On-site electrostatic painting refinishing involves the complete cleaning, resurfacing, and re-coating of items that are at or near where they are used. Electrostatic Painting is usually done in carpeted offices or other places where overspray and contamination must be kept to a minimum. The primary concern is that crew-members or operators do their work in a tidy manner.

Electrostatic Precision Painting uses 2 basic steps: cleaning or prepping of the surface for painting, and the actual painting process. Everything on the outside of the object being painted is cleared, but it is not necessary to empty out interiors.

Using a grounding wire and clamp, the objects to be coated are grounded to the nearest available earth ground. This could be any metal portion of the structure of the building.

As with any electrostatic painting, the surface of whatever is being painted needs to be clean of all debris, to ensure the adhesion of the film coat, and the look of the final finish. This also includes rust, scale, and peeling paint. This can usually be done with wet or dry sandpaper.

Any gloss from the original paint should be removed to ensure that the new coat adheres properly. Once the electrostatic painter is sure the surfaces are properly prepared, he must mask what he does not want painted (i.e. drawer handles, desk tops).
