Paint coming off indoor window sills when things placed on top
Whenever I put something on our indoor window sills, then remove it, the paint on the sill will get messed up. It's been at least a few months since they were painted so the paint should have cured by now. We have several plants on the sills and I put little adhesive felt pads on the underside of the saucers thinking this would work. To the contrary, the felt sticks to the paint, leaves marks on it, and in one case, took the paint off with it!
I'm at a loss. Is it a problem with using the wrong paint/application or is this just something one has to accept with painted sills? FYI the sills were painted before we bought the place, but I'm pretty sure they used standard latex semigloss without any kind of sealer on top. The sills are made of wood, but I don't know what kind. I'm totally willing to repaint the sills the right way if that's what it takes. Otherwise, my guess is we'll have to put something on top of the sills to protect them. Any ideas?
