Recently, there has been an increasing tendency to use tar epoxy resin paint as coating material of vessels. This paint, however, has the shortcomings in its adhesive property diminishing between the first coat of the paint film and the second one unless adequate painting intervals are taken. This study has been conducted to look into the relations between the adhesive property of the said paint and the environmental conditions in the shipyard. As a result, it has been concluded that the following factors are responsible for the lessening of the adhesive property of paint. (1) The greatest factors affecting the adhesive properties are the weathering of the first coat by ultra-violet rays and adhesion of oil. (2) Adhesion of oil to the first coat of the paint film worsens the wetness of the second coat of the paint film. To prevent the adhesive incongruity, it is neccssary to make a surface preparation in such a manner as to "peel off" the surface of the first coat of the paint film with a grinder or a power brush.
