PRACTICAL CONSUMPTION
Practical coverage depends on many factors such as porosity and roughness of the substrate
and material losses during application.

SURFACE PREPARATION
Remove grease, oil and all other surface contaminations by alkaline- or high pressure (steam)
cleaning in combination with appropriate detergents. For optimum results remove rust, rust
scale, mill scale and deteriorated coatings by abrasive blasting to Sa 2½ (ISO 8501-1 : 1988),
blast profile max. 50 m. The surface must be clean and dry during application.

DIRECTIONS FOR USE
To ensure homogeneity, coating materials should be thoroughly stirred prior to use.

APPLICATION CONDITIONS
Temperature of air, substrate and coating material between 5 and 35°C and relative
humidity below 85%. The substrate temperature must be at least 3°C above dew point.
