Abstract
A coating for ship hulls is designed for application to areas of the hull t accessible when ship is in dry dock. The means for applying the coating may take several forms: (1) a multilayered tape system having impregnated in or carrying an antifoulant and having a water soluble intermediate layer; (2) a sponge like layer containing impregnated antifoulant paint or coating liquid which can be squeezed therefrom onto the hull; (3) a sponge having mixed therein microspheres of resin and pigment and microspheres of activator material such that when the microspheres are crushed, the pigmented resin, which may also contain an antifoulant, and the activator are mixed and cured to form a coating on the hull. The preferred means and method for applying the coating, is to mount the tape system on the dock blocks in a dry dock before the dry dock is flooded to admit the ship, and by the settling then activate the coating the ship onto the blocks as the water is withdrawn from the dry dock. The coating may be applied by hand to small areas of damaged coating of the ship hull.
