Answer: High solids or emulsions formulas are very difficult to atomize with just 10 psi of air pressure from an HVLP gun. … These coatings were designed for spraying with airless equipment or conventional air spray guns (coating reduced) for small jobs.
What causes orange peel with HVLP?
Orange peel is the most universal defect in a sprayed finish. … The most common cause of orange peel is an imbalance between the viscosity of the finish and the amount of air atomizing the liquid as it exits the gun. The thicker the liquid, the more air that is required; the thinner, the less air needed.
Why am I getting orange peel when spraying?
Orange peel is typically the result of improper painting technique, and is caused by the quick evaporation of thinner, incorrect spray gun setup (e.g., low air pressure or incorrect nozzle), spraying the paint at an angle other than perpendicular, or applying excessive paint.
Can too much air pressure cause orange peel?
When spraying any material through a pressure pot, even with the proper viscosity material, tip size and air cap, you can still get the dreaded orange peel effect. … On the other hand, if you drive the fluid pressure too high, the material will come out too heavily, resulting in over-application of the coating.
Can you polish orange peel out?
When it comes to paint, one way or another there always is. Yes, orange peel is fixable. My challenge to you is to question at what cost. In my opinion it’s much easier and more effective to polish the area and smooth out as much as you can without being too abrasive, then follow with a nano coating.
How does HVLP prevent orange peel?
