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 choice of caulking depends on the project, but silicone, acrylic latex, and polyurethane are commonly used by professionals due to their durability and flexibility.
Using Acrylic-Latex Caulk
The most significant advantages of acrylic-latex caulk are that they are easier to clean up and paintable when the job requires it. Acrylic-latex caulks dry quickly and is often inexpensive.

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.

Quick answer: Don't caulk the weep holes, moving portions, or the tops of your windows.
Why does paint not stick to silicone sealant? This may sound like a simplistic answer, but silicone is designed so that nothing will stick to it. With its waterproof characteristics and extremely smooth finish, the paint will not adhere well enough for it to last.
You also need to consider if you will be painting over the caulk, because caulk made with silicone does not provide a suitable adherable surface, which is why it needs to be primed before being painted.
In order to fix this problem, you may need to use a different type of caulk or even just apply a wider bead of caulk. Similarly, it's not uncommon that the gap isn't wide enough. In this case, you may need to use a thinner bead of caulk or even just apply more pressure while smoothing it out.

Cut the Caulk Tube at the Right Angle
This angle creates a small opening that allows for more precise application and better control over the flow of caulk. Additionally, cut the tip to match the size of the gap or joint you are caulking, ensuring that the bead of caulk fills the entire space without excess.
“You are putting it on the edge of the exterior trim to the outermost part of your window on the outside.” And then caulk the outer edge of the window frame on the inside of the house. “You usually put it on both sides for double coverage.”
DO NOT CAULK the space between the panels and the J-channel, outside and inside corners and any other trims. Do not caulk overlapping joints between siding panels. NEVER NAIL THROUGH THE FACE OF THE SIDING!
Moving parts: Anything that moves on your window should be avoided when it comes to caulking. The opening/closing mechanism, the ledge of the window frame, and anywhere that the window touches when it's closed are places to stay away from if you want your window to open and close properly.

Caulking serves some very important functions for a painter -- from sealing out moisture and drafts from a building, to concealing cracks and gaps in exterior siding or interior walls prior to painting.
Next to that, we must reiterate the very important message that when you put new caulk on top of old caulk, you could be sealing in mold and mildew that lie beneath the old caulk. This is another very important reason that The Grout Medic's recaulking service always involves complete removal of the old caulk.
Caulking is an important part of painting and home maintenance, but it can be a bit tricky to know when and how to apply it. In general, caulk should be applied before painting, and it should be allowed to dry for at least an hour before any paint or stain is applied.
