By preparing the surface, contaminants that interfere with adhesion (grout, dirt, oil, paint, etc.) are removed and the surface profiles required for the specified coating are established
Abrasive blasting is the most widely used cleaning method as it provides fast, cost-effective cleaning and creates a rough surface suitable for good adhesion of most coating systems.
Surface profile measurement using replica tape is performed after surface cleaning to ensure that the prepared surface has the required profile as indicated in the coating specification.
Approximately 70% of paint failures are caused by inadequate surface preparation. No matter how good the coating is, it will not perform to its fullest capacity on a poorly prepared surface.
In industry, there are constantly situations where a high durability of the coating protection scheme is required and a white metal grade surface preparation is demanded, without the use of abrasive blasting being allowed.
