How To Clean A Graco Paint Sprayer With Dried Paint

Once you have all the necessary materials, you can begin cleaning your Graco paint sprayer with dried paint.

Gather the required materials:

Ensure you have the above items before cleaning your Graco paint sprayer with dried paint. This includes a coverall/paint suit and gloves for protection, eye goggles for safety, a drop cloth/rag to protect your working surface area, a garden hose or pipe to connect the unit to a water supply, buckets for collecting rinsed water, and dried paint residue, a soft-bristled cleaning brush and pliers to remove stubborn pieces of dried paint from the cap and nozzle area of the sprayer, mineral spirits as an alternative cleaner instead of using water only in some instances, and a cleaning cloth.

Disconnect Hoses & Remove Plug:

Begin by disconnecting the garden hose from the Graco paint sprayer and gently pulling the Plug from its connection port.

Rinse Unit:

Using a water supply, rinse off the unit’s exterior to remove any debris or dried paint collected on it. Be sure to use gentle strokes for effective cleaning, and don’t apply too much pressure when scrubbing with the soft-bristled brush.

Clean Cap & Nozzle Area:

Using pliers, carefully remove any bits of hardened dried paint from around the cap and nozzle area of the sprayer. Ensure you are gentle while doing this, as too much force can damage these areas. Once removed, clean any remaining residue using mineral spirits or a cloth soaked in warm soapy water.

Rinse the Unit Again:

Once all the dried paint has been removed from the cap and nozzle area, reattach the garden hose and rinse off the unit once more for a thorough clean. This will also help to remove any mineral spirits or soapy residue that may still be present on your Graco paint sprayer.

Dry & Reassemble:

Allow your Graco paint sprayer to air dry before reassembling and storing it properly. Ensure no water is left inside the unit, which can cause rusting or other damage over time.

Test Spray:

Before using your Graco paint sprayer again, it’s a good idea to test spray on a piece of scrap material first. This will help you ensure that the unit is in complete working order and that all dried paint has been removed from its interior components.

Following these steps, you can effectively clean your Graco paint sprayer with dried paint and get it back into top shape for future projects. Use safety precautions when handling cleaning chemicals, and do not damage unit parts. Properly maintained and cared for, your Graco paint sprayer should last you many years!
