“sometimes it gets tacky if the weather’s off”
I totally get that—shellac can be unpredictable, especially when humidity messes with drying. I’ve had similar issues and honestly, patience isn’t always my strong suit either. I’ve found that giving it a little extra time sometimes helps, but not always. Maybe it’s just one of those finishes where you have to roll with what you get... Still, your pieces sound awesome even if they’re a bit soft at first. Don’t stress too much about it.
Title: Building Green? Watch Out For Those Sneaky VOCs
Yeah, humidity really throws a wrench in the works with shellac. I’ve noticed even just a muggy day can make it feel gummy for hours. Sometimes I’ll use a fan to help, but it’s hit or miss. Still, I love how natural it is compared to some of those high-VOC finishes.
Title: Building Green? Watch Out For Those Sneaky VOCs
Shellac definitely has a mind of its own when the air gets damp. I tried finishing a couple of window sills last summer—figured I was being all eco and clever—and ended up with this weird tacky surface for almost two days. My dog’s fur stuck to it, which was a look, but not the one I was going for.
I get what you mean about the natural appeal, though. There’s something reassuring about knowing exactly what’s in your finish (especially after reading too many horror stories about off-gassing from “eco-friendly” brands that still sneak in the chemicals). High-VOC stuff freaks me out, honestly. We moved in not long ago and I swear the smell from some of that builder-grade paint lingered for weeks.
Still, I do wish shellac was just a little more forgiving. The fan trick helps sometimes, but I’ve also had it blow dust right onto my wet finish... which is its own kind of fun. At this point, I’m starting to think there’s no perfect answer—just trade-offs depending on weather and patience levels.
Anyone else try those low-VOC polyurethanes? Curious if they’re actually as low-odor as advertised or just marketing spin. My partner’s sensitive to smells, so we’re constantly sniff-testing samples like weirdos at the hardware store.
Anyway, glad I’m not alone in battling humidity and sticky surfaces. If nothing else, it gives me a good excuse to procrastinate on those last few trim pieces...
At this point, I’m starting to think there’s no perfect answer—just trade-offs depending on weather and patience levels.
Yeah, that about sums it up. I’ve been down the same road with shellac—tried to refinish some old baseboards in the spring and ended up with a sticky mess for days. Humidity is the real wildcard. Even with windows open and a dehumidifier running, it just wouldn’t cure right. And then, like you said, every bit of dust or pet hair in the house seems magnetized straight to your project.
Here’s my take after a few years of experimenting:
- Low-VOC polyurethanes do seem to be less smelly than the classic stuff, but "low-odor" is a stretch. The water-based ones are definitely better for indoor work (I used Bona on our floors), but you’ll still notice a chemical whiff for at least a day or two.
- Some “eco” brands are all marketing—read the fine print. I picked up one that claimed zero VOCs, but the MSDS listed all kinds of unpronounceable stuff. Ended up returning it.
- Oil-based anything is out for us now. The off-gassing lingers forever and gave my wife headaches for days. Not worth it.
- Shellac’s great when it works, but yeah, it’s finicky as hell. I’ve had better luck with smaller projects or when I can control the temp/humidity (basement in winter, basically). For trim or big surfaces, it’s just too unpredictable unless you’re super patient.
Funny you mention sniff-testing at the store—we do the same thing. You’d think they’d have sample boards or something instead of making everyone pop lids and take their chances.
At this point, I mostly stick with water-based polys for anything big and save shellac for touch-ups or stuff that’s easy to redo if it goes sideways. Still haven’t found a finish that checks every box: safe, durable, easy to use, and actually looks good.
If you ever figure out how to avoid dog hair in wet finishes, let me know...
Honestly, I think water-based polys get a bad rap for durability. I’ve used them on high-traffic stairs and they’ve held up surprisingly well—no yellowing, either. But I actually like hardwax oils for certain projects. They’re not totally VOC-free, but the application is forgiving and touch-ups are a breeze. Plus, the finish feels more natural than poly or shellac. Might not be for everyone, but it’s worth considering if you want something less plasticky. And yeah, pet hair is just part of the process at this point...
