Can you paint over 100% silicone caulk?

Non-paintable caulk is made of clear silicone. If you apply paint directly over untreated silicone caulk, peeling will inevitably occur. Fortunately, you can paint non-paintable silicone caulk as long as you treat it with a special base primer.

How do you keep caulk from cracking when painting?

This way when painting the woodwork with gloss/satin etc ensure you cover the caulk creating a barrier preventing the emulsion from cracking.

Can you caulk over 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.)

Can you put a second layer of silicone caulk?

Do not apply caulking in excess. Caulking can and will shrink as it dries. Sometimes a second layer of caulk is required and will produce a neater surface instead of overfilling a crack with caulk. To clean the area around the caulk, use mineral spirits for silicone caulk, and soap and water for acrylic.
