I am trying to spray latex paint with a Binks mach1 HVLP gun and a pressure pot, with air pressure at 50lb at the gun and the pot reading at the end of its gauge at 16lbs. I thinned the paint 10% with water but am still getting orange peel. I don't know how much you can thin latex. Anyone else able to spray latex successfully? And yes, I normally spray ML Campbell resistant with great results. For this project, the owner wants latex.
From contributor D:
A lot depends on the specific brand you are using. You can probably push the thinning of it a little more but not much. There are flow-out additives you can try, and play with your pressure and needle air cap size if you have any others. I have often found that with latex, a cheap hardware store gun works better than the same Mach 1 you have or even a 2001 which usually will lay out anything beautifully. If you still have an option of switching product, Muralo brand lays out as smooth as silk.
In an earlier experiment, I tried various dilutions of Floetrol and water with the Behr, and the results were quite disappointing when compared with the Thin-X Latex. Then I tried thinning some Break-Through white satin with the Thin-X Latex, and oh my goodness, does it ever work well there. Thinned 10% with the Thin-X Latex, the Break-Through sprays beautifully. I'm going to guess that other 100% acrylic paints would behave just as well, such as waterbased Ben Moore Satin Impervo.
I'm only an amateur, so exactly how the cured finish will behave over time is still the big question for me. I would be curious to know if any other real professionals have had experience with this product.
Finally, my local Ace Hardware store here near Sacramento was able to special order a case of quarts (six of them in a case). I understand that Sherwin Williams and True Value Hardware can do the same thing.
This is one of the best new products that I have tried. We thin all our latex interior as well as exterior paints with this product. When spraying interiors, this product actually gives the paint a sheen that can not be had without Thin-x. One other new product we are using is Crawford's lightweight spackle. This is great stuff for small cracks on doors, windows, and walls.
