Surface Preparation
The steel surface to be coated must be thoroughly cleaned of oil, scale, rust, and old coatings. This can be achieved through blast cleaning methods such as shot blasting or sandblasting, meeting the Swedish Standard Sa2.5, with a surface roughness of 30–70 μm. Alternatively, manual cleaning methods can be used to meet the Swedish Standard St3, with a surface roughness of 30–70 μm.
Safety Measures
