How to Use a Paint Sprayer with an Air Compressor

Painting a surface with a paintbrush or roller is time-consuming and requires a lot of effort, especially if the surface area is vast. Fortunately, air compressors and paint sprayers can make the task a lot easier and quicker. Paint sprayers and air compressors work together to offer efficient and precise painting capabilities.

In this blog, we will be discussing how to use a paint sprayer with an air compressor, various spraying techniques, and maintenance tips to ensure that your sprayer lasts a long time.

1. Select the Paint Sprayer and Compressor

Choosing the right paint sprayer and air compressor is crucial for achieving perfect finishes and precise patterns. The compressor should have at least 7 CFM (cubic feet per minute) at 25 to 30 PSI (pounds per square inch) to use with the paint sprayer. Also, ensure that the nozzle size of the sprayer is compatible with the compressor’s capacity.

2. Prepare the Surface

Before painting the surface, ensure that the surface is thoroughly cleaned and free from dirt, dust, and debris. Sand any dents, holes, or bumps and ensure the surface is flat and clean. Masking tape or newspaper can be used to cover surrounding areas that are not meant for painting.

3. Fill the Paint Sprayer

Fill the paint sprayer with the appropriate paint or stain. Ensure that the paint is compatible with the sprayer’s nozzle size and type. Paint can be thinned according to the product instructions using water or a recommended thinner.

4. Adjust the Spray Pattern

Paint sprayers come with three spray patterns, which are horizontal, vertical, and circular. The pattern can be adjusted by rotating the nozzle collar. The spray volume can also be adjusted by turning the adjustment knob located on the sprayer handle.

5. Begin Painting

Ensure that the air compressor is turned on and adjust the pressure to the desired volume. Start by testing the sprayer on a small hidden area to ensure that the spray pattern is correct. The sprayer should be held at a distance of 6-8 inches from the surface and moved in a steady back and forth motion, ensuring that the spray pattern overlaps slightly. Once the first layer dries, another layer can be applied to get the desired thickness and finish.


Using an air compressor with a paint sprayer makes painting much more efficient and precise. Selecting the right sprayer and compressor, preparing the surface, filling the sprayer, adjusting the spray pattern, and beginning painting are the fundamental steps for efficient and effective painting. Always ensure to clean the sprayer and compressor promptly and store them safely.
