Overspray (paint mist)

When painting surfaces, paint mist (overspray) may occur during the spraying process. This mist consists of fine paint particles that do not hit the object to be painted directly, but float in the air and can settle on surrounding surfaces.

The overspray phenomenon can have various causes, including the use of sprayers with too high a pressure setting, inaccurate alignment of the spraying device or the use of paints with too low a viscosity. Controlling overspray is important to ensure an even finish and avoid unnecessary paint loss. Various techniques are used in painting technology to minimize the overspray problem. These include the use of paint booths in which air circulation is controlled and the adaptation of sprayers to minimize paint mist. Covers and masking are also used to protect neighboring surfaces from unwanted paint application.

Controlling overspray not only contributes to the efficient use of paint materials, but also prevents contamination of areas that are not to be painted. In industrial applications, such as automotive production or furniture manufacturing, precise control of the spraying process and minimization of overspray is of great importance to ensure high-quality end products.
