Painting over silicone caulk issue

I didn't see anything that would help during a hurried search so here I go:

My family and I recently painted our family room and to our dismay we found that whoever caulked our trim had several big splotches that went onto the wall and would not take the paint we were using. Obviously it is a silicone caulk, but we didn't notice how bad it was until we removed the painters tape after the 2nd coat Now the painted area around our trim looks like garbage.

Any advice would be great. Even if the advice is I'm out of luck.

A hearty thank you in advance!!

Well you now know something many people don't. Never use silicone on a surface that will need to be painted.

One solution is to paint the silicone with a shellac based primer, like Zisnner B-I-N. Once it's dry you should be able to paint over the silicone. If not, give it more primer and try again.

Yep, the only 2 choices are to remove the silicone or coat it with a pigmented shellac like Zinnser's BIN.

btw - welcome to the forums!
