Apply Thinner to Mix the Paint

Next, you need to pick good-quality paint that is oil-based. And latex-based or acrylic paints are also good for this purpose. As you can’t directly use the paint due to consistency, it’s time to add thinner or water.

For that, we suggest checking the instruction manual before adding anything. Ensure to make the paint in the right consistency before transferring it into a spray gun with a compressor.  

Turn On the Air Compressor

In this step, you need to strap the air compressor. And, it might need some time to build up pressure. Just revolve the controller of the air compressor to regulate the pressure of the spray gun. And then, be sure to adjust the pressure to apply the spray gun. 

Fix The Spray Pattern

After adjusting the pressure, you need to focus on the spray pattern of the paint gun. And most of the time, the spray gun will come in 3 patterns which are vertical, horizontal, and circular patterns.

  1. Vertical Pattern: Spread paint in straight up to down motion. Good for walls.
  2. Horizontal Pattern: Spray paint in left to right movement. Ideal for fences and railings.
  3. Circular Pattern: Spray gun flow painting in the round nozzle. Perfect for touch-ups.

Use The Air Paint Sprayer

Now, apply the spray gun using an air compressor. Be sure to hold it at least 7” to 12” far from the surface. And also, before pressing the trigger, it should be in the upright position to use on the targeted place.
