PaintWIZ Paint Sprayer Review

An Easy-to Use Affordable HVLP System for Avid DIYers That Delivers Stellar Results.

PaintWIZ Paint Sprayers

PaintWIZ Paint Sprayer



If you plan on painting the outside or inside walls of your house this year, or perhaps the deck, fencing, or other outdoor structure, or even those tired looking kitchen cabinets – then you might want to consider purchasing a paint sprayer. With a paint sprayer you'll apply the finish much faster than with a brush or roller, complete the job quicker, waste less finish, and end up with a better looking job. You're not limited to paint – you can also spray oil or oil/varnish blends, shellac, varnish, and lacquer.

The PaintWIZ is a new line of sprayers from Fuji Spray, a leading manufacturer of spraying equipment. The PaintWIZ is specifically designed to provide avid DIYers with a lightweight, convenient, and affordable sprayer that uses HVLP (High Volume Low Pressure) technology.

There are two models of the PaintWIZ. The PW25000, which I tested, consists of a turbine and a spray gun, while the PW25150 is a hand-held sprayer.

Both PaintWIZ models use HVLP technology. Essentially, this means that air (and the finish) is forced out of the spray gun nozzle at a very low pressure – not more than 10 psi (pounds per square inch). A non-HVLP sprayer (typically called a high pressure sprayer) has an output pressure of around 50 psi. The HVLP sprayer gives a gentler spray that is easier to control, with a much greater proportion of the finish ending up on your project, and not forced back onto you, or into the atmosphere. To learn more about HVLP read "High Quality Finishing With HVLP".

Basically, the process involves six steps:

  • Install the right size nozzle for the finish being sprayed
  • Select the appropriate spray pattern
  • Check the viscosity of the finish, and thin as required
  • Strain the finish
  • Test spray and adjust the flow volume
  • Clean the equipment

The PW25000 Turbine System

The PW25000 consists of the turbine (A), a spray gun (B), two sizes of spray nozzles (aka spray tips) - one for thin and another for thick finishes (C), two sizes of containers (aka cups) for the finish (D), a 20-foot hose (E), 3 mesh strainers to filter the finish (F), a viscosity cup to determine whether the finish needs to be thinned (G), a brush to clean the nozzle and air cap (H), and a shoulder strap so you can support the turbine hands-free (I). A user manual is also included. When not in use, the spray gun can be conveniently stored in the turbine.

All the components of the PW25000 are made of a high impact ABS plastic, which makes clean-up quick and easy, plus there's nothing to rust.

Washable air filter

The turbine, equipped with a 4.7 amp motor, generates a high volume of air and sends it to the air gun under low pressure via the hose. On the top of the turbine housing is the on/off switch, and at the back of the housing is a filter that you'll need to regularly clean, as a dirty or clogged filter can cause the turbine to overheat.

The business end of the spray gun

The spray gun is where the action takes place. The nose of the gun consists of a collar (A) that holds the other components in place – the air cap (B), which is also referred to as the 'spray pattern selector', and the nozzles (C, D). The PW25000 comes with a 2.6mm and a 1.8mm nozzle (the measurement is for the diameter of the hole in the center of the nozzle). You'll use the larger nozzle for thick finishes – primarily for acrylic latex or alkyd paint and primers – and the smaller nozzle for thinner materials such as oil or oil/varnish blends, shellac, varnish, and lacquer.

Assembly is straight forward

The air cap and a nozzle need to be installed into the nose assembly prior to using the spray gun. I found it easiest to place the nozzle onto the back side of the air cap, insert both into the front end of the spray gun while depressing the trigger, and then screw on the collar. There is a small nib on the rim of the nozzle that you need to align with an equally small recess on the barrel. It's a bit awkward to do, but ensures the threads match up and prevents fluid leaking. You're now ready to adjust the spray pattern.

The air cap controls the spray pattern

By adjusting the air cap you can get three different spray patterns – horizontal, vertical, and round. To change from one spray pattern to another you don't need to loosen the collar, simply turn the air cap to the desired position. Small icons embossed on the barrel of the air gun point the way.

I use the vertical spray pattern (middle, photo above) most often, as I find it easier to move the gun horizontally, side to side. For tall, narrow surfaces I sometimes switch to the horizontal spray pattern. On small projects (knobs, handles, and the like) I use the round pattern (you'll need to reduce the spray volume when using this pattern by adjusting the fluid control dial.

Try all three spray pattern configurations so you have a good idea of how they function, and what works best for you.

Adjust spray volume with the fluid control dial

You control the volume of finish coming out of the spray gun by adjusting the dial on the trigger. Dialing it upwards increases the volume of finish, dialing it down decreases the volume. If the volume is set too low the spray will be weak and it may take longer to apply the finish. If the volume is too high you can get too much over spray. It takes a bit of experimenting to find the right volume setting. Try to set the volume at the lowest setting that gives you a solid fan pattern.

Disassemble the head for easier cleaning

It's crucial that you clean the air gun after each use. Fortunately, the process is quick and easy with the PaintWIZ. There is a release button on the top of the air gun that enables you to separate the nose assembly from the gun handle. All you need to do then is disassemble the nose piece and wash it thoroughly – use water for water-based finishes, and mineral spirits for oil-based finishes.

Check the viscosity (thickness) of your finish

Before loading up the spray gun with a finish it's important to measure the viscosity of the finish – to determine if it's the right thickness so that it atomizes correctly. This is particularly important if you purchase a finish that is meant to be brushed on rather than sprayed, which is true of most consumer house paint sold at paint stores and hardware centers. A finish that is too thick will come out of the spray gun slowly and likely produce a lot of tiny droplets that result in a bumpy finish. At the proper viscosity the spray pattern should look like a fine mist, which will result in a smooth finish. 

To measure the viscosity begin by stirring the finish (as directed by the manufacturer), and then submerge the viscosity cup in the finish. Lift it out and begin timing the flow until the finish runs out of the cup. Consult the user guide that comes with the PW25000 (or supplied by the manufacture) for the recommended run-out time (typically measured in seconds). If required, thin the finish using the appropriate thinner. You want to use the least amount of thinner needed to get a well atomized spray pattern. Begin by adding thinner in a set amount – 10% is a good starting point – and redo the viscosity test. Repeat until you reach the recommended run-out time. Remember to record the amount of thinner you use for the specific finish.

I strain the finish after I do any thinning, though you can do it before. Straining removed any contaminants or dried bits of finish, and is particularly important to do if the container of finish has been previously opened and used.

Shoot straight!
 
A critical key to getting a good finish is proper spray technique. You'll get better results with less frustration if you practice using the sprayer before undertaking your first project. To begin, fill the spray container with water and spray on a large flat surface (garage door, side of your house, sheet of cardboard) to learn how the gun works and to practice your spraying technique. Typically, you want to keep the spray gun at a 90° angle, about 8-inches from the work surface, and overlap each pass by about 25%. You should also test spray each new finish that you purchase, and record the viscosity time on the container for future reference. For more information about the proper spraying technique, read "The Basics of Spraying".

Uniforrn even finish with no sags

I tested the PW25000 with acrylic latex paint, thinned to an 85 second run-out time, as I prefer to spray fairly light coats. I was very impressed with the results – the PW25000 delivered an even, uniform coat of paint, and I didn't experience any runs or sags and virtually no overspray. I also sprayed a General High Performance water-based varnish, thinned to a 40 second run-out time, with very good results. Getting a great finish will take some practice, so don't rush into a major project until you've pulled off a couple of smaller projects and are comfortable with how the sprayer works, and you've fine-tuned your spraying technique.

The PW25000 is an easy-to-use, economical sprayer that you can use for just about any painting, staining, or general finishing project you need done around the home – interior and exterior walls, doors, outdoor furniture, decking, fencing, and the like. If you're a hobbyist woodworker who only might need to spray once in a blue moon, the PW25000 just might be the tool. It obviously won't deliver the same high-level of finish as a professional HVLP system like one of the Fuji Systems, but for the occasional wood finishing job, I think you'll be quite pleased with the results.
