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.

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.

Is the pump on the 350 model supposed to run without trigger pulled in ? On other models it only comes on when trigger is pulled.

Asked by: MikeV
The Control Stainer 350 has an on/off switch on the side that controls the turbine. Stain will come out when the trigger is pulled. You can find more information and watch a video at this link, If you would like to discuss this or have further questions feel free to call us at 1-800-328-8251.

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.

I just purchased the 350 control stainer. It leaks from the can we have tried to tighten it. We have cleaned the seal but no matter what it bubbles up and leaks at mouth. Any suggestions.

If you have tried making sure everything is clean and tight. Then there may be something amiss with the components themselves and they may need to be replaced. If you could contact our technical support at 1(800)328-8251 they can troubleshoot to determine what could be going on and then go about getting your sprayer working as it should.

Is there an accessory to connect the sprayer to a 5 gallon container?

Asked by: Jo13
No that type of accessory is not available for the Control Stainer 150. Because of this unit being a HVLP(High Volume Low Pressure) sprayer, it requires pressure to build up in the can. This then pushes the paint up the tube to be sprayed. We have the Flexio 970 and 990 that have an include pump that feeds the material to the gun. Please contact our technical support staff at 1(800)328-8251 if you have any other questions or needs.
