Dynastus 33 oz Siphon Feed Spray Gun - 2.5mm Nozzle for Spraying Oil-Based or Latex Paints, with Filtering and Cleaning Kits

Used this paint some concrete forms with latex paint. The paint itself was moderately thick, and I did add about a third of the container of water just in case. It took me a minute to fine tune the spray amount and pattern, but it worked pretty well for its intended use. I used a large sandblasting compressor for the air supply which seemed to properly mist the paint for application. Cleanup was simple, just sprayed water through the gun. Rinsing out the container was easy as well, and it didn't make much mess at all. Cleanup took less than 10 minutes. I only have extremely thin, extremely cheap latex paints so I doubt, in my case, that the watering down step is even necessary. The paint also has metallic flakes, but that didn't seem to cause any issues with clogging or spray pattern. Pretty decent result for my uses, and I'd buy it again for rudimentary projects that don't need to look top notch.

I have had very good luck spraying both latex exterior and interior enamel and also 100% acrylic paints (like Sherwyn Williams Pro Classic), but there are some caveats. These are VERY important. 1. The paint MUST be diluted. For each quart of paint, I use 8 ounces of Floetrol and 4-6 ounces of water. These must be mixed thoroughly and MUST be put through a paint strainer on the way to the cup. The flow rate is 35-40 seconds in a Ford #4 cup. Like thin pancake batter. 2. The compressor used for this gun must have some umph. I use a six HP Devilbiss (33-gallon tank) that can crank out over 10 CFM at 90 psi. If you are going to use a smaller compressor you will be disappointed. This gun takes a lot of air. It is not an HVLP gun but one of the old style guns. I run the gun between 50-60 psi. 3. If you are going to do vertical surfaces you need to be very careful and lay down light layers to prevent runs. Horizontal surfaces are no problem. The reason I got this gun was because my airless sprayer is nightmare to clean. This is best for the occasional door or cabinet. It lays down paint like glass if you are careful, just don't go for a heavy wet coat. If you plan on painting a house or a fence or something that requires a lot of coverage don't buy this, buy an airless, preferably not a cheapo. I have no intention of ever spraying any oil based paints through this gun, the cap set is just too big (2.5MM) and I don't recommend using this gun for thin materials, but for water based, thick paints, with proper preparation, it works really well, and the bonus is that it cleans up in five minutes.

Worked great. I agree with other reviews that the Latex paint must be thinned and strained in order to work properly. At first I didn't add enough water and had difficulty spraying a good even coat.

Bot this spray gun to spray my basement celling. Used black latex ceiling paint (ProMar 200) from Sherwin Williams. The gun performed perfectly and cleaned up very easy. I used a 1.8hp 26 gallon air compressor which was a little too small... I had to wait for it to recharge a lot. I would suggest renting a very large compressor if you dont own one. It sprays best at a consent 60-70 psi. I had to thin the paint with water. Once I thinned the paint, the gun sprayed a perfect mist .. no drips. Great DYI gun for the price. Very happy with the purchase.

I really wanted to like this gun, but it simply isn't built for the long haul. The overall build quality is very rough right out of the box. Despite being incredibly meticulous about cleaning and maintenance after every use, the seals failed much faster than they should have. It might work for a quick project, but eventually, it will let you down. Mine finally gave up the ghost when the internal seals gave out. If you're looking for a tool that lasts, I’d look elsewhere. This one is destined for the scrap heap sooner than you'd think.
