When it comes to coatings, surface preparation and surface cleanliness are the foundation, and both can significantly impact the performance of the coating system.Īpplication of a coating over dust will prevent it from adhering to either the substrate or the previous coat. As the old adage goes, a house is only as strong as the foundation it is built on. Either the surface preparation was inadequate, the surface was contaminated, or the coating was mixed or applied incorrectly. When a coating system fails prematurely, it is rarely because of the coating itself.
