For flips, I usually stick to low-VOC topcoats and just ventilate like crazy during primer. It’s a tradeoff, but at least I know the paint will actually last.
I get what you mean about the tradeoff. I tried a “plant-based” primer on a 1920s ceiling and it just peeled after six months—looked great at first, but didn’t hold up. Have you noticed any difference in adhesion between brands, or is it mostly about surface prep? Sometimes I wonder if the eco stuff just isn’t made for old plaster at all...

I’ve had similar issues with “green” primers on older surfaces. From what I’ve seen, surface prep is still king—if there’s any dust or residual moisture, even the best primer won’t stick. That said, some eco brands seem a bit more forgiving than others, but I haven’t found one that matches traditional oil-based for adhesion on old plaster. Maybe it’s just the chemistry of those old walls?
Yeah, I hear you. I’ve tried a few of those eco primers on old lath and plaster, and honestly, it’s hit or miss. Sometimes feels like the old walls just laugh at anything that isn’t oil-based. Prep helps, but man, those “green” labels don’t always mean better stick.
- Totally get what you mean about old plaster just shrugging off the “eco” stuff.
- I’ve been tempted by those green labels too, but honestly, sometimes it feels like you’re paying extra for a fancy sticker.
- My trick: I’ll do a test patch in a closet or behind furniture first. If it peels or looks weird, I just go back to the tried-and-true (usually oil-based, yeah).
- Prepping does help, but I swear, some of these eco primers just don’t have the grip for ancient walls.
- That said, I’ve had decent luck with a couple of water-based ones if I sand and patch every little crack first... which is a pain, but cheaper than redoing a whole room.
- Wish there was a straightforward “works on old houses” label instead of all the green jargon.
- Sometimes I wonder if the eco stuff is more about marketing than actual performance, at least for tricky surfaces.
Anyway, I’m all for saving money and the planet, but not if it means repainting every year.
- Been there with the “eco” paints—some just don’t cut it on old plaster, no matter how much prep you do.
- I’ve noticed some brands slap on all sorts of green badges, but when you actually read the back label, it’s mostly just marketing fluff.
- Had one “low-VOC” primer that looked fine for a week, then started flaking. Ended up scraping and repainting the whole wall with my usual (not-so-green) stuff.
- The test patch trick is key, but yeah, wish manufacturers were more upfront about what works on problem surfaces.
- Prepping’s a pain, but I’ve found if I skip even a tiny crack, the eco paint finds it and peels right off.
- Curious—has anyone actually found an eco primer that sticks to old horsehair plaster without hours of sanding? Or is it just a lost cause for these kinds of walls?
- Sometimes I wonder if we’re just not the target market for these products... maybe they’re better for new builds?
