I don’t need anything fancy, but something that will spray furniture and get a good coverage. But when applying water-based lacquers with it, I can’t seem to come close to matching what my foam brushing achieves let alone the absolutely perfect finishes my buddy at the auto finishing shop gets granted his system costs 10x what mine did. Recently I have been leaving the aircap in a jar of denatured alcohol between uses – the alcohol keeps water base finishes from curing, which presumably will help keep the holes clear. Paint sprayers also come in many distinct variations and flavors”, which is typical of many simple tools like it.
I finally gave up on the gun since it didn’t produce the best finish and would often spatter and not spray enough paint. Some of those guns you are looking at cannot spray paint very well because you can’t get a big enough needle set. HVLP sprayers, on the other hand, use a large volume of air at low pressure to break up, or atomize, the stream of finish leaving the nozzle into a fine mist. The second part of the stain system is more similar to conventional stains because it has pigment. With water based finishes it is better to spray 2 thin coats rather than 1 heavy coat.
Conventional sprayers are pretty much outdated like the Ford Model T, but you can still use the rule of thumb of precision finishes with the HVLP and high-pressure, large-surface industrial paint jobs with the airless sprayer. They’re committed to fulfilling such high standards of excellence, as many other hvlp paint sprayer reviews would take note. Seems like it would give a lot of the benefits of a touch up gun (small size, easier cleanup etc) and the better (to me anyway) layout/feel of a conventional gun. Note: High humidity can cause the finishes to take longer to dry but will not harm the final finish.
In the end, it doesn’t save that much time, compared to rolling/brushing, especially for the cost, unless you have ideal conditions for using a sprayer. It has a heat absorbing section that keeps your gun from becoming to hot to handle during long spray sessions in the summer months. If you want to be able to effectively spray a variety of coatings from the gun including glue, you would want to consider a conventional spray gun. Our goal is to provide readers with information that will expand and fine tune their woodworking abilities. If a paint is to thin the colorant will separate from the binders, floating on top.
Saw this the other day and it looks perfect for furniture work – 200ml gravity fed pot (doubt I’d spray that much in a session), small conventional layout guy and it had nice balance. This conventional mineral spirits-based stain has a reddish-brown color and is meant to be applied like most consumer-grade stains: Apply with a brush, wait a few minutes, then wipe off the excess with a rag. Reading product reviews will also help you to get a better idea about the spray gun. Super easy to just add it right to the material canister full of lacquer and spray away!
The reason is that latex paint is generally made to be brushed, rolled or applied with airless spray technology rather than an air atomizing technology such as HVLP. Be sure to remove the airline then pull the trigger and let the finish be pulled out of the gun before you remove it from the cup. Squirt in a bit of the appropriate thinner, pull the trigger, and the gun is clean(airline disconnected).
It also adds another 6′ of hose to the original 25′ hose, which reduces the air temperature to the gun and can alleviate the problems associated with fast drying finishes. Toluene (tolulol) and xylene (xylol) have very little use in wood finishing, though they can be very effective for cleaning grease from metal. How much you need to thin the product will depend on the size of the turbine unit, available pressure, and the quality of the paint selected. In addition, many manufacturers now produce several water-based finishes that are not flammable.

This results in superior atomization, however it requires a larger compressor than most low cfm HVLP spray guns. Any material which has too high a viscosity will not be spray painted very well using HVLP sprays.
Unless you have a dedicated spray booth you’ll need to set up an area to work in. Use canvas drop clothes set on both the floor and as a backdrop to help stop overspray from getting where you don’t want it. The fine atomisation and wide spray fan of the SATAjet 100 B help achieve even material distribution, thus saving expensive labour time due to much reduced sanding effort. You could use a traditional spray gun that’s fed air from a compressor, but be prepared to fill the air around you with overspray (finish that goes in the air instead of onto your project).
At first glance, a conversion gun might seem like the answer – after all, many woodworkers already have a compressor and plenty of air hose around the shop. This changes the angle at which the finish is applied and therefore changes how much finish adheres to the wood because the angle at which you apply is one factor in how much finish bounces off the wood. Different paints require different spray tips and different pressures for proper application. It would also be fun if you are satisfied with the spray gun you are working with.
For example, if the suggested pressure is measured at the air cap (where the HVLP requirement of 10 psi or less is measured), you require a special cap with an attached gauge — for an extra couple hundred dollars. I just notice that when I scuff-sand the first coat of urethane, the dust has the color of the stain. Overspray can be overwhelming and must be considered more seriously when spraying paints as compared to spraying clear coat film finishes. Anyway I hope this has helped, feel free to comment on any of my suggestions, and happy woodworking.
And then to spraying, on with the pump, adjust the needle to reduce the amount of paint being forced through a few practice passes on a spare board and we are away. With the larger nozzles there is a fair bit of overspray and blowback plus they spray a heavy coat so you have to keep the gun moving. I just finished a batch of the Cub Scout crosses that we made (44 of them) and I knew that it was time to use the HVLP sprayer.
