Damage to paint on a paint spray system

The results of

application of paint

is not only dependent on the quality of paint used and the preparation of the surface to be painted, but also a tool used to apply it. We can paint using a brush, roller or spray system.
paint spray Cratering, is one of the damaged painting is characterized by the occurrence of small craters on the surface of the paint layer is spread evenly on the affected area.
The cause:
  • The presence of contaminants such as oil, grease, water on the surface underneath.
  • Splashing water from the spray booth.
  • Water and oil from the air hose to spray gun.
  • Effect of dust spray (spray dust) are not yet dry on the paint that comes from another cat from spraying before or after.
  • Contamination of the paint itself.
  • Orange skin (Orange peel).

Orange peel, the surface layer of paint is not flat and bumpy like an orange peel.
The cause:
  • Spray viscosity is too high.
  • The volume of paint that comes out of a syringe (spray gun) is too large.
  • Distance of a syringe into the painted surfaces are too close.
    Spraying air pressure is too high.
  • Sticking Power Not Good (peeling).
On the surface layers of paint there are patches that are not uniform (for metallic paint) or there is a darker-colored areas and irregular (for paint).
The cause:
  • Spray viscosity is too high causing the thinner layer is too wet.
  • Thinner is too slow to evaporate.
  • Automated pressure is too low.
  • Pattern out of the paint spray equipment is too narrow.
  • Speed paint out of spray too tinngi.
  • Paint layer is too thick and uneven.
  • Spray too close to the surface to be sprayed.
  • Melt (Sagging / running).
Melt the paint so the paint is not flat and in certain parts of the paint is very thick. It is located on a vertical or angled surfaces.
The cause:
  • Too much thinner which evaporates slowly.
  • Paint layer is too thick.
  • Paint sprayed too often without sufficient waiting time between the coating with the next one.
  • Spray too close to the sprayed surface.
  • Low air pressure.
  • Discharge from the spray too much.
  • Paint spraying viscosity is too low.
    Dry spray.
