TREATMENT OF PAINTED SURFACES

摘要

A process for the removal from a hull of a ship of an outer leached layer of an antifouling paint which originally comprised a paint binder and a biocide but from which seawater-soluble material has been leached comprises applying to the surface of the antifouling paint a water-dispersible composition comprising a solvent for the paint binder remaining in the leached layer. The surface thus treated is subsequently washed with water to remove the said water-dispersible composition containing dissolved or emulsified material of the leached layer, thereby exposing a surface of underlying intact antifouling paint.
