Should we use paintable caulking at the joints of the shower surrounding tiled walls and ceiling (drywall ceiling)?


It doesn't really matter if the ceiling joints are caulked with silicone or not. Silicone is used so that water does not enter. Most good latex caulks would handle this joint just as well because there isn't direct water pressure - I understand you have steam and splashes.

My advice would be to use a latex caulk that matches ceiling color (hopefully white!) and not paint it. Painting even paintable caulk will not last above a shower so why do it? I also actually prefer latex here as I feel I can apply latex thinner and smoother in a corner leaving less chance for peeling in the future. Silicone is just fine too just my preference - even when being careful you will smear silicone more and end up with larger lines more susceptible to damage later on. (I used latex above my shower in current home and 8 years later looks brand new)

  • I agree, but the caulk the OP is asking about is probably "latex with silicone". It behaves much like latex but with a little better bond and shrink resistance. – isherwood Oct 14 '19 at 20:10
  • Was the latex caulk you used a tub and tile caulk? Those are great because they do not yellow. However painters caulk will yellow over time if left unpainted. – Kris Oct 14 '19 at 20:59

Do you want to paint the caulk ? If you want to paint it then you need paintable.

If you do not want to paint it then Given the amount of moisture and condensation at the top of the shower i would use Mold resistant 100% silicone.
