1  Surface preliminary treatment 

All foreign matter with harmful affect to preliminary treatment and painting is to be 
removed. All water based salts are to be removed with a dirt- and grease-removing 
agent according to SFS-EN ISO 12944. The surfaces are pre treated according to 
material, as follows: 

Steel surfaces: Mill scale and corrosion is removed by blasting to tolerance Sa2½ 
(SFS-ISO 8501-1). The roughening of sheet metal increases the paint bonding to the 
surface.
