Paint over non paintable silicon calk?

I have just finished installing crown molding in 3 rooms, I am ready to paint. Being I am in Florida with a possible humidity problem I use the GE paintable silicon calk. Somehow I made a mistake and bought the wrong silicon calk that is non paintable. Paint and primer will not stick. Any suggestions or am I screwed? If I have to scrape and peel it off should I wait for it to fully cure (24 hours).

You will need to wait until it fully cures to paint. It's not like the Silicone II that can be painted in 30 minutes. You will probably want to paint the silicone with a shellac based primer like Zinsser B-I-N, which should cover the surface... if it doesn't, apply a 2nd coat. Then paint.

Definitely prime the caulk with a pigmented shellac like Zinnser's BIN!
