A single pack bitumen coating, for the recoating of water tanks which are currently coated with bitumen, on canal boats and leisure craft or elsewhere. Complies to BS3416 (1991) Type 1, Class A. Legislation has resulted in the withdrawal of the Water Research Council’s approval of bitumen for use in water tanks and equipment for all public services on dry land. This means that bituminous solutions are no longer approved by the WRC, but their continuing use on existing bituminised tanks is permitted under BS3416 on boats. If your boat has a water tank already coated with bitumen, you can use Water Tank Coating to maintain it. New water tanks must use two pack bitumen-free coatings with WRAS/BS6920 approval, such as Epicol SF. For the internal coating of water tanks already coated with bitumen.
