FAQ’s

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.

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.
