Use: Removal of self-polishing antifouling, color black. Should be carried out in the open due to the smell. Highly recommended is the previous blasting with a strong pressure washer. After drying apply the stain with a brush. This is easy, but it creates a pretty goo, like tough honey. The stain also attacks household gloves and you should get some that are resistant to chemicals. \ R \ nThe recommended wooden scraper, I immediately exchanged for a metal spatula. The floor should be covered, color with stain also stick like honey. Repeated procedure several times, then blasted with the high-pressure cleaner. It's like squirting a oily surface. (maybe too dry?) Back remains an underwater ship, which still looks black, albeit with a thin layer. Will have to continue this in the spring then. Probably the only way to replace antifouling on a chemical basis.
