We offer on site electrostatic painting services on metal surfaces that require a finish that is very resistant to scuffing and scratching. Paints that are able to sprayed electrostatically and be true to the process are oil based and range in shine from semi-gloss to high gloss. These industrial oil based products are specifically tailored to offer extreme hardness and good shine however lack in the flexibility sector and are thus used for very specific applications. The process controls the amount of paint "fumes" emitted into the air by creating an electromagnetic current to attract the paint to the grounded surface (a surface that can conduct electricity only).
Electrostatic spray painting is extremely efficient when painting metal railings and fences on site as the paint wraps around the metal bars creating an even paint film all around while significantly reducing paint fumes. The process is also extremely efficient for high traffic interior applications such as doors, bathroom stalls, metal furniture etc.
Can you paint exterior aluminum siding using the electrostatic painting method? The answer is yes however it is not the best way to do so. Electrostatic painting is used to reduce the amount of paint fumes into the air by electro-statically charging paints and spraying them towards a conductive metal. Although most people see why this cannot be done for stucco, vinyl or PVC, most people don't see why we do not use this application method for aluminum painting.
The reason is that the best paints for aluminum siding are water based paints, due to their acrylic binder, which makes them much more flexible. In order to get any real benefit from electrostatic painting you would have to use paints that are more conductive and this not only greatly increases the cost, these products are highly toxic and are not best suited for aluminum siding but rather for high traffic commercial metals.
If it is paint fumes you are worried about, the air assisted technologies we use have similar transfer efficiency to electrostatic painting when using acrylic water based paints. You don't need to worry about paint fumes; we do not use cheaper airless paint sprayers when painting your home exterior.
