Flexio 4000 Sprayer

$ 169.99
The FLEXiO 4000 stationary sprayer is perfect for longer painting projects, with less weight in your hand, because the motor is housed in the base on the ground. It has variable speeds for cutting time and effort on painting projects and can paint a wall 11 times faster than a brush.

The 4000 comes with 2 different nozzles – one for painting multiple rooms, decks and sets of furniture. The other nozzle for fine finishing on cabinets and trim. The new nozzle design delivers an improved spray pattern and adjustable control with less mess and overspray.

It has the flexibility to spray indoors and out with the power to spray unthinned paint and stains with full coverage. Cleaning is faster than a brush or roller with just a few removable parts that separate and rinse clean.

Covers an 8’x10’ surface in minutes:
-Stain: 1 minute
-Latex: 5 minutes

Flexio 4000 is rated 4.9 out of 5 by 21.
Rated 5 out of 5 by from Wagner means quality painting I recently bought a flexio 4000 sprayer, I had a few house projects I wanted to spray, NO BRUSH/ROLLER marks, I did my research, and everything I read said this was what I needed for ALL my spraying needs. The flexio 4000 did not disappoint! My hand built Mantle came out with exactly the finish I wanted FLAWLESS!! Trust me, when it says Wagner it’s quality spray equipment!

Rated 5 out of 5 by from Doesn't get much better! Bought the 4000 a few weeks ago and painted my utility building today. A job that would have taken me at least 6 hours took about an hour. I used a very thick latex paint and the unit had no problems. I cleaned everything outside using water buckets and it took me about a half hour. Painting is no longer something to dread!

Rated 5 out of 5 by from Flexio 4000 I bought this sprayer specifically to apply an oil based perservative to 200 feet of redwood fencing in my back yard. I have an airless sprayer but wanted to avoid the clean up required when I use an oil based product. I also want a sprayer I can use to repaint the upstairs bedrooms. I was entirely pleased with the performance of the 4000 and the ease with which I was able to get it clean after the job was finiished. I am a dangerously skilled home owner and I must say this is one of those rare products that works just as the manufacture claims!

Rated 3 out of 5 by from Uses alot of paint This is so much quieter than the old style however the paint doesn’t go as far with this one. I do like it but it’s more costly to spray with this one then it is with the older model

Rated 5 out of 5 by from Very pleased. Bought this to repaint my kitchen cabinets. Used the detail finish nozzle, had to thin paint a little but it turned out fantastic. Low overspray made it great for touching up trim too. Clean up was a snap.

Rated 5 out of 5 by from Simple and well thought out I was intimidatedat first to use a sprayer. This tool made my first attempt look like a professional finished my work. It’s simple to use. Simple to clean. Spray is consistent and accurate. Surprisingly small overspray. Would but this model again in a heartbeat.

Rated 5 out of 5 by from Excellent spayer Never used a paint sprayer and was a bit leery about buying one especially since a lot of reviews are mixed. However I couldn't be happier with the Wagner Flexio 4000. It is easy to use and easy to clean and does a great job of laying down a smooth coat of paint. Very pleased.

Rated 5 out of 5 by from Excellent Sprayer for the Price I got the Flexio 4000 and love it! It's so handy to have around and the finish quality is amazing. So far I've only sprayed furniture and doors outside and the finish has been amazing. I've used lots of sprayers in the past and this one is for sure one I would recommend. I admit that for a beginner there probably is a bit of a learning curve with getting the product to apply just right but once you get the settings perfect you are unstoppable. I really can't imagine not using a sprayer for projects like furniture and many other things and this one didn't disappoint at all. I used both brand new paint and paint that had thickened a bit with age and anything I used worked beautifully. I love that it's small but has a lot of nice features that you find in the larger and more expensive units. You will not be sorry that you purchased and say goodbye to long and tedious painting projects.

Is this available in Canada? Or can it be shipped here?

Asked by: Noramcm
The Flexio 4000 is not available in stores in Canada but you can try Lowes.com to order online. Otherwise you can access the Flexio 890 which is very similar except it comes with a storage case. It will do the same jobs as a 4000. Thanks for contacting Wagner!

Why can't latex paints be used in the detail sprayer of the 4000? Nothing tells you this until you get into the instructions (after you've bought the sprayer).

Asked by: Mike71k
The Detail Finish nozzle is designed to get a smooth pattern when spraying thinner finish materials. It doesn't automatically mean you cannot spray latex paint through it. Just expect to thin it out quite a bit to get an even pattern. Latex paint is generally associated with getting good coverage and a protective coating as opposed to a fine finish. Go ahead and give it a shot with the Detail nozzle though, if it's thin enough you may get a nice smooth finish. You can also call us at 800-328-8251 for any further questions.

What is the difference between 4000 and 5000 How much noise do they make is it less than the models with the pump in the handle I can’t stand the noise on most all in one hand held models

Asked by: Alton
The 4000/5000 are very similar units. The 5000 has an air on/off switch at the gun and comes with a hard plastic storage case. The 4000 has a 3 foot longer hose but then everything else is the same between the two models. They make the same amount of noise as the handheld models but since you can set the turbine 12 feet away it wont seem as loud as the handheld models. For more information give out Technical Service a call at 800-328-8251, thanks for contacting Wagner!

Wondering if this Flexion 4000 can be used with a hose in the paint can. I'm almost certain it can't but making sure before I decide which to purchase. Thank you

Asked by: Jardineo
The Flexio 4000 will not siphon from a can or bucket of paint. It can only use the material cup provided with the unit.

I have a flexio 4000 can I spray indoor/outdoor latex paint in the detail finish nozzle? And dose the iSpray nozzle have a fine smooth finish?

Asked by: KJ cop
The detail finish nozzle is generally for thinner materials than latex. You can try it but I suggest thinning the paint before hand. The I-Spray nozzle puts on a finish like a roller would leave. Not completely smooth. The detail nozzle is the one to use for a fine smooth finish. For further help you can contact our Technical Service at 800-328-8251.

Can you use this sprayer pulling paint from a gallon or 5 gallon can?

Asked by: Mlight
The Flexio 4000 will not draw paint from a can/bucket. Our Flexio 970 and 990 however will draw paint from a can/bucket. Contact our technical service at 800-328-8251 for more information.

what the diffrent flexio 4000 and flexio 690 ?

Asked by: moshe
The Flexio 4000 is replacing the Flexio 690 and the only difference is in the iSpray front end nozzle. It has fewer parts, easier clean up and a better spray pattern. Otherwise, they are the same. Once the 690's are sold out the 4000's will fill the shelves. For more help call 800-328-8251.
