How To Clean Dried Latex Paint From Paint Sprayer In 7 Steps?

Last week I was painting the interior of my bedroom. It is a small room (8’x10′) and it took me two days to paint the entire room including the door, windows, baseboards, light switch covers, and trim around the ceiling.

After finishing each section I would turn off all the power in that room including both wall switches and the light switch before I did any cleanup. However, when it came time to start cleaning up the paint sprayer, I discovered that there were paint spots on the floor where I had walked while moving around my ladder during painting.

I bought a Graco Magnum Project Painter Plus for this job. It’s one of the more popular models and I bought it because of all the accessories that come with it.

In addition to the four nozzles, 50 ft hose, and 20 oz paint cup you get a turbine tool for cleaning with a white scrubbing pad on one side and a gray pad on the other side.

The white side is supposed to be used for washing or rinsing while the gray side is for scrubbing. You are also supposed to wear latex gloves while working with the tool.

Since this paint sprayer didn’t come with any cleaning instructions, I used what I had read online about using it for painting cars and other large areas since that’s what people use these types of paint sprayers for.

7 Steps For How To Clean Dried Latex Paint From A Paint Sprayer:

  • Step 1: Disconnect the paint sprayer from both sides of the power cord.
  • Step 2: Rinse out the paint cup and clean it thoroughly to remove all traces of dried paint. You can also use a paper towel or rag for this step since you don’t want to use anything that could scratch the inside surface of the cup if you use something too abrasive. I used a rag that came with my shop vac and it worked just fine.
  • Step 3: Fill the paint cup about half full of warm water. Insert it back into the unit and turn on both switches to start a cleaning cycle. Make sure you hold onto the cups when doing this since they don’t have any “stops” to keep them from moving around while cleaning.
  • Step 4: When the cycle is done, disconnect the paint cup and use a rag or paper towel to wipe out any excess water. If you don’t get it all out at this point, you will notice later when your next load of paint comes out too thin. The manual states not to try to clean the cup when it is attached to the paint sprayer so you will have to do this step each time.
  • Step 5: You need a container large enough for both cups and your turbine tool if you choose to use that (I didn’t). Fill the container with warm water and gently place both of them into the water. I chose to submerge both cups and the turbine tool at this point instead of just rinsing them out. I turned it on for about 30 seconds so that all parts were underwater, not just spraying or dumping water over the nozzles.
  • Step 6: After removing both cups from your container, use a rag or paper towel to wipe out any excess water. You don’t want to leave that in there since it will dry and cause problems when you start painting again.
  • Step 7: Unplug the paint sprayer from the wall, disconnect the turbine tool (if used) leaving one side connected but turned off, and retract all three sections of the hose by rolling them up.

My paint sprayer came with a bag for storage so I put all of my accessories in the bag when finished cleaning. The manual states that you should keep the turbine tool assembled until use to prevent any damage to internal components when transporting it, but I don’t see how that would cause any problems since it is stored in its own container during transport.

It would be nice if the Turbine Tool had some type of stop/release mechanism on it so that you don’t have to hold onto both parts when cleaning, but it’s not really necessary.

Also, I wish the instructions for how to clean my paint sprayer came with the unit instead of having to go online and search for it since most people wouldn’t think about the process without seeing the manual.

I like my Wagner Flexio 590 Sprayer and am looking forward to using it on my next project. It did everything I expected it to do, giving me a smooth finish with no paint runs or drips (and no need for primer).

How to unclog a paint sprayer hose?

Question: Hi, I was using a paint sprayer and it plugged up and now it will not spray, can you tell me how to unclog it?

Answer: It sounds like the paint is clogging in the bottom of the pump. You will need to remove the bottom paint cup to get the clog out. Remove the hose from the gun, remove the tip and then turn it upside down to drain any remaining paint in the system. Unscrew the bottom of your pump where you load your paint into it. There will be an access hole somewhere on the body of the sprayer that should have a screw-on cap over it.

Take the screw out and then you can remove the paint cup that fits in there, most likely with a screw off top. Remove the hose from your gun to the airline connector before removing this bottom cup. Let everything drain so all of the paint will come out of it. Check for any clogs in the area where the hose is connected to the bottom of the paint cup.

If you see any clogs, poke them out with a long tool or screwdriver and make sure they are all cleared out before reassembling them back together. Once everything looks like there is no more paint in there, it all back together again, and check to make sure the gun sprays. If it does, you may need a new paint cup or replacement hose as your original one might have been damaged from the clog.

Can you run paint thinner through a paint sprayer?

I need to remove some paint from my walls and was wondering if I could use a pressure sprayer with paint thinner or will it melt the sprayer?

I’m sorry we don’t have any experience with your particular sprayer. But I would suggest trying it in an inconspicuous area first, as some paint sprayers may be able to handle the thinner and some may not.

How to clean water-based paint from a spray gun?

First of all, I need to say that I am not a chemist and this is just my humble opinion. From what you say each paint should be water-based since you add water at the end. Spray paint contains organic resins which react with alkalis (soap) and form insoluble materials which clog up your spray gun and paint lines.

If you mix up a solution of water and regular dishwashing soap (not the kind for delicate hands) it should be possible to dissolve the leftover paint in the pot. 

Make sure your mixture isn’t too strong because otherwise your spray head might get blocked as well! After that add some freshwater to bring down the concentration of soap and/or paint particles. Now your gun should be clean!
