Hi, how do you paint over 100% silicon rubber sealant?
I had smeared it in the corners of my bathroom, getting some on already painted walls and trim, thinking I can just paint over it.
That's not the case - it's not paintable - the paint is just collecting into bids. It's hard to remove the white stiff - I can scrape it with the towel and it would come off a little, but not much.
I would like to paint over it to cover it up. Latext paint is not working for this stuff. Anyone had experience with this?
Thank you very much,

- Inga

100% silicone caulk or sealant will not take paint of any sort. It is quite difficult to remove 100% silicone caulk completely.

The silicone can be primed with an alkyd primer, and that will allow it to be painted with latex. The silicone will 'bleed' oil for a long time tho so you should cut away any excess before priming and painting.

I should also add that you would want to wipe it down first with mineral spirits or paint thinner to rid it of surface oils. do this before priming.
