A coating is a material that is applied to the surface of a substrate to improve its performance. Surface preparation plays a vital role in ensuring performance. The objective of surface preparation is to facilitate the adhesion of the coating, the level of adhesion of which determines whether the coating is just a thin film lying on the surface, or if it is able to offer effective protection by becoming part of the substrate. If the surface is not properly prepared, the coating cannot be applied correctly, which will only cost more time and money down the track once the equipment fails.
