This dual biocide product uses both copper and Irgarol to produce a most effective thin film antifouling. SR-21 is designed for fresh water usage. This no-drag coating is easy to apply and dries in 15 minutes, ready to launch- instantly. Using a patented "solid lubricant" , fast was never this simple. Colors change after immersion.

SR-21 Antifouling Paint forms an ultra-thin low friction film for boat bottoms. It is the ideal racing finish for fresh water or cold saltwater boats. SR-21 contains copper powder as well as a slime reducing biocide to prevent the attachment of fouling organisms such as barnacles, bryozoa, toredos, zebra mussels and algae.
SR-21 contains two slicking agents PTFE (polytetrafluoroethylene) and Molybdenum Disulfide which reduce surface friction allowing the hull to slide through the water. SR-21 is recommended for use on fiberglass, wood and properly primed steel boats.
Mix all of the copper powder into the liquid portion stirring thoroughly to ensure the copper powder is evenly dispersed in the liquid. Stir occasionally during application. Apply SR-21 with a short nap (no more than 3/16 inch nap) or foam roller. Roll quickly in one direction only using a fairly dry roller to minimize lap marks. For spray application use an airless spray gun with a .011 to .015 inch tip. Apply a wet coat of product by holding the gun no more than 10 inches from the hull. Do not use conventional spray equipment to apply this product. Apply at three mils wet to achieve a dry film thickness of 0.25 mils per coat.
Adhere to all application instructions, precautions, conditions and limitations to obtain optimum performance. Refer to individual labels and tech sheets for detailed instructions when using associated products, etc. Do no thin SR-21 more than 10% (2.5 ounces per quart kit) or inadequate paint film thickness will occur and premature erosion of the finish will be likely.
All surfaces must be clean, dry and properly prepared prior to painting. Coating performance, in general, is proportional to the degree of surface preparation. Follow recommendations carefully, avoiding shortcuts. Inadequate preparation of surfaces will virtually assure inadequate coating performance.
No antifouling paint can be effective under all conditions of exposure. Man made pollution and natural occurrences can adversely affect antifouling paint performance. Extreme hot and cold water temperatures, silt, dirt, oil, brackish water and even electrolysis can ruin an antifouling paint. Therefore, we strongly suggest that the bottom of the boat be checked regularly to make sure it is clean and that no growth is occurring. Lightly scrub the bottom with a soft brush to remove anything from the antifouling paint surface. Scrubbing is particularly important with boats that are idle for extended periods of time. The coating is most effective when the boat is used periodically.
