Many of our subscribers have this common question.
What causes orange peel and how to I get rid of orange peel on my paint job?
This can be a tricky subject because there can be many causes for orange peel in your paint job. Below I will explain what I think the most common mistakes and problems are, and also possible solutions that you may use to eliminate and reduce orange peel on your paint projects.
1st. The most common mistake is the wrong paint viscosity of paint material.
When you’re mixing paints and add more activator or hardener than needed into your clear coat you may kind of mess yourself up because the clear coat won’t actually have the time needed to flow out properly.
After painting, you’ll notice it hardens with an orange peel effect (see pictures) It also depends on the reducer temperature that you’re using. A reducer that dries too fast in hot weather may also cause orange peel, again because of improper flow of material.
2. Low Pressure Spraying. When spraying a job with insufficient air pressure you will not give your paint a chance to atomize and break up enough to flow out nicely on your panel.
Atomization: Here is the definition for ‘atomize’ below.
verb [ trans. ]
convert (a substance) into very fine particles or droplets : the CO 2 depressurized, atomizing the paint into a mist of even-size particles.
• reduce (something) to atoms or other small distinct units : by disrupting our ties with our neighbors, crime atomizes society.
atomization |ˌatəməˈzā sh ən| noun
When spraying a job with insufficient air pressure you will not give your paint a chance to atomize and break up enough to flow out nicely on your panel. Your Solution: Spray using a HVLP spray gun if you have one and use at least 28-30 psi when spraying your paints.
3. Speed and flow of spray gun. You need to make sure that you have proper spraying patterns and even flow with your gun using the 50% spray pattern overlay.

4. Needle size. Some people make the mistake of painting with a 1.8 nozzle rather than the 1.3-1.4 that’s recommended when painting automotive finishes. Make sure you use the standard 1.3-1.4 nozzle tips when painting with automotive finishes.
5. Ambiant Temperatures. Hot weather painting can cure your paint faster than you want it to. Use a slow reducer and activator when painting in hot temperatures.
