Step 4: Reassembling the Paint Sprayer

Once all the components are dry, reassemble the paint sprayer by attaching the hose to the pump, then attaching the paint container to the spray gun. Finally, attach the spray gun to the hose.

Tips for Preventing Dried Latex Paint in a Paint Sprayer

Prevention is the best way to avoid the hassle of cleaning dried latex paint from your paint sprayer. Here are some tips to prevent dried latex paint:

• Clean the paint sprayer after each use.
• Use the correct cleaning solution for the type of paint used
• If you need to take a break while painting, cover the paint container with a lid to prevent the paint from drying out.
• Use a strainer when pouring paint into the container to prevent any debris from entering the paint sprayer.

Troubleshooting Common Problems

Even with preventative measures, some issues may still arise with your paint sprayer. Here are some common problems and their solutions:

• Clogs in the spray gun: If you notice a clog in the spray gun, remove the nozzle and soak it in a cleaning solution for about 30 minutes. Then, scrub it with a cleaning brush and rinse it with water.
