– Equipment efficiency restored
Proper surface preparation is essentialfor the long-term performance of the coating. The exact requirements for preparation vary depending on the severity of the application, the expected service life, and the initial condition of the substrate.
Prior sanding and grinding of edges and welds
All sharp edges and welds must be ground with an abrasive disc until smooth or with a 3 mm radius to prevent premature failures.
Cleaning and degreasing
Remove contaminants to improve coating adhesion.
Abrasive blasting
Achieve white or near-white finish (SSPC-SP10) with an angular profile between 75–125 µm.
Removal of residues
Carefully remove abrasive residues that may interfere with the application.
