    Spraying varnish

    Hello all,
    Anyone ever use a regular automotive type spray gun to sray varnish?
    I'm just finishing up a sliegh bed i've been making for my nephew and would like to try something differant. I usually do the wipe on Poly thing which for what I do works OK, but is very hard on larger projects. Im putting a coat of BLO on first, let it dry, then spray a couple of coats of Varnish. Does this sound doable with a Sharp's auto type spray gun?

    Thanks,

    Jim,

    I am "Finish Challenged" so I'll just wait to see everyone else's answers. But I love the bed!! Very cool.

    I've never tried it but everything I have read on the subject says NO. I would recommend spraying a coat of shellac (blond dewaxed) over the BLO then several coats of laquer.

    Most folks do not recommend spraying varnish. Not because you'll get a bad finish because with a properly adjusted gun and good technique you can get a very nice finish. The problem is that varnish dries very slowly in the scope of things and you'll end up with a sticky mess ALL OVER from any and all overspray. The best finishes to spray are those that dry/cure quickly...NC lacquer (with proper environmentals and personal protection and not anywhere IN your house), water-bourne acrylic products, shellac, etc.

    If you want to use varnish on your project, stick with wiping or brushing. IMHO.

    While I am not certain, I think that the only varnish that is commonly sprayed is conversion varnish. This is a two part varnish that dries quickly and is among the most durable of finishes. I believe that it is typically the finish on a factory produced kitchen cabinet, including as a clear coat over paint. I do not spray it, but have had it done at a finishing shop for a job or two that seemed to require this durability. I think it has to be mixed quite carefully, and that clean up is a PITA.

    Thanks for the replies.

    I'll try lacquer then, instead of varnish. Thanks again for the help, almost pulled a boo-boo
