Painting Over and Under Silicone Caulking

By: Danny Lipford

Caulking around bathtub with silicone caulk.

“I am recaulking the area where a shower insert meets a wall that is painted with semi-gloss latex paint. Will silicone caulk stick to the paint? If not, can I use a different type of caulk around a shower insert?” -Kathy

Hi Kathy,
While 100% silicone caulk will stick fine to paint, paint won’t stick to 100% silicone caulk. If you plan to paint over the caulking, use a paintable caulk that contains silicone and resists mildew. If not, 100% silicone caulk is fine to use.

Good luck with your project,

Danny

    Hi I replaced my showers a while back and now I have painted. The latex paint won’t stick to molding where there is caulk. Old molding light brown now all white except a few spots around shower stalls. Please help how do I cover these small spots?

    I always wondered, how can paintable caulk really be possible? The whole purpose of caulking is to expand and contract, so if it’s been painted, won’t the paint simply fall off? Paint is not made to expand and contract. Any advice would be greatly appreciated.

    I made this mistake on a kitchen ceiling. I could not get the silicone off without gouging into the drywall where the wall meets the ceiling I put a thin layer of plaster patch over the silicone and used oil based primer on that. it isn’t that pretty but I am hoping it sticks.

    Hi Bob,
    Paint won’t adhere well if at all to 100% silicone caulk. You roughing it up with sandpaper and wiping it down with mineral spirits then prime it with a shellac-based or oil-based primer before topcoating. But your best best is to try and remove as much of the silicone caulking as possible by cutting it out with a utility knife. Then wipe the surface down with mineral spirits, allow it to dry, then apply a paintable caulk. After the caulk has hardened, prime it and the trim on each side with a shellac-based or oil-based primer. Allow the primer to dry, then topcoat.

    Hello, I made a mistake and used 100% GE silicone II white on the bathroom wood window frame that I intend to paint. My question is, assuming this material is unpaintable, what is required to paint this caulking? I was thinking about re-caulking this area with paintable white silicone. Will this work or is their a better correction method?
    Thxs.

    Julie,
    Sounds like mold or mildew. If so, there are several products on the market that will kill it, or you can use one part bleach to four parts water with a little detergent added to reduce surface tension. Apply using a pump-up sprayer, allow to remain on for 10 to 20 minutes, then hose off.

    How do you clean outside caulking? The seal around windows that are ten years old have discoloured i.e. are black and sooty.
