Control Stainer 350 Sprayer

$ 99.99
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.

ControlStainer350 is rated 4.0 out of 5 by 1.
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.

Hello. Can I and if so how....use the Controlstainer 350 to paint Iron Gates?

Asked by: Orlando
The Control Stainer 350 is for thinner materials like stains, enamels, and polyurethanes. You would be better off with a Flexio model for painting. Try for a better look. You can also call us at 800-328-8251 for further assistance. Thanks for your inquiry!

Can this model be used for paints also?

Asked by: Jorge
It can but they may require thinning to work well. Paint doesn't hurt the sprayer, it's just too thick to spray well with this specific setup. Thin it about 10-20% with water and it should spray better. For more tips call us at 800-328-8251.

Can this product be used to spray varnish.

Asked by: Kitty
As long as it's oil based or water based it will work with Wagner sprayers. Varnish can be very thick and may require some thinning for a proper finish. For more info contact us at 800-328-8251.

It will not draw the paint from the suction tube, paint will come out if you have the gun side ways or upside down, that means paint manually gets pushed in to the suction tube

Asked by: CIhan
It's a problem of a lack of pressure in the paint container. Remove the suction tube. Hold it in front of you so that the dog leg points to your left side. Just below the white foam cup gasket, there is a 1/16" hole. Notice how the tube widens out to support the white foam gasket? The 1/16" hole is in that wider section. Can't see it? It's covered in paint and that's the problem. Air goes through that hole to pressurize the cup and force paint into the gun head for spraying. Contact us with any other questions at 800-328-8251.
