Dining table painting help
Hi All,
Trying to paint my dining table which was stained before to a oil based black semi-gloss Glidden paint. I have sanded down and applied an oil based primer (Kilz) and then applied the black paint using a Wagner 2200 PSI paint gun. Well that turned out to be a disaster as the finish was not smooth (not mirror like finish)..It had tiny dimple like look and not good.
So now I have sanded it down again and applied primer again. Now I got a Husky HVLP paint tip and an 35-140 PSI air compressor. I will be painting the semi-gloss oil-based Glidden black paint again.
What I need to know is how much air pressure (in PSI) should I set the air compressor to for the paint to come out smooth (like a mirror/powder smooth finish)? I appreciate the help.
The Husky Gravity-Feed Spray Gun that I have are spec'd as follows:
Model # 551-334 (Husky)
Fluid Nozzle: 0.055"
Paint Viscosity: Low-Med.
SCFM: 6.2 Avg @ 40 PSI
Fan Pattern: 1.5 - 10"
Link for the Spray Gun is:

Appreciate any responses. Thanks

What are the specs for the cmpressor.The specs for the gun are average. The compressor will have to put out at least the minimun requirement[probably more] constantly.
I would reccoment bringing back the gun and compressor and renting a good hvlp unit from a paint store. Unless of course you have some use for the spray setup.
Thin the paint and use the proper tip. With oil based paint you will have a dust problem. I would reccomend some of this stuff or a similar product. If you plan to use it ask about what you need to clean up with.

specs for air compressor
Hi Joneq,
Man I have checked so many paint stores here in Dallas but none of them rent a HVLP unit, I actually wanted to rent but since no option, that's why I bought it..Is the Husky HVLP that I have no good?
THe air compressor specs are:
This is what's written on the box:
Porter Cable, Model # CFBN125A
Uses 5/8" to 1-1/4" x 18 Ga. Brads (???)
2 HP Peak, 6-Gallon Compressor
Oil-Free Pump - No Oil Spillage
High Air Output (3.7 SCFM @ 40 PSI % 2.7 SCFM @ 90 PSI)
Range is 35 PSI - 135 PSI
So what should I set that to, in order to get a good quality finish?
Oh yeah and actually my wife just told me that she does NOT want a laquer or piano type finish..She says that the paint job should be smooth w/o any dimples or paint effects.
Appreciate ur help bro..

negative on that compressor
High Air Output (3.7 SCFM @ 40 PSI % 2.7 SCFM @ 90 PSI
you need 6.2 at 40 and that is probably for water like paint.
If you thin the paint down you could use this I think. Talk to the guy tomorrow. to make sure it will do what you want.

There is a cambell hausefeld in the depot too. You need to have the proper tip[small] to get the finish you want. These may not come with it.
Some one on the site will probably check in later with a solution. He is a spray expert.
Whatever you do don't go out and buy a $2000 unit.
I see that link don't work. Do a search for this.

wagner
Thanks a lot bro for your help..it was good I found this site :-)
But you are definitely saying NOT to use the compressor I bought and the Husky spray gun, but rather get that Wagner HVLP system?
I will check later as well to see if the paint expert posts anything. Thanks a lot again.

I would wait for the guy to post. I think He had a situation like yours and he did use a similar gun. It may be that with proper thinning it can be done. You could also use the apollo product and clear coat with a clear semigloss

Help needed ASAP
Ok couple of things, just need verification:
1. Would a Wagner Fine Spray 2400 HVLP work for what I am doing?
2. If not, then the Husky HVLP spray gun that I have, would the following compressor be sufficient:
Husky Model WL6510
5HP, 17 Gallon
6.5 SCFM @ 40 PSI
5.1 SCFM @ 90 PSI
150 PSI MAX
Please advise as I need to start painting today. Thanks

That compressor will work. I hope you are not buying it just for the table. I think that with the right tip the wagner will work. I do not know what you get with it so I can't guarantee anything, but the big compressor will work. I would pick up a regulator[pretty cheap] that attaches at the gun so that you can increase the pressure in the tank and regulate it at the gun, also something to keep the oil out of the air if it is not an oiless compressor. This will ensure that you will get enough CLEAN air for atomization without running out in the middle of the table. Run some tests BEFORE you go near the table.

paint thinning
Ok i just did a table leg with the Wagner HVLP 2400 and it's not much different than what I had before..Could it be the paint viscosity itself? Do I need to thin it out a lot (with paint thinner or naptha) before I paint? I used a viscosity instrument that came with the wagner and it said that the paint shuld empty that instrument in 40 sec, well it did not..it emptied in like 2 min..what do you think, can the pattern of paint (not smooth) that I am getting could be due to the viscosity? Thakns

thin it till it empties in 40 seconds. The paint is not atomizing correctly . It is too thick. Use something other than the table to test it on. thin with the naptha. I don't know what other adjustments you can do with the gun. I don't have one. Don't make the fan pattenn too wide and if there is an adjustment for paint flow[trigger] play with it. also keep the tip where the paint comes out even or below the cap[where the air comes out] if it is beyond the cap it reduces atomization. Like I said I don't have the gun and it probably doesn't have all these adjustments but just in case it does.
If all else fails read the directions if you haven't already. Look for troubleshooting tips.

Wagners really aren't meant to paint furniture with and achieve a nice finish. You need a cup gun.
As mentioned, the paint is too thick. It should run off continously. Not as thin as wood stain. You want to see a little thickness to it.
It's better to put more thin coats on than a few heavy coats.
You must make sure the tip is clean from debree or that will have an effect upon how it sprays. If you can, pull the needle out after each use and clean it.
Have you looked into buying lacquer based paint from Sherwin Williams? I do believe they sell it. That way you won't be having so many issues, but you will need a cup gun to spray it properly.
Attach the regulator right to the cup gun and then attach your hose to that. Keep the Psi around 40. Adjust as necessary, but don't go over 45.

Better
Ok so I used the Husky paint gun with the air compressor and diluted the paint with thinner and now the first coat of paint came out nice (a lot better than before) but still a little un-smooth..
So I know I have to apply a second coat (cause of uneveness of paint, patches, etc), but should I sand it down with 600 grit wet sandpaper before applying a second coat? And also sand it again after second coat? Thanks
