Painting your exterior walls is a job that you can complete much quicker if you use a pneumatic paint gun. Whether you buy or rent a paint gun, it is much quicker than trying to paint such a large area with rollers and brushes. However, using a paint gun does require special maintenance of the system. If you do not keep it as clean as possible, it will not work. This article explains some everyday maintenance and cleaning tips to practice while painting your home with a pneumatic paint gun.
Cleaning at the End of the Day
At the end of the day, when you are done painting, you need to properly clean and store your gun. First, you need to clear out the hose lines of all paint. The key is to have a 5-gallon bucket of water. Remove the intake hose from the paint bucket and place it into the bucket of water. Then, spray the gun for a minute or so (it might take longer) until water, and no paint, is coming out. You might need to spray into a large scrap of wood or cardboard. If your gun system has a longer hose, it will take longer for the paint to clear out of the lines, so you might need quite a large scrap.
Then, remove the gun from the hose. Take the nozzle out of the spray tip and clean it with some watered down paint thinner. Leave the nozzle out the gun and let it dry overnight. Place the lid on your bucket of paint and unplug your gun system, but leave the intake hose immersed in the water bucket overnight. The next day it will only take a few minutes to set up the gun and start painting.
Keeping the Gun Clean Throughout the Day
Throughout the days of painting you will obviously need to take a lot of breaks. Whenever you are not going to be painting for more than 30 minutes (maybe sooner on a hot, sunny day) you should place the gun in a bucket of water. This just prevents the paint in the gun nozzle from drying up and ruining the paint stream. When you pick the gun up to spray after a short break, spray a short burst onto a scrap of cardboard to remove any water that may have seeped into the nozzle.
