Underwater epoxy
        
        A small number of two-part epoxy coatings have the unique feature of being able to be applied underwater. Common			applications include coating piers, pilings, pools, tanks, etc. In many areas			of the globe, humidity levels are often well above 75% nearly all of the time. With such high moisture levels,			most dry surface paints will have a much reduced surface bond which can result in premature blistering or coating			failure. Simply put, moisture, in whatever form, is a primary reason for coating problems. Underwater (i.e. wet			surface) epoxies avoid this area of concern. These epoxies can, of course, be used on dry surfaces much like any			other coating. Besides those already mentioned, other places you are likely to find underwater epoxies include			the inside and outside of ships, inside manholes, on cooling towers, piers and pilings, and tanks, pits and sumps			of all kinds, as well as on floors with vapor transmission problems.
