Acothane DW is a Solvent Free Polyurethane Coating for water tank lining and relining. This product is approved for use in public water supplies. It forms a corrosion and also erosion resistant protective coating for the refurbishment of all types of water and liquid retaining structures.

Use this product on concrete, steel and also glass reinforced plastic (GRP). It forms a long lasting and water tight solution to tank lining, with outstanding physical properties in terms of flexural strength, tensile strength, impact and abrasion resistance.

Use for metallic, cementitious, composite and GRP tanks, vessels, reservoirs ,pipelines, pipe bends and random lengths, valves and fittings holding or transporting drinking water. As well as waste water sewage and sludge and most trade effluent tanks, vessels and bund areas.

We’ve carefully categorised our products so you can easily find the right coating based on surface type, project use, or area of application - like floors, metal, kitchens, or outdoors.

Some products do cross over between categories (for example, a floor paint that also works on metal) but rest assured - we’ve placed them where they’re most commonly used.

Still unsure? Just drop us a message - we’re happy to help you choose the best fit for your specific project.
