Before application, all surfaces to be coated shall be assessed and prepared in accordance with ISO standards. Grease, if present, shall be removed by solvent cleaning to SSPC-SP1; blast clean to Sa2.5 or power-tool clean to St3, and remove dust and dirt. Use with a suitable heat-resistant primer; keep the primer surface clean and dry.
