Topic tags/keywords: tip question spray gun finishing

I have found myself building projects is multiple quantities, and then comes the unfun part of painting and varnishing. I have always done this by hand with a brush. but yesterday as I was painting 12 display boxes I was dreaming of a sprayer… I have no experience with this tool. dose anyone have any helpful tips? should i go electric or neumatic. I only have a 5 gallon pancake compressor and I don’t know if that would supply enough air or not…. any info will be helpful…..

Depends on the sprayer. My compressor is 20 gallon and 6 HP and has trouble keeping up with a standard siphon gun. An HVLP gun may do the trick, but I have no experience with them.

HVLP is the way to go Micheal. Simple, compact, easy to clean and maintain. About as loud as your shop vac and about the same price range too!

I agree with Earlextech, I have a HVLP sprayer from the 80s. It works great and barely stresses a 5 gallon compressor. If you find yourself limited by the compressor, you could hook up a tank in parallel with it for a little more post-regulator flow capacity (http://www.harborfreight.com/5-gallon-portable-air-tank-65594.html). In my experience once you get the hang of the sprayer and get the settings all dialed in they work quite well.

The only tips I have are practice on scrap first, and don’t let the sprayer reservoir get below about 1/3 full or so (below the pickup). Once it gets too low it will start sucking in air and you’ll get spattering all over. Sometimes it helps to dilute whatever you’re spraying too, for latex paint I typically go about 50-70% paint, the rest plain tap water. It needs more coats but gives a very fine finish.

I love my Fuji Q3 HVLP. I’ve had compressor sprayers and HVLP is head and sholders above them.

I have an Earlex HV5000 … wouldn’t hesitate to recommend it to anyone. Bought mine on sale at Highland Woodworking.

Michael,

If you are going to be doing a lot of spraying moving forward, I would suggest an HVLP system comprised of a turbine (not compressor) and gun. I’ve got a dedicated HVLP turbine that filters and cleans the air, and keeps it at the exact right PSI, giving me an excellent finish every time. There are many makers of these kits, just do a Google search.

IMHO, the Wagner stuff you see at the box store is junk.

I borrowed a Wagner sprayer from a friend to paint a fence once. I can definitely say I’d NEVER buy one! Junk is right!

Michael – At the blue big box look at the 2900 and the 3900. Same machine but the 3900 has extras. About $140.

That’s 50-70% by volume paint and the rest water, sorry it’s unclear. Basically I just experiment until I get it right. Your results will vary with different paints, but I’ve found about half and half to be a good starting point, and then you can add water to thin it out a little if needed.

If you’re still looking, I have an Earlex HV5000 that I might be willing to part with. Great system, I just don’t use it enough to justify keeping it around (was an impulse buy). Let me know if you’re interested. They’re about $340 brand new.
