What is overspray
Written by: Vinnie van Rooij
Overspray is caused by the mist that is created when spray painting a surface. The tiny paint particles are light enough to float around in the air, when they land they slowly start to harden and become overspray. Overspray can be removed safely in many cases.

Why overspray
When a painter needs to spraypaint a surface, he needs to set his equipment to work with the paint he is using. The paint is pressed through a nozzle that atomises the liquid paint into a very fine mist of tiny paint drops. This very fine mist is then sprayed on the surface to form a very even layer of paint drops. These slowly harden into a coat of paintwork. The very fine mist of paint is very light and is easily carried by air. This mist can float to area that are not covered by masking tape, and settle on a surface they are not supposed to come into contact with.
