Mar pro paint6/28/2023 Once a few seasons of paint have built up, a vigorous sanding prep is required to keep the hull smooth and clean. Long after theyve lost their antifouling properties, hard paints leave behind binding resins and pigments. The two types of paints work differently, but for our purposes, the most important distinction is the maintenance regimen for each. (See “How We Tested,” below.) The results are indicated in two tables (see pages 8 and 9), which are split between hard and ablative paints. This article focuses on the results of paint panels that were submerged in June 2008. In recent years, weve seen very good results in paints with relatively low percentages of copper, the most expensive raw material. While a drop in demand tied to the global recession might prompt special offers this spring, the only long-term price breaks were likely to see are through reformulated or new blends that try to make more effective use of less biocide. The formula changes seem most prevalent in the low-budget paints, as manufacturers try to meet a price point and still deliver a product that boaters can rely on. The formulas of several familiar antifouling paints were adjusted in recent years, and we expect more modifications as manufacturers grapple with the rising cost of raw materials and increased pressure from regulatory agencies to minimize the environmental impact of the paints. Bottom paint prices continue to rise, pushing the $300-per-gallon mark, and the expenses associated with bottom fouling can quickly eat into a maintenance budget.Īnother key reason to pay attention is that the technology-as well as the market-is rapidly changing. Practical Sailor spends a lot of time studying bottom paint for good reason.
