Abstract: The steel cutback surfaces were prepared by different methods to obtain the grade Sa25， grade St3 and have different salinity and roughness. Then the epoxy anticorrosive coatings and 2-HSS or 3-HSS were applied on these surfaces. The effect of surface preparation on the coating performance was investigated. The results showed that the surface preparation had a significant effect on the coating performance while the cathodic disbondment test rather than the peeling strength test was a significant way to reveal the effect of surface preparation on the anticorrosive property of the coating. However.
