I didn't take any pictures of the problem, so I will describe for you, as best I can, the nature of this beast.
Umm...Some tape peeled the paint off my trim.
I think that sums it up pretty well.
What's happened is, during the course of taping off our kitchen to work on drywall, floor, etc, the masking tape-- and even blue painters' tape-- has peeled bits of paint off of the doorway trim. I blame part of this on a certain someone's reckless ripping off of the tape. But mostly, I think this might mean that some PO painted latex over oil without proper prep. Or that the oil is so old that its doing its whole crumble and FAIL routine.
It's not terrible, and it's only on a few pieces, but I'm trying to decide how best to alleviate this crap. I want to paint this trim soon. I will be using a low-VOC alkyd. It seems to last much longer than latex; I know that latex has come a long way, but I was sitting in my mother's house the other day when I realized that we painted her trim almost 20 years ago. A good scrub with a magic eraser, and it'll be like new. That shit's like a candy shell.
Anyway, I cannot take the trim off of the walls for a variety of reasons, namely due to the fact that the house was drywalled around the trim. I fear I would be opening the most giganticest can of worms ever.
I also considered priming with a serious business primer and succumbing to latex, but we've already painted the yet to be installed base shoe with oil.
So, I'm not sure how to proceed here. The trim is a variety of shades of white throughout the house-- so I think some is oil and some is latex (and the bathroom's is, whatever the base, FLAT FINISH. grrrr. That irritates me so much. It looks sooooo dirty. It IS so dirty). Considering the age of the house, and the many colors that we have see on the trim, I know that whatever's under the possibly-latex layer is oil.
My questions are these: If I prime with something like Kilz2 and paint with oil, am I, somewhere down the line, going to see a problem wherein the maybe-latex layer and surrounding oil/primer lose adhesion? Or will the oil, with its hard candy shell, be ok once it's cured?
Also, how should I handle the pieces with peeling paint-- should I use a stripper (heh.) to get the top layer or two off? Since we're not taking these pieces off the wall, they'll have to be stripped in situ, so I'd probably want to use something like a citrus or soy based remover. I'd prefer to sand as little as possible, due to the lead content.
Should I just wet scrape and prime-- then paint? I'm using a semi-gloss finish, so I don't want too much bumpiness...Scrape, "fill," sand, prime, paint?
I guess I'm leaning toward first trying to scrape. If that's bad, then chemically (or citrus-ally or soy-ally) stripping the face of the trim, then doing some serious priming and painting; and then simply priming and painting the un-peeled trim.
