Different spray guns use different pressures for liquid and air, and therefore the distance of painting is dependent on the kind of spray gun you're using.

An HVLP spray gun requires that you be at least six to eight inches from the surface you paint. Keep 8-10 inches away of distance from your surface with a traditional spray gun.

Air-assisted airless sprayers are utilized 10 to 12 inches away from the chosen surface. Airless sprayers have high pressure and can be utilized anywhere between 12-14 inches.

6. Its time to start painting:

Do not spray directly on the surface while trying to coat it. It is best to begin streaming to the side of the surface and then move your arm toward the desired consistency.

Also, don't stop gliding or spraying at the edges of your surface. Instead, apply the spray further than the edge to avoid too excessive build-up of paint. To ensure an even spray over the entire surface, you should move your arms in straight lines.

Paint that is thin coats is superior to thick ones. Therefore it is recommended to apply only one coat at a time and then let it dry. Drying times typically range from 30 to 45 minutes.

Every manufacturer has some specific instructions for cleaning, that you must adhere, to achieve the most effective outcomes. Regularly cleaning ensures that the sprayer is applying an evenly coated paint layer.
