bead Cracking
When caulk is applied to unprimed new wood, that wood will wick moisture from the caulk while the caulk is trying to cure. The moisture imbalance will prevent the caulk from coalescing properly, resulting in a cracked or separated caulk bead.
For painting purposes, a quality latex caulk or siliconized latex caulk is the best choice. Sometimes referred to as "painter's caulk", these caulks are ideal for sealing interior windows, doors, and trim, and for filling small cracks and holes in drywall or baseboards.
The new caulk will shrink a bit as it dries (which is why it's always important to let it fully dry before painting over it), but it forms a seal that will keep moisture out and make structures more air tight and durable.
Go to a home improvement center or paint shop and look for the spray cans of primer. Buy a can that says it is a shellac spray primer for any surface. Shellac spray primer will stick to just about anything, so it is the best primer to use to cover up silicone caulk to get it ready to paint over.
Expect caulk to take at least 24 hours to cure, though some formulas will require up to 12 days under certain conditions. Curing is the slower, more complex process that begins once you expose the caulk to oxygen.
The initial silicone dry time may only be 30 minutes to an hour, but at this point, the silicone is only dry to the touch. The full cure time for silicone is usually around 24 hours but could also take several days.
Poor Ventilation. Poor ventilation can also contribute to silicone caulk not drying. Proper airflow is essential for the evaporation of solvents in the caulk, which is a crucial step in the curing process. Without adequate ventilation, these solvents can become trapped, causing the caulk to remain soft and sticky.
There is no way to necessarily speed up the curing time; however, you can optimise the surrounding conditions to allow the caulk to cure efficiently. Silicone based caulks react with moisture in the air to cure, so implementing a humidifier can help to increase the humidity, creating ideal conditions for curing.
