Typically you take the cabinets off the walls to paint them. I know that's much more work, but it allows you to get into all the sides and nooks and crannies (this is why I've never painted kitchen cabinets!!!) If you keep them on, it doesn't matter. Either way, you'll have to touch up wall or cabinets. Remember to use blue painter's tape to mask off the walls, so you don't pull paint off. Zinsser is fine, so is Kilz.

If there is a coat of paint on there then with a light sanding you can use the old paint as your primer and just paint on top. Make sure that your get any gloss look out of it before you paint. Most SW paints will not stick to any glossy surface.

Talked Mom into 1 coat this morning. We'll see how it looks tomorrow but I have to do walls so 2nd coat on ceiling may have to wait til Jan. But now she's asked me to do the other bathroom's ceiling! She was just worried that sheetrock would pull away from ceiling (or texture would pull off rock) b/c original 1970's ceiling was textured, not sure if painted, but then more texture sprayed on (when all I wanted was contractor to do taped joints where he reframed for shower stall), then 2 coats of Kilz she thought 2 coats of paint would break the camel's back!

That is unfortunate to hear that the painter/wood installer you hired, did not sand or prime your cabinets before painting. We always recommend that you check the license/insurance of who you hire before hiring them to avoid this issue. He is most likely not licensed. A simple license check with your state will prevent many of these issues from ever occurring in the first place. Because he did not degloss, sand and prime the cabinets (and then wait the appropriate amount of time for the primer to cure) before painting them, then you will unfortunately need to strip the cabinets and start over. Our company specializes in painting cabinets as well as stripping cabinets- We have fixed a LOT of jobs around our area, where homeowners "went cheap" and hired an unlicensed/unqualified painter and paid the price. This is very, very common. We probably do 2 jobs a week to fix the mess of someone cheaper. I really don't understand why more people do not just hire professionals the first time, why tempt fate... but I digress. There is no quick fix here- you will need to do things the right way from here on out, unless you want to experience this problem all over again. So again, you'll need to have the cabinets completely stripped then cleaned, prior to sanding, oil priming and repainting. Or you could just buy new doors entirely, and negate needing to do the stripping and cleaning work for the cabinet doors. (You'll still need to sand, oil prime and paint them.) I recommend hiring a professional to finish this job, as most likely this guy is just going to do things wrong again. They always do. If he isn't smart or diligent enough to even do a basic google search or crack open a textbook to understand cabinets need to be primed, then do you really think that he's going to magically become a cabinet aficionado the second time around? Most likely not. And if he does a bad job stripping the cabinets, he may cause further damage, like deep scratches, uneven stripping, etc, along with wasting more of your money on materials and time.
