This article was inspired by a question from Adam who likes the smell of lacquer but wonders if you should wear a respirator while spraying lacquer:
“I’m using lacquer to finish a project. I’ve heard a lot about needing a respirator since the fumes are strong and offensive. I bought some from Lowe’s (Deft), and it has an almost sweet smell to it. I opened the can and was amazed at how good it smelled—ha ha! Could there be something wrong with my lacquer? This is my first time using lacquer instead of poly, so I really don’t know. I’m just wondering if something’s wrong since it doesn’t have the strong odor I expected. I’m also wondering if you should wear a respirator when spraying lacquer?”
Here’s a crucial lesson for all woodworkers: just because something doesn’t smell bad doesn’t mean it isn’t bad for you.
I totally get where Adam is coming from—I also think Deft lacquer smells pretty good. But hey, I also like the smell of gasoline, so maybe my nose is just broken. That said, not all lacquers smell pleasant. Some brands produce downright nasty, eye-watering fumes.
But let’s be crystal clear here: lacquer fumes are dangerous, no matter how they smell.
Lacquer contains volatile organic compounds (VOCs), which evaporate quickly and release harmful chemicals into the air. These fumes can:
Want proof? Check the Material Safety Data Sheet (MSDS) for your favorite lacquer. It likely includes warnings like:
“Vapor irritates eyes, nose, and throat. Repeated exposure to high vapor concentrations may cause respiratory issues, as well as permanent brain and nervous system damage. Intentional misuse by inhaling fumes can be harmful or fatal.”
Still think it’s no big deal? If you can smell lacquer, it’s already too late—you’re inhaling those chemicals.
A regular dust mask won’t protect you from lacquer fumes. You need a respirator with organic vapor cartridges—not just for safety, but for your long-term health.
I highly recommend the 3M 6500 Series Respirator. Here’s why:
✅ Comfortable fit—won’t make your face feel like it’s trapped in a vise
✅ Organic vapor cartridges—filters out harmful lacquer fumes
✅ Downward exhaust vent—reduces fogging if you wear glasses or goggles
If you don’t already have one, get one ASAP. Your lungs will thank you.
Lacquer is an awesome finish, but your health comes first. Stay safe, and keep breathing easy!
