Protective coatings and antifouling paint that can be applied underwater are being studied experimentally both in laboratory and field tests by the U.S. Navy Civil Engineering Laboratory. Protective coatings and antifouling paints applied by brush, roller, or plastic applicator to underwater surfaces can protect from corrosion and marine fouling for at least 1.5 yr. Study of five methods of surface preparation showed that sandblasting is best, but that power wirebrushing or water blasting can be satisfactory. As little as 0.9% tin (as tributyltin) in the coating reduced fouling noticeably; however, 6% tin was required to compare favorably with the standard Navy copper-based antifouling paint used for comparison purposes. The new formulations can be used to repair damaged coatings or restore fouling resistance on waterfront and offshore structures and on hulls of ships without their removal or drydocking, thus saving time and money.
