Abstract
The present invention relates to a method for the establishment of a crack resistant epoxy paint coat and paint compositions suitable for said method. The method is developed for use in ballast tanks e.g. a ballast tank of a vessel. The method involves the steps: (i) applying a paint composition comprising an epoxy-based binder system onto the surface thereby forming a curable paint film on the surface, and (ii) allowing the curable paint film to cure thereby forming the epoxy paint coat. The paint composition has a viscosity of at the most 140 KU, when ready to be applied. The paint composition comprises 35-80% by solids volume of the paint of an epoxy-based binder system having a ratio between the hydrogen equivalents and the epoxy equivalents in the range of 20:100 to 120:100. The paint composition furthermore comprises 0.5-30% by solids volume of the paint of one or more fibers. The fibers have an average length, of at the most 250 μm.
