Technically, this is really Part 4 of our Wall-Hanging Tool Chest build , but because I focused so strongly on waterborne finishes and HVLP (High Volume Low Pressure spraying), it received its own stand-alone title. I did some research, though, and found one (the Wagner HLVP Conversion Gun of Awesomeness) that I could connect to our air compressor for a fraction of the cost. But like many things in the workplace that don’t look as if they directly affect cycle time, cleaning your gun is probably the best time spent to speed up your next paint job. This HVLP sprayer with built-in turbine is a solid performer that can apply a better-than-average finish with properly thinned material.
QS-600WB – This new gun was built to Homestead’s specifications for our customers that wanted a great performing gun for both solvent and waterborne finishes that won’t break your budget. When it comes to cleaning the gun after spraying, it’s a real simple, easy and quick process. Then I disconnect the air hose and take the spray gun outdoors for cleaning, if possible. To allow folks that have smaller compressors (under 8 cfm at 40 psi) engineers designed a special type of HVLP called LVLP (Low Volume/Low Pressure).
The key, I believe, is understanding all the variables involved (some of which are adjustments to the spray gun) and having enough patience to make small adjustments and observe the results. There are techniques when slight arching or fading the paint gun are needed, such as when blending paint, but this is still kept to a minimum, as too much arching will cause the metallic to lay down differently.
It takes to get a car ready to paint, a paint gun is not a good thing to cut corners on. If I am spraying lacquer, I treat the gun just like a can and leave the finish in it until the next time I spray. But once you have the proper tip installed, the flow control then allows you to control how much liquid is being pushed out of the gun. It only takes few seconds to run lacquer thinner, in his case, to clean up the gun. The two cups have adapters so you can use both cup sizes with either gun, and included are rebuild/service kits, mini-regulator and cleaning brushes.
In five minutes I take my brushes to the parts and slosh in a quart cup of reducer and they are ready to go. this is easy and painless way to clean a gun. I have personally used HVLP systems from Fuji, Apollo and Graco, and all of them give similar results. The twist knob located on the back of the gun makes paint flow adjustments easier than with most other models we tried. Thorough gun cleaning removes unwanted paint coatings, but in the process, it also removes lubricant from the gun surfaces. At this current time the HVLP system would be the way to go. Thanks for your advise and pointers.
