Application conditions
The substrate temperature shall be at least 3 °C above the air dew point, and the relative humidity below 85%. Temperature and humidity shall be measured on the substrate close to the work area. When applying in enclosed spaces, good ventilation is required to ensure normal drying of the film.
Surface Preparation
The performance of the coating depends on the quality grade of surface preparation;
| Bare steel | Blast clean to Sa2 or Sa2½ of ISO 8501-1, with the blasted surface profile recommended to be 40–80 µm; high-pressure water jetting to WJ2/3L of SSPC VIS 4; disc grinding to St3; |
|---|---|
| Shop-primed steel | Light sweep blasting, or abrading rusted areas with a flexible disc to St3; |
| Areas burned by welding, flame cutting or fairing | Remove weld slag and spatter, grind smooth, then abrade with a flexible disc to St3; |
| Confirmed compatible previous coats | The surface shall be clean and dry, with all contamination removed; |
| Galvanized | Remove zinc salts; sweep blast or otherwise clean and roughen the surface; |
| Stainless steel / aluminium | Degrease, remove contaminants, roughen the surface; |
| FRP | Remove surface contaminants and abrade the surface; |
Remove mortar laitance at the edges.
