Test airless paint sprayers before you paint. Sounds dumb, but it is the number one way to avoid a horrible mistake and a big mess to clean up! Without a doubt airless sprayers are the best way to lay down the perfect coat of paint easily and quickly. However, even the best maintained ones can surprise you! So start on a large piece of cardboard or plywood, and practice a few passes first.
Here is a quick run-down on the top 3 spray problems and their solutions.
Orange Peel Look: This is exactly what it looks like, the peel of an orange. Here is what’s happened. You don’t have enough air pressure, and you are getting more clots of paint than a mist. Adjust your pressure until you have the right mist.
Fogging AKA Overspray: This is the opposite of the first one; you’re getting a mist that just hangs in the air instead of landing on the surface. This is caused by too much air pressure. You begin to see why you test airless paint sprayers first, now don’t you? Getting the pressure just right takes fine adjustment until you get the perfect pattern. Now, there is another reason you may be getting overspray, and that is you are holding the spray gun too far away from the surface. Try moving closer.
Inconsistent Spray: If you’re getting weird drips and blank spots in your pattern, some speck of dirt or dust is clogging somewhere. It’s time to go back to cleaning a spray gun, and make sure there’s no blockage. This is why reversible spray tips are so popular. The tip reverses easily and quickly, without disassembly, and this is the most likely place for a blockage. Imagine this mess on your project instead of cardboard? It didn’t happen because you know to test airless paint sprayers first.
Air temperature, humidity, and paint all vary from day to day. Before you mess up your project with uneven spray, take a trial run on something like cardboard. That’s why you test airless paint sprayers every time before you start.
