Treat shellac just as you would lacquer or poly… as a solvent based coating. All the same precautions apply.

You’ll need to pre-heat the garage, then vent as you spray. Once the fumes have dissipated, close the doors and heat the garage again as the finish cures. Be mindful of any ignition sources such as a furnace or pilot light.

Not know your full setup it’s nearly impossible to say for sure if it’s a good idea. I do know one thing for sure Denatured Alcohol is very bad to breathe or get on your skin in long large amounts.
I work a lot with shellac and I’m lucky I haven’t experienced any drain bamage. :)

Shellac can be successfully applied in some pretty cool temps, I’ve used it down to 40º with no problems. That does slow down the evaporation of the alcohol slightly, but otherwise it works fine. You will want to prepare for the personal exposure issues, but otherwise you should be good to go. As always, if this is your first try, do an experiment to make sure you have all the bases covered.

I always wear a respirator so I am not worried about breathing it in, although I am probably due for new filters. I didn’t think about the skin exposure though, so thank you. I’ll make sure to wear long sleeves and glasses or goggles. It is also really good to know that shellac is fine at colder temps. I will probably just heat the garage up pretty high and then not turn it back on after. If I get it up to 80 it will take a couple hours for it to drop back down below 50

Indeed still solvent base, so you have the aerosols in the air, posing a danger with your heater.
Certainly the Ethanol is less exciting than lacquer thinner.

For the poison side… if you are worried about that, go buy a bottle of everclear from the liquor store… it is the same ethanol, but without the nasty “Denatured” aspect. (NOT the Everclear 151…that stuff is only 75% alcohol you want the 190 proof 95% stuff)

I’m not too worried about it. Hell, with where I live some other environmental thing will give me cancer and kill me long before using a little shellac. It does make me wonder though which is cheaper, the everclear or the DNA.

Breathing everclear is not a good idea. It is odorless and will make you drunk before you know it.

Should be wearing an organic vapor respirator when spraying… but it is no more intoxicating than spraying shellac dissolved in Denatured Alcohol… both are Ethanol, DNA just has few % poison added to it.

The big box stores are carrying “green” alcohol. Comes in a quart can with green on blue labelling. Look up the MSD sheets. Green is 95% ethanol, regular runs as low as 50-60%. ts a little more expensive but I don’t want to be sucking 40% wood alcohol.

Are you aware that everclear is grain alcohol, not wood or denatured. It is sold in liquor stores and people use it to make their own liquors. It is 190 proof (95% alcohol) and it will make you drunk. Way back when I was a young man, we used to add it to a coke and get blitzed very quickly. It is odorless, so no one could accuse us of drinking on the job. It is also very flammable.

Mr ROn – - DNA is Grain Alcohol (Ethanol), with some methanol added to make it poisonous.

Methanol also will make one drunk, but also blind.
As such – breathing DNA will make you as drunk as Everclear, but with other negative effects.
SO why not spray the “Non-Poisoned” version of ethanol- wearing PPE as you would using any organic solvent?

Perhaps look at this first

So two birds one stone?

That was a joke, just to be clear.
