Topic tags/keywords: thinner

I need to thin some shellac and here in Canada we cannot buy Denatured Alcohol (or at least I cannot find any) I can get Shellac thinner from Lee Valley at $14.50 per litre but I was hoping for something a little less expensive. Can anyone guide me to what else will work. Some of the items that I can buy here are: Methyl Hydride, Mineral Spirits, Toluene and Xylene.

Thanks
Earl

Have ya tried rubbing alcohol? Dunno about that, but it is worth a small trial sample.
Why no DNA in Canada? I do know that the stuff has gotten really expensive here in the states.

If you can’t find denatured alcohol, some junk vodka or rum (everclear is one brand) will do the trick.

Bacardi 151 might work too.
Isn’t DNA just moonshine with an additive that makes it (more) unfit for human consumption? I wonder if ethanol 85 would work?

Rubbing alcohol will also work. What makes alcohol “denatured” is additives that are added to make it taste real bad so that folks won’t drink it.

I’ve read there was something on the Canadian laws that makes DNA very hard to buy; related the math manufacturing or such. That “thinner” from LV may be your best hope, although I’ve heard of guys using flaming rum and other drinkable alcohol products, that may cost more than what LV wants (and that price is really painful). I was grimacing the other day here in the states when I saw DNA at $15 gal, $14.50 a liter would really get my shorts in a twist!

Doing some more research I have found a product called Bio Flame ethanol for fireplaces. They say it is 95% ethanol and sells for $25 for a gallon. I think I will have to give this a go as it is the best deal I seem to be able to find up here.

The best shellac thinner has as little water in it as possible. Remember this when considering distilled spirits or rubbing alcohols. Most of them have water in varying quantities. I occasionally use lab grade 100% isoprophyl (rubbing) when spraying shellac in some conditions, as it dries more slowly than other alcohols.

Kerosene, or other petroleum products, will not work as shellac thinner, but they make great lubricants for sanding or rubbing out dry shellac.

Also keep in mind that brushes dedicated to shellac do not need to be cleaned with solvent. When you’re done brush them on scrap ‘till they dry and put them away. Next time, dunk them in fresh shellac for a few minutes, and they’re good to go.

Personally, if I didn’t use an anhydrous product sold to dissolve shellac, I’d not risk my work screwing around with any booze other than pure grain (Everclear) 180 proof alcohol.

If it’s that much of a pain to get the correct stuff, choose another finish.

Thanks for the tip Cessna. I’m finishing a project right now and wrapping/my brush in plastic to keep it wet between coats. I’ll give this a try.

Due to the very weak corn crop this year we can look forward to alcohol pricing going up even more.

Rubbing alcohol can work but it must be the high concentration type. The one that’s 91% alcohol at least.

I don’t know of another solvent that will work with shellac. Pretty sure nothing petroleum based will work.
Acetone possibly.

We can import from other countries who can grow big numbers of corn crops per year. In this way we can help third world countries.

I pulled up the MSDS on the Bio Flame ethanol and it shows as 95% ethanol and 5% Propanol so I think I will give that a go unless some knows something about Propanol I do not.

Here are some choices that are pretty similar, chemically. You will see a few repeats of the suggestions made above.
