Shellac, the last "brittle" finish?

It's starting to be more apparent every year that we will slowly see our beloved solvent-based finishes disappear in favor of water-based finishes.

I understand the VOC concerns but I still like my Alkyd Varnish and my Acrylic Nitrocellulose Lacquer, but I can see a time in the future when I won't be able to buy my favorites. 

Shellac may be the final frontier for non-water based finishes. Dissolved in alcohol, shellac may be the last survivor of the "brittle" finishes. What do you think?? 

I'll be in Denver this weekend (19-21) defending my viewpoint and I can show you three excellent ways to apply shellac. Stop by and say hi. Denver Merchandise Mart, 451 East 58th Ave.

I have tried it on my stairs and on my basement floor. It does show some scratches after a while.. But, come on! A floor! This is a tough product.

And to try to stay on topic... On my baswement floor it's sticking well to a gnarly solvent based sealer coat. With a shellac layer in between.

GEide GEide writes: I’m no shellac expert, but just to stir things up a little bit, (hope you don’t mind Rollie, :) ) have you folks seen Vijay Velji’s shellac DVD? According to a reviewer, in his DVD, Velji says that shellac actually has good resistance to alcohol if the shellac flakes are fresh. In the video, he even spills some scotch on a finish. After leaving it sit, the scotch doesn’t leave any damage.

What do you folks think of this? Do you buy it? Anyone had similar experiences? Or experiences where a drink DID ruin a shellac finish?

I was shocked (and I'm still annoyed) that I can't buy solvent-based varnish here in CT. I used to make my own wiping varnish for table tops other high use areas on furniture. However, there has been one good consequence stemming from the void:I know use shellac for my furniture. And I couldn't be happier.

It's not horrible for the environment, and far from the most toxic finish out there. I have never successfully brushed or padded it on - I spray it with my hvlp gun (thinned a bit). My favorite super easy finish recipe:
-pore filler if desired
-color if desired
-2 coats shellac, sprayed on
-light sanding
-glaze if desired
-1 coat of shellac
-light sanding
-2-3 coats minwax wipe on poly (wiped on), sanding between coats
-Pumice and rotten stone buff if desired

The result is a thin but durable finish that looks like many coats of oil.

I can't say that I see the end of products like lacquer or conversion varnish however. Companies like ML Campbell would essentially have to go out of business (I kind of hope you are right, for environmental reasons). Most guys I know spray conversion varnish. I used to be one of them. I just can't stand lacquer thinner and the environmental effects of spraying poison into the air...Plus my shop stunk for a few days.

I have never liked water based finishes, for the standard reasons (plastic, purple appearance).

I will be 1500 miles from Denver this weekend, otherwise I'd stop by and learn about shellac.
