Questions & Answers


Do I need an air compressor to use this item

Asked by Cari April 28, 2018

No, the sprayer is electric.

can i spray a cealing with it

Asked by Manny October 5, 2017

Yes you can, you would want to make sure that you have the hole in the suction tube facing back toward you when spray. But we don't recommend pointing the sprayer upwards passed a 45 degree or else paint can get back into the motor. Please contact our technical support staff at 1(800)328-8251 if you have any other questions or needs.

Where the cup screws into the housing.rhe actual part came apart from the gun. How do I screw it back on

Asked by Nate September 25, 2017

If you mean that the pump housing separated from the gun, it's the tightening ring that holds it all together. Check you manual for the exploded view and directions on how to assemble the gun. Or you can call technical support at 800-328-8251.

Can this handle water based or latex paint?

Asked by Kris August 29, 2017

No it's to thick and will clog up

Does this spray lacquer based material?

Asked by Laborer August 5, 2017

Our Wagner line of sprayer can spray material that either cleans up with mineral spirits for oil-based or warm soapy water for water-based. They are not able to handle any solvents. Please contact our technical support staff at 1(800)328-8251 if you have any other questions or needs.

Do you have to thin paint with this model if so witch model is it that you dont have to thin out

Asked by Aldridge75 July 7, 2017

The Power Stainer 5.4 GPH sprayer is designed for thin-bodied materials like stain, sealers and oil enamels. We don't have a sprayer where we can say it can spray any paint unthinned but our Flexio line of sprayers is designed to handle thicker materials like latex paint and paints and primer. Our website, https://www.wagnerspraytech.com/ under products choose Flexio, will have lots of info on the different models that we carry. Please feel free to contact our technical support staff at 1(800)328-8251 if you would like to discuss this in more detail or have any other questions or needs.

Can I use this to apply a stone sealer?

Asked by Michele October 31, 2016

Some sealers recommend that it be applied with a brush, roller, or pump sprayer. The Power Stainer may spray it but it may not give you the finish you want. If you would like to call us at 1-800-328-8251 with the manufacturer’s application recommendation we will assist you.

Does this paint sprayer require a compressor or is it simply electric-powered?

Asked by Steven October 7, 2016

Our sprayers are all electric.

Where can I buy a replacement canister

Asked by Cheryl September 23, 2016

You can order it through your local Home Depot or call us directly at customer service. You'll find part numbers in the owner's manual.

Not what I was expecting
Bought this a year ago for doors and trim. Just now used it for trim work. Better off painting by hand. Sprayer will spray then cut out and spit globs of paint spray and cut out. I filled the jug thinned it and still the same thing. Now my coworker just bought one and it does the same thing starts to spray then cuts off and spits globs of paint. Not a smooth constant spray.

The Power Stainer is not suggested for thick latex paints.The right tool for the job is our Power Painter series. They will do great with thicker latex paints. Take a look here - https://www.wagnerspraytech.com/?s=power+painter
poorly designed
There must be a better product somewhwre on the market. this sprayer is very fragile, needs constant maintenance and cleaning, and works very inconsistently.

I bought this sprayer to stain a fence. I accomplished the job in about 4-5 hours of work, so I got what I set out to do. However, at the end of the day, the bottom cap where the stain went in the sprayer kept detaching itself from the suction tube. I chucked the whole thing in the trash can after the job was done. Basically, this thing is a one-time use.

Wagner power stainer 5.4GPH
Had a good amount of trouble getting sprayer to operate. It constantly dripped even after adjustments made. Cleanup due to drips was a great amount of time. I would not recommend this product and I am glad I did not go for the more expensive model.
by Kenkuski
Response from Wagner Spray TechDec 8, 2016
It's always a good idea to spray some water through a sprayer the first time you operate it after storage. It's a good indication of any possible problems. Dripping is usually caused by the locking ring not being tight. All of our sprayers come with a one year warranty and technical support is available to help you resolve these issues. Call us at 800-328-8251. WagnerSprayTech
Great Tool
Works extremely well! Great product! Make the job quick and easy!
Response from Wagner Spray TechOct 10, 2016
Thanks for saying so. WagnerSprayTech
Waste of money
Very disappointed in this sprayer. It worked for maybe 5 minutes then just quit spraying. Took everything apart and cleaned each part and when I put it all back together now all it does is just hum.....Spend your money on paint brushes it will take a little longer but less hassle....Another Made in China piece of junk

Don't waste your money. Either go all in or do it by hand. This in between garbage wouldn't even spray primer without getting jammed. Seriously. Behr primer that I thinned with water was still too thick.
by Alyssia
Response from Wagner Spray TechAug 8, 2016
I’m sorry you experienced issues with the Power Stainer. It will spray some stains and even some paints. Primers typically dry very quickly, the piston inside the sprayer moves so quickly that it creates a lot of heat, that heat causes the primer to dry even quicker which inhibits the piston from moving efficiently and will eventually cause it to freeze and stop spraying. Adding paint conditioner, which will slow down the dry time, will help. Please call technical support for further assistance. WagnerSprayTech

On clearance good price for my fence
I bought this on clearance for 40 bucks. I feel that for using this for Stain on my wooden fence but I don't care that much about it being a huge investment so I would recommend it for anybody for small projects and for 40 bucks.
Response from Wagner Spray TechJul 5, 2016
Thank you for your comment. Good luck with your fence staining project. WagnerSprayTech
