ABSTRACT:
An epoxy coating composition, a coating and a method of applying the coating composition to items to be used or being used in marine environments and otherwise susceptible to the deleterious effects of erosion and/or corrosion. The coating composition is comprised of a polyamine converter and an epoxy resin that can be applied either to virgin metal or to preexisting metallic items immersed below sea level. The coating in either situation is comprised of a plurality of layers of the epoxy composition sequentially applied about the affected surface area of the item with a wrap of vitrified cloth disposed intervening between juxtaposed of said layers. Where on site restoration of an item is to be performed, some or all of the layer applications can be conducted underwater by preceding application of the coating with an abrasive blasting of the surface to be coated.
