Flexio 4000 Sprayer

$ 169.99
The FLEXiO 4000 stationary paint 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 outdoors 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 4.6 out of 5 by 32.
Rated 4 out of 5 by from Very easy to use This made painting my wooden farm fences easy. The long hose was great as I could move along quickly. The only change I would suggest would be have an adaptor so you could pull paint out of a pail.

Rated 1 out of 5 by from Terrible This has been a piece of junk from the beginning. I could never get it to spray an even coat, always had at least a little sputter that created an uneven finish. Especially for how much it cost, it really should be much better!!

Rated 2 out of 5 by from Poor spray pattern Bought product at Lowes after doing a great deal of research. A customer at Lowes recommended the Flexio 4000. I used it to paint an interior room with Sherwin Williams flat paint and it took a very long time. The best spray pattern was no more than 3 to 4 inches. I could have rolled the walls alot faster. Easy to use and clean, but I could not get a larger pattern and had to refill the container quite often.

Rated 5 out of 5 by from Great Product. I purchased this particular unit because I was looking for a spray gum that wasn’t too heavy. While you have to contend with being hooked up to the turbine hose, they guns are very easy to hold and use. I built a small wheeled platform to store the turbine on and it’s very easy to move around a room. While I have only used latex paint, both guns were very easy to clean with warm soapy water. The finished paint job came out very nice. Two coats of latex paint and a clear coat was easy to spray with just very fine sanding between coats. The finish was awesome. Good value for the money spent. Got mine at Lowes on sale.

Rated 5 out of 5 by from Surprised me I bought flexible 4000 with not a lot of high expectations. But when I opened it and sprayed a section of wall outside my house I was truly surprised at the ease of use and the coverage with such little amount paint. Also amazed at how easy to clean up. Glad I purchased.

Rated 5 out of 5 by from A Real Time Saver I received my Wagner-Flexio 4000 as a gift from my wife. This is an awesome sprayer! It's fast, it sprays even, limited amount of spray over, it's easy to use, it's light weight, and clean up is a breeze. Can't say nothing bad about this sprayer!

Rated 5 out of 5 by from Great sprayer Works great, just wish you could buy a larger container to hold whatever you are spraying. I sprayed nearly 300 feet of shadow box fence with semi transparent stain.Maybe Wagner will read this and come up with the accessories for a larger container. The reason I bought this is mainly to do smaller jobs. But my wife wanted the fence redone first. Happy wife...Happy life

Rated 5 out of 5 by from A Workhorse Surprised and pleased with the capability of this sprayer. Years ago I had a Wagner of comparable features. There is a world of difference in this newest one. It sprays evenly and will tackle big jobs.

I am painting my kitchen cabinets using Sherwin Williams ProClassic Interior Waterbased Acrylic-Alkyd. Will this sprayer handle this paint and can I use the detail sprayer to get smooth finish

Asked by: Scott1180
The Flexio 4000 will handle this paint. The Flexio 4000 comes with the Detail finish nozzle, the Detail finish nozzle is best used on your fine finish projects such as spraying cabinets, furniture, doors, trim etc. It will provide a smoother, finer finish than the iSpray Nozzle. Depending on your material, the Detail Finish Nozzle may require some thinning of your material in order to spray properly.

I've used your Flexio 4000 on multiple projects, no problems. Was spraying the walls in my garage and realized paint was coming out the tip even though I wasn't pressing on the trigger. I cleaned the gun, no difference. Any suggestions.

Asked by: Biker Bill
Try to tighten the retaining ring on the front. It's loose and allowed the nozzle to move away from the needle and when under pressure, it pushes paint out in a stream. For more help call us at 800-328-8251.

Would you recommend the 4000 or the 3000 to use to spray latex paint with the detail nozzle? I do know that it will need to be thinned, but  wondering if one sprays it a little bit better than the other.

Asked by: Scooterdoo
The only difference is that the 3000 is handheld and the 4000 has a separate turbine base from the spray gun. Both work equally well. To discuss further give us a call at 800-328-8251.

Asked by: RogerMD

Will the 4000 spray BLACK JACK Ultra Roof 1000 White Siliconized Elastomeric Reflective Roof Coating? It's a small project (Cardboard regatta Boat). I rolled some of this on yesterday and want to see if I can spray it if I thin it 10%

Asked by: Mark W Jones
We do not suggest using HVLP with elastomeric type paints. It's much too fibrous and thick and thinning it ruins the reason you paid extra for it.
