Proper surface preparation is essential for the success of any marine coating scheme. The importance of removing oil, grease, old coatings and surface contaminants (such as millscale and rust on steel, and zinc salts on zinc containing primers or galvanised surfaces) cannot be over emphasised. | .International. Marine Coatings Marine Paint Guide Updated 12 10 04 2. Surface Preparation INTRODUCTION Proper surface preparation is essential for the success of any marine coating scheme. The importance of removing oil grease old coatings and surface contaminants such as millscale and rust on steel and zinc salts on zinc containing primers or galvanised surfaces cannot be over emphasised. The performance of any paint coating is directly dependent upon the correct and thorough preparation of the surface prior to coating. The most expensive and technologically advanced coating system will fail if the surface preparation is incorrect or incomplete. STEEL Some of the various methods of surface preparation of steel are briefly described below. For more explicit details and recommendations please refer to full specifications such as 1.
