To expect long period maintenance of protecting steel surface, inorganic zinc silicate coating will become to increase a chance of its application especially to outer hull surface of VLCC and inner tank surface of products carrier. This experiment has an intention of finding suitable application method under the condition of keeping our present application system as much as possible. Model blocks and tanks are adopted as a test substance in the meaning of simulation of actual ship. Surface preparation is made with classified methods and paint coatings of scheduled systems and performance test of each coating film has been carried out for about one year. From the result of this experiment, we clarified the following item. (1) effect of shop primer coating and necessary grade of blasting in secondary preparation. (2) important factors giving influence on film crack. (3) effect of painting interval of overcoating on interlayer adhesion. (4) workability of slurry airless spray equipment developped for painting of inorganic zinc coating. (5) degree of contamination of products in contact with inorganic zinc coating. (6) anticorrosive performance of inorganic zinc coating for immersion into sea water.
