PRETREATMENT FOR PAINTING-PAINTING MAINTENANCE

This article examines aspects of correct pretreatment for painting and the building up of a ship's protection against corrosion, as well as maintenance during voyage and in other situations. The pretreatment and cleaning of the base surface before painting as carried out is seen as the most important factor in determining the lifespan of a paint system. Various pretreatment processes are described. The Swedish standard SIS 055900 is quoted as giving a good representation of the degree of surface purity required in various situations. Standards of pretreatment for different coatings are suggested. Some points regarding painting specification and maintenance are given. Most Norwegian shipyards use chlorinated rubber paint for exterior protection in ships, and a common specification on underwater hull surfaces is three coats of chlorinated-rubber based anti-rust primer (total minimum dry film thickness of 200 micron) followed by one coat of chlorinated-rubber based anti-fouling paint. The use of "wet docking" and TV-camera monitoring of underwater hull condition are described as means of maintaining hull protective coatings while reducing the need for dry dockings.
