This article describes the processes involved in preparation and painting of cargo tanks and ballast tanks in chemical tankers. Emphasis is placed on the timing and sequence of procedures such as sandblasting, grinding and vacuum cleaning of surfaces to be painted. Delays in beginning the painting can cause rust to set in and so require a second cleaning process. The article also emphasises the importance of high skill in spray painting. Skilled painters can judge very closely the coating thicknesses required. Ballast tanks, by virtue of all the stiffening members they incorporate, and their situation, are more difficult to clean, paint and then maintain free of rust than cargo centre-tanks. The only paints that have proved able to respond to these difficult constraints are coal-tar based paints with a high solid content. These can be applied in two coatings after surface irregularities have been patched over with diluted coal-tar epoxy paint. Order from BSRA as No. 52,257.
