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 4.8 out of 5 by 29.
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.

Rated 3 out of 5 by from Good and bad: a mixed review Okay here is my review: (no videos, or pics) For painting speed and for coverage this thing is great. Its fast and it lays on a good coat of paint. It is also super easy to use, not as scary as I had anticipated. I didnt have to thin the paint (latex primer) and I had no trouble with the nozzle clogging. But (here comes the bad part) its messy. Super messy. Everything is covered in either overspray or dry paint dust. And that coverage? Takes hours to dry. I painted primer at 1115, and it's still wet 4 hours later. Unheard of. I paint all the time and primer is usually almost instantly dry. The cup of paint has to keep being refilled which slows down the process (might be worth getting the one that sucks the paint right from the gallon.) The set up and prep is very time consuming. The paper, the plastic, the taping, etc. Its extensive. Or your stuff will be covered in spray. Cleaning the machine parts is a pain unless you have a big slop sink or somewhere outside to do it. Which I dont... So mixed reviews here. I would actually return it, because i dont think i will ever use it indoors again. But i have some outdoor stuff to paint, and i am redoing my dining set, so i think i will keep it for outdoor painting exclusively. I imagine it will make quick work of the chair and table spindles and legs.

Rated 5 out of 5 by from Flexio 4000 I purchased a 10' X 12' storage building. I was instructed that I needed to paint it within 60 days of installation to be covered by the warranty. I purchased the Flexio 4000 from Lowe's to do the job. I was very satisfied with its performance.

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.

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.

Do the 3000, 4000 and 5000 all have the same power, or is one more powerful than another, and does the hose length being longer affect the power in anyway?

Asked by: West Coast
The 3000 is slightly less power than the 4000 & 5000. About 3 psi compared to 3.8 psi. and the hose length does not make a difference at all between 11' and 16'.

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!
