Surface Preparation
| Substrate | Minimum | Recommended |
| Carbon Steel | Sa 2½ (ISO 8501-1) | |
| Stainless steel | The surface should be blasted with a non-metallic abrasive, | “Blast clean using an approved non-metallic abrasive |
| hand- or machine-sanded using abrasive paper or fibre discs, | to produce a sharp angular surface profile.” | |
to produce scratch marks on the surface.
| Galvanised steel | The surface should be clean, dry and have a suitable profile | Sweep blast with a non-metallic abrasive to produce a clean, |
| ° | a rough and uniform surface. | |
| Concrete | Dry abrasive blast clean to SSPC-SP 13 / NACE No. 6. | |
The recommended surface preparation provides optimum properties including adhesion, corrosion resistance, heat resistance and chemical resistance.
This product may be applied by the following methods
| Spray: | Apply by airless spray. |
