Features #
Suitable for both indoor and outdoor painting this handheld spray gun kit is both powerful and flexible.
A big selling point is Wagner's commitment to its motor efficiency. The 590 is likely both quieter and lighter than any spray gun you've used in the past. It is 50% quieter and 20% lighter than traditional airless sprayers. Weighing in at just 4.0 lbs and putting out just 65 dB of noise (at low settings) it packs some impressive engineering.
So what sets the FLEXiO paint sprayer apart from other models?
X-Boost Power Dial #
Performance-wise it is aided by a new patent for Wagner. The X-Boost Power Dial is unique to the FLEXiO range and offers painting speed and coverage that’s hard to match. The technology automatically adjusts the air pressure produced by the turbine motor so that you have complete control over any coating.
By keeping the air pressure high, the sprayer will drop less material, and the finish will be noticeably smoother. This is especially important for thicker paints that require more turbine strength.
The Power Dial has 10 settings to give you ultimate control over the material flow. The paint spray pattern can be adjusted to horizontal or vertical and wide or narrow.
iSpray Technology #
This feature improves coverage by improving the airflow of the gun. By improving the turbine power efficiency, this Wagner FLEXiO paint sprayer can deliver more power and increase airflow delivery. This results in smoother finishes with less material being wasted.
How well does it deliver paint? #
This FLEXiO unit is suitable for all spraying situations. It's perfect for exterior surfaces, interior walls, and fine finishing (using the special detail nozzle).
It can spray unthinned interior/exterior paints and stains with its X-Boost turbine.
With two included nozzles, it can handle a wide variety of paint jobs.
- iSpray nozzle - suited best to unthinned paint and wide surface areas. This nozzle is for general coverage where you don’t need to be too careful.
- Detail finish nozzle - for the fine finishes and tricky sections. Includes vertical, round, and horizontal pattern positions.
Thanks to the adjustable control, you can spray unthinned coatings. And most importantly, it offers full coverage and low overspray to make your painting projects easier and more enjoyable.
It can spray up to 8 gallons per hour of material which is as much as three times quicker than some conventional paint sprayers.
The adjustable paint flow settings let you match the paint delivery to your coverage speed and project size.
It can’t all be good right? #
Sadly, no, this Wagner FLEXiO 590 review is not perfect. A major bone of contention for us is the learning curve. This is not the paint gun for beginners. Its variety of settings will leave the inexperienced user feeling confused, and there’s a high likelihood they’ll experience some overspray in the beginning due to its power.
There’s also a complicated screwing system to detach the container from the gun. It’s not intuitive, and you’ll probably need to consult the manual to crack it.
It takes a bit of practice to master the Wagner 590.
Pros #
- It’s fast!
- Lighter & quieter than most
- Quickly assembled
- Adjustable flow control
- Special nozzle for fine finishes
- Handles thick paint easily
- Great paint coverage
- Lock-N-Go split design for quick nozzle changes
Cons #
- It’s a bit bulky
- Comes with a short power cord
- Steep learning curve
- It’s a bit pricier than most traditional HVLP guns
Flexio 590 Sprayer FAQs #
1. What’s the difference between Wagner Flexio 570 and 590 Sprayer? #
The 590 has an adjustable dial for additional speeds, however, the 570 has just two-speed settings. The 590 also sprays more gallons per minute and comes with a 2nd nozzle for a more detailed finish.
2. Will this spray latex primer? #
Yes, it will spray latex primer, and you don't have to thin it. Most users have had a good experience when using latex. All you need to do is turn up the dial.
3. Can it use exterior latex paint? #
You can use oil-based or latex paint, primer, or stain. If you have issues with globs of paint, call the troubleshooting number, and they'll walk you through how to correct the problem.
However, note that you will need to do a long-winded cleaning if you want to maintain it in good working condition.
4. Would this be good to paint a house? #
It's a great time-saver compared to most other guns due to its power delivery. You get a wide spray for large surfaces and a professional finish and look.
5. What are some common troubleshooting tips? #
If the sprayer doesn't produce any pressure in the container, you should tighten it because it's probably loose.
6. Are replacement parts readily available? #
Yes, the majority of the parts for the 590 are available. Most parts are available online from sites like Amazon, or you can e-mail Wagner for an official list of suppliers.
7. Is it easy to clean? #
FLEXiO 590 sprayer maintenance is relatively simple. It comes with a cleaning brush, and the parts are easily separated when it's time for cleaning.
8. Can it be used to paint a ceiling? #
The only problem here is that it mustn’t be tilted more than 45 degrees. This is because the paint may enter into the fan mechanism and ruin your device. This poses a risk but it’s still possible to paint ceilings due to the adaptable spray modes.

The Bottom Line #
In our opinion, the Wagner Flexio 590 paint sprayer is definitely worth the extra money it retails for, but only if you are an experienced paint sprayer who needs something with faster paint coverage.
Its multitude of settings and customization options put it out of reach of the beginner or first-time user, but for those with the “know-how,” this gun is a worthwhile investment.
The FLEXiO 590 allows you to paint whole walls in no time and increase your efficiency like never before. In addition, it is delicate enough for a detailed finish and has a two-nozzle system that works well.
It doesn't come at a cheap price, but if you're a regular user of paint sprayers, then it's a worthy investment as you'll get more done faster. It's a great piece of equipment.
In conclusion, the Wagner FLEXiO 590 reviews very positively, just not for everybody.
