Paint and Bottom Maintenance

Paint is used on boats to protect its surfaces from wear and damage. Marine paint may be oil- or water-based, and is typically classified at topsides paint or bottom paint. Marine paints may be applied by owners or by boatyards, and they usually have specific instructions concerning surface preparation, application temperatures, and specific drying times. Bottom paints traditionally have included some form of copper additive to inhibit marine growth below the waterline, but these days, there are new biocides that work equally well. Bottom paints are formulated to wear away at specific rates, according to the speed of the cruiser and the waters where it is kept.
