Removing dried latex paint from your paint sprayer is of crucial importance. As you can already guess, the spray equipment won’t work as it is designed to if it’s not properly cleaned.

Unfortunately, the paint typically builds up very quickly inside the sprayer and then dries in there. This can cause the bearing to become stuck. Moreover, the dye can also dry up in the model’s tip. As you already know, every sprayer’s tip has a small hole through which the dye is forced. In case it becomes clogged, the colorant will not be able to go through it at all.

Learn how to remove dried latex paint from your sprayer’s working components.

How to Do It

 

  • Start by removing the tip and the spray guard from the end of your gun. Typically, the tip slides inside a hold which is situated on the spray guard’s side. Carefully pull the tip out of the guard.

  • Take some warm water and clean the spray guard as thoroughly as you can. Something that can be of great assistance here is a soft bristle brush. Once you’ve washed the tip, try looking through the hole while holding it toward the light source. You should be able to see the light coming through it.

  • Carefully unscrew the gun’s top part from the handle. There’s a filter inside the handle -remove it from your gun and then rinse it with water as thoroughly as you can, i.e., until there’s no more dye on it. Reassemble the gun, but without the filter (this is only temporarily). In case you can’t get it apart, take a pair of channel locks or pliers to grip the handle and turn the top by hand.
  • Take the 5-gallon bucket that you’ve prepared and fill it with clean water. Put the siphon tube set (situated on the sprayer’s front) into the bucket. After that, turn on the sprayer in its prime position for a couple of moments.

Buckets with spilled paint
  • Turn the device to the “on” position once you allowed it to prime (or draw water) to the pump. After that, aim the model’s gun into your second bucket and spray into it until there’s no more paint in the hose and the sprayer itself.

  • Take a bucket and refill it with clean water. Then, turn your device back to its prime position and allow it to prime until the tube that’s attached to the siphon is completely clear, i.e., with no dye on it. Turn the device back to its “on” position, and spray water through its gun and hose until you notice that it’s spraying clean water.

  • On the end of the siphon hose is an inlet strainer -it looks like a screen, and you can remove it by turning it counterclockwise. Wash it with some water and carefully put it back in its place. Unscrew the gun’s top from the handle and finally put the filter back in its place.

  • Don’t forget to use throat seal liquid after each use. Its job is to protect the pump rod and the packing’s from becoming encrusted with dried paint, as well as from excessive wear.

This liquid is squeezed into a hole that’s located on the frontal part of the sprayer. The user manual that came together with your model should specify the precise amount of throat seal liquid you’ll need to use. Most models require between three and five drops after every use.

In case you’re using oil-based colorant, the cleaning process is quite similar to the one described above. You will, however, have to use paint thinner or mineral spirits instead of water.

Typically, it is not necessary to use a full bucket -you’ll need only the amount that will let you prime the system with thinner. This should keep the dye from getting dried inside the system.

Although it might seem complicated, cleaning dried latex paint from your equipment can be done quite quickly once you get the hang of it. And properly cleaning your sprayer after each use is of crucial importance -it’s something that gives your device a longer lifespan and improves the appearance of your finished projects.
