The Wagner Control Stainer 350 sprays with speed and consistency. Projects like garage, large decks, walls and exterior trim get done with less work and low overspray.

With a range of materials from semi-transparent stains to some paints, the flow can be increased or reduced for maximum control of how much stain or paint goes on and where it lands.

When the project is done, the Control Stainer 350 cleans up quick; the nozzle assembly separates from the turbine and cleans up in less than eight minutes.

Rated 5 out of 5 by from Worth every penny I purchased this prior to staining my deck with solid color stain. I was apprehensive about the purchase but found the sprayer to be easy to use, easy to clean, and a huge time saver especially on the railing. Worth every penny

Rated 3 out of 5 by from Sprayer has limited use The advertising states some paints. I used the sprayer twice with "one coat" water based paint and thinned to maximum as instructed by paint label. The first time was a small job - worked fine. The second time was longer. The pump section became quite warm and the paint started to collect on the front of the nozzle - constant removal required. I would not recommend this tool for thick paints (such as "one coat"). The instructions should also state a viscosity range for the paint or stain.

Rated 1 out of 5 by from Worst product and Company ever I bought this gun a couple of months ago and only used it once the next time I tried to use it, it suddenly stopped working I constantly was calling Wagner about it and they kept saying to clean out the tube that sucks up the paint I kept saying I did I even let it soak and it still wasn't working they just refused to give me a new gun with my warranty I will never buy their product again and I wouldn't recommend anyone else

Rated 1 out of 5 by from Suddenly decides to malfunction... I bought this sprayer for its small compact size and ease of use on small projects. I build planter boxes and use about an 1/8 of a gallon per box. On the first 6 boxes, cleaning after each box, everything works well. But, now I used it on four (4) large planter boxes 54" x 27", with vertical legs of 30". I did all 4 boxes at the same time. It took about 1hr of continual use. I was switching from vertical to horizontal continually. I noticed the Jets of air coming out getting hotter and hotter, but I can't stop...gotta keep going. After 45 min of spraying and switching horizontal to vertical, the setting was on fine spray and no.1 volume; the gun decided to spray wide with lots of volume. I check the sprayer and it narrow on 1, but the sprayer is doing wide on like 4. Lots of stain is going everywhere... Now my boxes have more stain in areas they don't need it and they look like dirt!! The gun gets hot and decides it will spray whatever the, you know what, it wants to spray after 45min of continual use... I will not recommend this sprayer for small projects that require stain on planter boxes. My $2,000 order of boxes look like a kid did them, because the sprayer decided to do its own thing...

Rated 4 out of 5 by from Works great for large jobs, but... I purchased this product specifically to apply semi-transparent stain to a very long cedar fence with total surface area of about 3600 square feet. The sprayer was easy to use, and, most importantly, applied the stain evenly over the spray pattern. In total, the job took less time than I anticipated and the results look very good. The biggest downside to the 350 for large jobs is its small (1.5 qt.) paint cup, which is only good for a few minutes of spraying. My job required 12 gallons of stain, which means I had to refill the cup about 32 times over the course of the job. In fact, I probably spent more time refilling than I did actually spraying. I understand that a much larger cup might make the unit too heavy to be easily handled, but it would be great if Wagner offered, at least as an optional accessory, a cup that could be refilled quickly without removing it from the sprayer (perhaps using a hose and hand pump). Less seriously, while the working parts of the sprayer are fairly easy to clean (at least for water-based stain), the plastic exterior has a lot of nooks and crannies where it's difficult to completely remove dried-on stain. This is particularly true for the turbine section which obviously cannot be immersed.

Is it possible to order a replacement motor section (back half)? My sprayer no longer powers on. It is a Control Stainer 350

Asked by: Joe203
We do not sell just the turbine part of our HVLP sprayers. We do have reconditioned models, at a discount that may work just as well. Call us for help at 1-800-328-8251.

HD states this is compatible with stains AND interior/exterior paints....Should you contact HD to change their description?

Asked by: Andy34
It also says "everything from semi-transparent stains to thin bodied paints." Meaning, paints will work as long as they're thin enough. For more help choosing the right sprayer for your project call us at 1-800-328-8251.

How much do I need to thin exterior latex paint for this gun? Ratio to a pint please.

Asked by: Andy34
The Control Stainer 350 is designed to spray stain, not latex paint. You should look at one of our Flexio sprayers like the 3000 or Flexio 5000. If you need further assistance feel free to call us at 1-800-328-8251.

First time user. Just bought it yesterday, set it up. Before I added the paint I wanted to turn it on to see how loud it would be. And notice that hot air comes out from the front. Is or will that be a problem? 

Asked by: Cruzin_86
The Control Stainer 350 HVLP sprayers uses a turbine to produce airflow for atomization of your paint. Air flows freely and when you pull the trigger completely it adds paint. Lots of spraying videos to see here. For more application tips call us at 1-800-328-8251.

After spray painting most of my fence (first-time use), trigger control was ineffective and could not stop paint flow.  After shut power off - paint streamed out.  Is there a fix?  Brand new purchase

Asked by: Anonymous
Most likely it's because the retaining ring on the front of the nozzle is loose. When the threaded ring on the front, that holds it all together, loosens, it allows the nozzle to move away from the needle, breaking the seal and allowing paint to stream out when under pressure. Please try to tighten the threaded ring on the front of the sprayer. If this doesn't solve the issue, please contact us for warranty help at 1-800-328-8251.

I need to use this sprayer out of my truck, using a power inverter. How many watts do I need to run this sprayer

Asked by: Mickeyreategui
We don't recommend using a power convertor with our sprayers as it will prematurely wear the turbine. In this case 900 W minimum power to operate your sprayer. For more help call us at 1-800-328-8521.

Can I use this with transparent stain for my new fence?  Specifically, Behr Transparent Waterproofing Wood Finish?

Asked by: mikechm
Yes the transparent stains will work well with the Control Stainer 350. Power at max and stain flow lower for better atomization. Call for more application tips at 1-800-328-8251.
