Practical: 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. 
Remove rust scale, loose mill scale, loose rust and loose coatings by scraping and wire brushing to St 2 (ISO 8501-1: 1988), light blast cleaning or sanding. 
Sand previous coatings, which are in good condition to roughen the surface slightly. 
The surface must be clean and preferably dry during application.
