Painting has come a long way from simply using a paintbrush and smearing paint all over a primed surface. New ways of putting pigments on surfaces have become more favored in the industrial world due to their marked efficiency and speed. One of these techniques is electrostatic painting – a process by which the adhesive quality of the paint is completely replaced with a different force of attraction that happens at the electrostatic level.
Things You'll Need
- Metal Surface To Be Painted
- Dry Powder
- Gas Mask
- Spray Gun With Customizable Amperage
- Safety Shoes
- Curing Ovens
- Finishing Coating
- Safety Gloves
Put on the necessary safety equipment.

Prepare the metal surface to be painted. This step is crucial since any imperfections in the surface could compromise the paint job. Go through the protocol of polishing the surface and filing down the rough imperfections that may become trouble areas during the application of the resin. The metal should also be free from any other material like grease or water. Make sure that the surface is dry as a bone.
Prepare the dry powder. The powder used for electrostatic painting is usually put into a supply reservoir to charge them a certain way. They are then fed into a spray gun whose amperage could be modified according to the requirements of the paint job. This setting would then be used to determine the amount of grounding to be used on the metal surface to be painted.
Blast the surface to be painted with the spray gun. If you have properly calibrated the charge on the dry powder with the grounding of the metal surface, the powder should stick to the metal right away. The technology takes advantage of the very strong atomic forces that keeps oppositely charged bodies together – similar to how dust always accumulates on your computer monitor due to the negative charge of the screen.
Apply a finishing coat on top of the pigments to ensure that the bond between the metal and the paint remains after the charge and grounding have dissipated.
Put it in a curing oven. The oven should be setup in such a way that the finishing coating is activated to seal the metal surface and permanently bond the dry powder to the surface.
