I’ve seen folks skip the primer and go straight to paint, but honestly, I’ve had way better luck sealing it up first—especially with old wood. There was this one job a couple summers back, 1920s bungalow, sills were pretty chewed up. Even after scraping out all the rot and letting everything dry (took a couple days with a fan on it), I hit it with an oil-based primer before any filler or paint. It just seemed to lock everything down and gave the paint something to grip.
One time I tried skipping that step (was in a hurry, not proud of it), and sure enough, a year later the paint was bubbling and I was back out there patching again. Learned my lesson. Primer’s not magic, but it really does buy you more time before moisture sneaks back in.
I’m curious if anyone’s had luck with those epoxy consolidants? I’ve used them on sills that were borderline too far gone, but sometimes they feel like overkill for minor repairs.

I get the logic behind priming, but honestly, I’ve skipped it a couple times on newer wood and didn’t notice much difference. Maybe it’s just me, but for small repairs or spots that aren’t getting hammered by weather, I’ll just sand, fill, and paint. Haven’t seen bubbling—yet, anyway. Maybe I’m just lucky or my climate’s forgiving.
About those epoxy consolidants: I tried them once on a window sill that was half mush. Felt kind of like using a sledgehammer for a thumbtack job. For minor stuff, I’d rather just use wood hardener or even a good exterior filler. Epoxy’s messy and not cheap.
I hear you on primer—sometimes I skip it too, especially if it’s newer wood or tucked away from the elements. Honestly, never had a peeling issue on those spots either, though I wonder if it’ll catch up to me down the road. As for epoxy, yeah, total overkill for little fixes. I tried it on a door jamb that was just starting to soften and ended up with more mess than progress. Wood hardener’s been my go-to for minor rot—cheaper and way less hassle in my experience.

That’s interesting—I've only just started learning about wood hardeners, and I didn’t realize they’re that much easier than epoxy. I always assumed more “heavy-duty” solutions were better, but after fighting with a tube of epoxy that cured before I finished mixing it… yeah, maybe not.
Just curious, does skipping primer really hold up long-term? I always get paranoid about paint peeling, even if the spot’s hidden. My dad swears by primer for everything, but maybe he’s just old-school.
Yeah, I’ve had the same struggle with epoxy—either it sets up too fast or not at all, and half the time I end up with a sticky mess. Wood hardener’s definitely less stressful for small fixes. About primer, though… I still use it out of habit, especially on spots that get a lot of sun or moisture. Maybe your dad’s onto something—old-school doesn’t always mean wrong. But for hidden spots, I’ve skipped primer before and honestly haven’t seen peeling yet. Guess it depends on how paranoid you want to be about touch-ups down the road.
I hear you on the primer thing. I used to think skipping it was just asking for trouble, but the last time I did some trim repairs on the shady side of my house, I got lazy and didn’t bother. Two years later, still looks fine—no peeling or bubbling. But then, the window sills that get hammered by afternoon sun? If I don’t prime those, paint starts flaking in a year or less. Makes me wonder if half the “rules” are just habits passed down from when paints were worse. Still, I guess I’d rather overdo it than have to scrape and repaint sooner than I have to…
- Totally agree about the shady side vs. sun—UV just eats paint for breakfast.
- Modern paints are way better, but primer still saves headaches on exposed spots.
- I’ve skipped primer on north-facing trim and it’s held up, but anything facing west? Not worth the risk.
- Honestly, sometimes I think half my painting routine is just superstition... but scraping old paint is the worst, so I stick with what works.
Funny how painting routines get so personal over time. I’ve been through the whole “primer or not” debate with myself more times than I care to admit. On the job, I’ve seen a lot of trim that looked fine for a year or two with just a good paint—especially on the north and east sides, like you said. But man, those west-facing sills? It’s like they’re in a death match with the sun. I tried skipping primer on my own place once, thinking new paint tech would save me some time. Nope... two years later I was out there scraping and cursing myself.
Honestly, it’s one of those things where the extra step up front saves a ton of headaches later. And with Andersen windows especially, I’ve noticed their factory finish holds up pretty well, but once you start dealing with field repairs or touch-ups, it’s a different ballgame. Sometimes you get lucky and the paint bonds right to the wood or composite, other times it peels like an orange after one bad winter.
I had a client who insisted on using leftover paint from another project (not even exterior grade), no primer, right on exposed trim. Looked okay for about six months... then the first real rainstorm hit and it started bubbling. Ended up having to sand it all back down and do it right. Lesson learned, and now I just tell folks it’s not worth trying to outsmart UV rays or moisture.
I get what you mean about superstition too—sometimes I catch myself still doing things “because that’s how my old boss did it,” even if the products have changed since then. But every time I skip a step, it comes back to bite me eventually. Scraping flaky paint is my least favorite job—right up there with crawling around under decks looking for rot.
Anyway, I’d rather spend an extra hour priming than deal with callbacks or warranty work down the line. The sun’s got no mercy on west-facing anything...
I hear you on the “primer or not” debate. I’ve definitely had my share of regrets skipping primer, especially on those sun-blasted west sills—no argument there. But I do wonder if we sometimes overcorrect after a bad experience. Not every situation needs the full belt-and-suspenders approach, at least in my neck of the woods.
“But man, those west-facing sills? It’s like they’re in a death match with the sun.”
That’s spot on for the west side, but I’ve actually had decent luck skipping primer on protected trim (like under deep eaves or covered porches), especially when using some of these newer hybrid paints. Maybe it’s our climate—pretty mild winters here, and not much direct rain except in storms. I wouldn’t dream of doing that on exposed fascia or sills, but for spots that barely see weather, sometimes it feels like overkill to go through the whole prime-sand-paint routine. Haven’t had any callbacks yet (knock on wood), but maybe it’s just luck.
The Andersen factory finish is a weird one too. Sometimes it holds up for years, other times I swear you look at it wrong and it starts peeling. I’ve always wondered if that has more to do with how well folks prep before painting over it than anything else. I know people who swear by scuff sanding and deglosser before any touch-ups, while others just slap paint right on and hope for the best.
I totally get sticking with what works—nobody wants to be scraping paint off in August—but sometimes I think we carry old habits forward even when products change. Anyone else feel like manufacturers hype up “self-priming” paints more than they deliver? Or is that just me being skeptical after too many years fixing other people’s shortcuts?
Anyway, I guess I’m saying there are spots where skipping primer hasn’t burned me (yet), but maybe that’s just playing with fire...
Right there with you on the “self-priming” paint hype—most of it’s just marketing, in my opinion. On protected trim, I’ve skipped primer a bunch and haven’t seen peeling yet, but I’m always holding my breath. The real kicker is surface prep. If you don’t scuff that Andersen finish, it’s basically like painting glass. I’ve seen paint just sheet off after a season. Seems like the new products are better, but nothing replaces decent prep work... even if it feels old-school sometimes.
