Water-based Hydrocoat SR protects against hard and soft growth and cleans up easily with soap and water.Hydrocoat SR takes the proven formula of Hydrocoat and adds the slime inhibitor Irgarol for effective prevention of tough hard and soft growth. Easier on the environment, the water-based formula of Hydrocoat SR eliminates the offensive solvents found in most bottom paints, for easy application and cleanup, with low VOCs and no heavy solvent smell. Hydrocoat SRs surface wears away with use, which exposes fresh biocides and eliminates paint buildup along with the need for heavy sanding at haulout. Able to withstand trailering, beaching, and launching, the formula also allows unlimited dry time before launch—so you can paint when you want and launch when you please.Key Features Proven antifouling performance with added slime inhibitor IrgarolWater-based formula is safer for the environmentLow VOCs and no heavy solvent smellAblative formula eliminates paint buildup and reduces need for sanding at hauloutDoes not lose antifouling effectiveness when exposed to airGet the right amount of paint: Boat Type Bottom Paint 10' Dinghy 1 qt. 14' Outboard 1-2 qt. 18' Runabout 2 qt. 20' Sailboat 3 qt. 24' Runabout 3-4 qt. 30' Sailboat 1.5 gal. 32' Cruiser 1.5-2 gal. 36' Auxiliary 2 gal. 40' Cruiser 2.5 gal. 45' Sailboat 3-3.5 gal 50' Sportfisher 4+ gal. Note: The recommendations above are for two coats of paint. All values are approximate.Another way to determine bottom paint quantity is to estimate the approximate surface area of the hull below the waterline, using the following formula:Length x Beam x .75 = Approximate underwater surface area in square feet.Each paint has a theoretical coverage” area, but
