I had a new front door installed. I put KILZ on the pressure-treated wood over the weekend. Last night when I tried to paint (hunter green) the frame areas around the door, I was getting “cracking” in the caulked areas. This morning, I looked at the door and I also noticed that the caulk that was painted is getting “mushy and rubbery.”
I am thinking that the contractor used a silicon caulk. I do want to have the hunter green color on the frame areas. I read that I could put a white shellac over the caulk. Should I get rid of the paint that is cracking (if so, how)?
Any suggestions?

No primer on the planet will stick to 100% silicone caulk. The first company that invents a primer for silicone caulk will make a fortune!
I recommend physically removing as much as possible then re-caulking over the affected areas with a good paintable caulking.
If this isn't possible, wipe down the caulking with denatured alcohol and a clean rag then prime with an oil based primer. The primer will never fully adhere to the silicone caulk, but will stick well enough to last for a few months before peeling.
Sorry for the bad news.

This may work.
You could mix a similar color oil paint into the silicone caulk, thin it with naphtha if its too thick and it should work.

Paint over silicon caulk.
Yes you can…If you caulk over top with a siliconized latex caulk. It will stick like a primer. I have 33years experience and have done this many times (407)909-1160 Orlando

Painting un-paintable silicone .
Re-caulk over the silicone with a paintable caulk which contains silicone then paint. it might work then again it might not. I use the water based Zinsser's latex two coats for this situation then a heavy coat of good paint. Rodda makes a silicone paint which might stick.
If you do remove the caulk be sure to use motsenbackers (@ home depot) silicone caulk remover to remove the silicone residue or the new primer won't stick either. 100% silicone caulk should be outlawed!!!!!!!!!!!!!!!!!!!!!!!!!
