I have an HVLP gun that I use for spraying latex backgrounds. I have to make it so thin to spray it stinks.
Is there any type of gun that will spray the latex right out of the can and still produce a smooth finish?
Also, I hear a lot of people talking about acrylic enamels. Who sells it? Do you get it at the automotive paint supply or chain stores like Benjamin Moore, Sherwin-Williams, Porter, etc.?
Thanks.

Amy, About the only gun that will lay it down nice that way is an airless. It is great for large jobs (over 100 sq. feet), but you normally end up with 1 qt. in the hose when you finish. Some or most of that can be reclaimed with practice, but they are not recommended for small jobs. I have yet to see a cannister airless work well. The thinning should propose too much of a problem. I spray it through a 1.4 tip although a 1.8 would be better. The primer tips I think are just too big to flow well, but I haven't tried them.
Oh, and on the acrylic enamels.... Yes, automotive paint stores, but be prepared with the checkbook to get started. About 200.00 for the basics (thinners, sandpapers, hardners, strainers, etc.) You will really like the results, but will need to do more prep work up front. The finishes will telegraph any and all problems from below. I would not use them on wood, just HDU, and metal.....Jack

Karl Reeder did a airbrush demo on a 4x8 panel at Paint the Prairie Letterhead meet in Unity using a CapSpray HVLP all in one sprayer and compressor unit. He didn't seem to have any problems spraying it on for a smooth finish and he didn't dilute it either. He was spraying Diamond Vogel latex. They say the Capspray is the finest HVLP unit on the market. Karl came across this unit when it was suggested to him by his paint supplier Diamond Vogel paints. It may be a good idea to get a hold of them for any questions you have about your finishing problems. I'm not sure who his dealer is or where he is located.
Do a google search for Capspray CS9100, the unit he was using. Quite the deal at gleempaint.com

Yup. CapSpray. Ours does the finest to the heaviest paints with ultra smooth finishes.

Hey guys,,,Does this gun come with a variety of needle and tip sizes, or what. Spraying thin a thick stuff through the same nozzle is more than the gun, its magic. Ask a goose.....
Here is a link that has pricing and model info on the CapSpray. I would like to see one operate before buying.... I have not seen the quality of atomization they speak of, come from a turbine gun in that price range, but would be happy to find one. http://www.cometobuy.com/elitefin/capspray.asp?number=20

I have the Wagner 220 airless sprayer. It sprays Benjamin Moore Moorgard very nicely with only a 5 or 10% reduction. It sprays a very even pattern at 1600 PSI at the nozzel. Easy to clean up afterwards, too. Available at Wal-Mart, Home Depot, etc.

Alfred - I loved the HVLP unit when we saw it in Unity - have you checked into Canadian availability. I'm sure the paint they were using isn't sold here.

automotive paint(acrylic enamel)is good for most any job. stop and think about what your car finish has to indure over 5-10 years. i perfer A/E over any latex for a number of reasons. A/E drys in an hour(fla sun baked)you can paint on it with one shot, make a mistake and wipe it off without messin up the background. vinyl adhers to it much better then vinyl will stick to latex. ive had problems with some vinyls not stickin to some latex paint. cost of a qt of A/E is $18-$30, you need to reduce(reducer is $20 a gal) it 50% so a qt of paint is really 2 qts. it covers better and is less tranparent. as it ages it doesnt chalk off like most other paints. bad things are you need to have spray booth(if you live in tight neigborhood)and you cant breath the over spray, need mask, and if you add hardner, it requires another type of mask and is more deadly. if you go to some auto paint store...they are just like home depot-lowes, they have mis-mixed paints. these can be bought for some place $5 a gallon. if they dont sell em then they got to pay to have hauled off.

Correct Deb, Diamond Vogel is not available in Canada, DV is a regional paint company, mostly in the Midwest, Minnesota to New Mexico region. The CapSpray is made by Spraytech a division of Wagner so that should be available in Canada.
Jack, here is a chart for different nozzle sizes for the type of paint you are spraying.

Wagner makes a product for their airless spray guns for reducing latex paint that I've had great success with. Its called Paint Easy. It doesn't really thin the paint all that much. It couldn't considering the small amount that you add. What it does is it breaks the surface tension of the paint so that it atomizes better.
I also add this to latex stain to be brushed onto sandblasted HDU backgrounds. It makes the latex stain relax and get into the cells of the HDU easier than straight stain.
I also looks and acts exactly like the stuff Auto Air sells to thin their airbrush paint.

Amy, I only spray Sherwin Williams DTM latex through mine so it may behave a little differently, but I thin it about 10 to 12% with water (a little less than 1 pint per gallon). Some latex paints may not spray that well but this stuff does.
I just did one friday with my HVLP gun and a 1.4mm nozzle and it's almost like glass, no runs. When loading the gun, I strain the paint through a piece of pantyhose to make sure it's clean. Adjust the fan (the thumb control on the side) to about medium. Keep the tip of the gun about 12" from the surface, use overlapping passes. Don't go too slow or too fast but just enough that the paint "burns in" or looks uniformly wet without looking grainy. Not too much so that it runs but just enough to level out and look wet. It might look thick to you but after the water evaporates, leaving only the pigment and binder, it will shrink to a thin film and be very smooth.
Spraying latex solid color stains on sandblasted backgrounds will amaze you when you try it. It's easier than saying spray latex. And saves a lot of time.
I use a 2.2mm tip for spraying primer only.

I also have a conversion gun, an Apollo, that does a decent job. It's a HVLP that can use either turbin or compressed air. It does require alot of compressed air though so isn't a good solution for large jobs with that configuration unless you have a large compressor/tank setup.
Also Floetrol helps the thicker latex paints spray and lay down smoother.

I forgot, floetrol does very well. Watch the humidity when you're spraying with floetrol added becuase it does retard the drying time some and it improves the flow of the paint. If you use too much, any vertical surfaces could run. The humidity was 78% when I sprayed the sign last friday which was a little high to suit me but fortunately it did fine. I would much rather spray when it's 50% or less.
