Afternoon all. I’m contemplating trying my hand at spraying on my clear coat(s) on my chair build. I just brushed on the first coat and it took forever. I’m using “Varathane Diamond Wood Finish water based”. That’s the stuff I always use and I’m pretty satisfied with the results. The thing is I know nothing about spraying. I have a descent 4 gal compressor/hose but that’s it. I’m working out of a single car garage, but it does have a 200 cfm ceiling fan. I’m thinkin’ this might be a recipe for disaster, over spray, dust what have you. Whatcha think?

Mark, a foldable spray booth is very easy to make. One back wall with a 24” box fan with a furnace filter over it, 2 side walls at an angle to the back wall and a partial ceiling. You can find plans in many spray finishing books. Your compressor probably won’t handle much, but for spraying a chair it might be okay. If you don’t get better advice here, call Jeff Jewitt and he will give you expert advice. Spraying takes some practice, but that can be done using water in the gun and cardboard as the project. If I can do it, so can you.

The compressor may be a tad light for the job. The gun setup will make all the difference. The needle and tip must be the correct combo for the viscosity, and the gun should preferably be a pressure feed, though gravity feed may work.

I padded on gloss oil-modified warerborne poly like shellac
on my recent chairs. It turned out well and is forgiving.
Spraying is fine, but give the padding a try. You may be
surprised. It dries real quick like shellac and you can
lightly sand between coats in less than an hour. Way
less messy than a wipe on oil based poly too – I was
going to do a Maloof style finish on the chairs but I
went to the paint store and found out that in my state
oil based is getting hard to find. It was a happy discovery
because as it turns out I like the application process
better and it does build a film reasonably fast.

I plan to use shellac as a base coat in the future to give
the finish a little amber.

Thanks for the response gents. Loren, I don’t think I can get oil base in B.C. anymore. Thanks for the thought Art, but I don’t have an extra 24” in the damned garage. :)

It can be very light weight and stored in the rafters.

I use a compressor smaller than yours and have sprayed 7 foot wall cabinets with good results using a HVLP type gun set around 35 psi. I spray everything outside and use quick drying finishes.

It’s always about 85 to 90 degrees here though.

Once you have success spraying, I doubt you will do anything else. Especially with the low cost of gravity feed guns these days.
