Shellac in a spray gun

[Castaway]

Has anyone had any experience or does anyone think that a touch up spray gun will work with shellac and vice versa, taking for granted that the shellac is properly put through a strainer to weed out any undisolved shellac to prevent clogs.

HMMmm! atomised metho around a sparky compressor in a shed full of electrical equipment, yep that's a good idea! can I watch!................. at a distance of course!!!

NO you cant watch, was planning on keeping the compressor insinde and spraying outside as I usually do. So any real advice.

I asked the same question a long time ago here as I wanted to refinish seven silky oak chairs with shellac and thought spraying maybe the way to go (HVLP spray unit). Major draw back with what I wanted to do was overspray and of course as already pointed out atomized metho. In the end I applied by brush for the first couple of coats rubbed back and then used a rubber ? (cotton cloth with cotton wool inside) to apply the shellac. Am really happy with the result and have to say it was very therapeutic.
Maybe it's a case of what are you finishing??

OK.. ADMIN intervention here.
The OP (castaway) asked a "method" question.
We don't know his shed setup........so lets just look at the method.

I.E...can you spray shellac.

Have used the same method on previous projects as well to great success. I have a new project that I thought would be better suited to spraying it on. Having problems with the shellac drying too fast as I'm having to go around cut outs and curves. I might try to brush it on again. But I'm going to give the spray gun a go and see what the results are. What other advice did you get when you first ask this question.

From memory that was about it. The over spray was the point that put me off as the chairs are quite fine and as there were so many angles that I would have had to point the spray gun, over spray would have also affected other parts of the chairs! And i'm no spray painter.
I'll do a search for the thread.

Intresting question - I for one could see no reason that it could not be done, though one would need to get the viscosity and air presure right.
I think that you would need to use more metho than a normal mix as the most will evaporate from spraying before the shellac hits the surface.
I would be intrested to hear the results.if some one has tried it.

Watch this get "flamed"
Anybody heard of airbrushes????

[Sapling]

No wonder I didn't remember much about it, was three years ago.

Hey Warren hows it going. Any new radios lately. Had a look at that phillips again and still could not get a model number. Yeah this project is a small Airzone Cub and was having trouble with the shellac in places. Well I just bought a spray gun online tonight so I will experiment and let you know.

Just had a look... interesting. Now I would of thought that you needed to decrease the amount of metho to make the mix a bit thicker to prevent evoporation.

Hi Peter. I think that if you used a thicker shellac you will require a higher air pressure and the metho loss from spraying could leave a thick coat that may not dry so easy.

I would use low pressure around 25 psi perhaps even lower to keep the evaporation down.and add a little extra metho as you do not want the spray to be dusty, but I am only guessing and perhaps your idea is correct,

As soon as I read your post I guessed that it may be a timber radio cabinet with lots of little areas hard to get at,

Peter on your philips radio you would have had a sticker with all the radio details on the rear panel I would guess that it has fallen off years ago.

And yes I have purchased another radio a HMV chassis with a smashed Plastic case but I only want it for parts to restore some other HMV radios that I have, also purchased another valve tester - a ( Paton VCT ) I hope to restore this one to working order,
Cheers

Yeah the back is missing of it so no sticker. Was hoping there was another on the chassis but no luck. Check your PM sent you a link to some radio stuff.
