Definition - What does Spatter Coating mean?
A spatter coating is a protective layer that is blotchy and not uniform. It is a defect that typically occurs due to operator error or an equipment malfunction as the coating is sprayed onto the intended surface. A spatter coating may reduce the effectiveness of corrosion prevention efforts.
Corrosionpedia explains Spatter Coating
A spatter coating can occur due to a variety of factors. Some spatter coatings are caused by faulty equipment. For example, if the spray gun is not working properly, then an inconsistent coating may result.
A spatter coating may also be created if the coating liquid is mixed to an incorrect viscosity. If the coating is too viscous it may not come out of the spray gun properly.
Improperly trained personnel or poor technique are other causes of spatter coatings.
