In doing a painting job under the conditions of closed spaces like the inside of box girders, the measures preventing the explosion of solvents, which may be volatilized from paints, should be taked. For the purpose of developing non-solvent type paints, painting tests inside of box girders were carried out about 20 years ago. As it is very important to evaluate the deteriorated paint films for the maintenance of box giders, their states were investigated. From these results, it is found that they do not much change from the initial state after the test painting. Therefore, it can be judged that they possess excellent durability under above conditions of no ultraviolet irradiation.
