Tips to remove dried latex paint from paint sprayer

  • If the detergent method does not work, you can try using a paint stripper. This is a more aggressive method, so be sure to test it on a small area of the paint sprayer first to ensure that it does not damage the equipment.
  • With these tips, you should be able to clean your paint sprayer and get it ready for your next project.


Latex paint can be a pain to remove, but it is possible. You can use a heat gun to help soften the paint. You will have to work it a bit, and the longer you hold it the hotter it will get. Don’t hold it to close or you will melt the paint and ruin the finish on your furniture. The heat will cause the latex to become soft and easier to rub off. You can also use paint thinner. You will need to rub a lot harder as this will take some time.

Yes you can, but you should always run water through the paint sprayer first, because paint sprayer will clog as paint dries up in the components, and it will be hard to clean it. In addition, paint sprayer will lose its prime. If you want to clean the paint sprayer, you need to do it in a paint can, and soak it for about 24 hours. You should never run paint thinner through a sprayer because the thinner will destroy the sprayers.

Make sure you follow all the safety precautions that come with the paint gun. The first thing to do is flush the barrel with water while it is still hooked up to the air compressor. Then, you need to drain the water out of the barrel, but do not disconnect the gun from the air compressor. Next, you will take some solvent, pour it into the barrel, and spray it again. This step will clear any debris, paint, or hardener in the barrel. Finally, remove the barrel, clean it with solvent, and give it a light sanding to ensure that there are no paint particles left. Put the barrel back on the gun, reconnect it to the air compressor and spray some water through it. You should thoroughly clean the gun and both nozzles after every project.

You can use a hair dryer to heat the rubber and dissolve it, but it’s not easy to do that. You can use lighter to melt the latex because it is easy and safe to do it. Put the lighter into the hardened rubber and heat. Don’t heat it too much or too long. You can also use hot water with a drop of soap. You can put the latex in a cup of hot water and add a drop of soap. Mix them with a stick.

Dried liquid latex is a normally very simple substance to dissolve, but most people make mistakes when it comes to dissolving it. The most important thing is to not overdo things being too rough.  The best way to dissolve dried latex is using a neutralising powder in small amounts. You can dissolve it in a cup of very hot water, stir and keep the solution at room temperature, when the solution has cooled down, the latex will be dissolved. Another method is to use cold water, add ammonia and stir. After a few minutes, the latex will dissolve and you can flush it down the drain.
