How to Set Up an Airless Paint Sprayer

Did you just buy an airless paint sprayer from for your food shelves and cabinets? Don’t worry; we’ll teach you how to set it up today.

Step #1: Cleaning the sprayer’s screen

art-paint-painting-bucketAll airless paint sprayers come with a screen located at the intake. Clean this first. A lot of sprayers also include two removable filters—one placed close to the pump and the other’s in the gun’s handle. Also make sure both are clean. Next, filter your paint using a mesh strainer bag to get rid of the lumps in the paint to prevent them from clogging the filters.

Step #2: Priming the pump

In a waste bucket, place the prime tube. And in a pail of strained paint, place the prime tube. Switch the spray valve to prime. Turn the pump on, then rotate the pressure valve till the pump begins to run. Once the paint starts flowing from the pail to the prime tube, transfer it into the paint bucket.

Step #3: Filling the hose

Remove the guard and the spray tip of your spray gun. Hold it over the waste pail, then pull the trigger. Now turn the valve from “prime” to “spray.” Release the trigger once you notice that the paint is running in a stable flow from the spray gun. Lock the trigger and turn the sprayer off. Switch the valve from “spray” to “prime.” Target your spray gun against one side of your waste bucket, then pull the trigger to let out the pressure. Engage the lock of the trigger.

Step #4: Adjusting the pressure

Switch the pump on and change the valve setting from “prime” to “spray.” Before spraying on the final workpiece, test spray on a scrapboard first to examine the pattern of the spray. If the pattern seems to have tails, you need to turn the pressure up. Remember that a pressure set too low will create an irregular pattern. Excessively high pressure, on the other hand, will result in overspray and make the spray tip wear off earlier than it should. If in case you still see tails even if you’ve chosen the maximum pressure already, then use a spray tip with a much smaller hole. If you observe that the pattern isn’t narrow, and instead it’s round, that means you should replace the tip as it has already worn out.

Step #5: Painting

Start painting by pulling the trigger. Move it across the workpiece. Make sure it’s always parallel to the surface. Don’t move the gun in an arc and don’t tilt the gun. To avoid runs, you must move quickly. Remember that a number of thin coats will appear better than a single thick layer. Always overlap your paint strokes about 30-50%.
