If you're searching for the best roof waterproof coating in Kolkata, PU waterproof coating for terraces, or a premium exterior waterproof solution in New Town, Dulux Aquatech Exterior PU Coat offers professional-grade performance for residential, commercial, and industrial buildings.

For the best waterproofing performance, thoroughly clean the roof, terrace, parapet, or wall surface by removing dust, dirt, grease, algae, loose particles, and old coatings. Ensure the surface is completely dry and repair any major cracks or damaged areas before beginning the waterproofing application.

Apply one self-priming coat of Dulux Aquatech Exterior PU Coat by diluting the product with up to 30% clean water. Once the primer coat has dried, apply 2–3 undiluted coats using a high-quality brush or roller. For maximum waterproofing performance, apply the second coat at a 90-degree angle to the first coat to achieve complete and uniform coverage.

Allow 5–6 hours of drying between each coat. To achieve the recommended dry film thickness (DFT), maintain a coverage of approximately 8–10 sq.ft. per litre on horizontal surfaces. If the required coverage or film thickness is not achieved, apply an additional coat. Following the recommended application process ensures maximum crack-bridging capability, superior waterproofing performance, and long-lasting durability.

At Dulux Newtown, we recommend following proper safety practices during every waterproofing application. Avoid sanding, burning, or scraping old paint films without suitable precautions, as these activities may generate hazardous dust and harmful fumes. Wherever possible, use wet sanding techniques to reduce airborne dust.

Always work in a well-ventilated area and wear appropriate personal protective equipment, including gloves, safety glasses, and a protective face mask. Avoid direct contact with skin and eyes, and wash thoroughly with clean water in case of accidental exposure.

Keep the product tightly sealed and store it in a cool, dry place away from direct sunlight. Keep out of reach of children. For complete technical specifications, handling instructions, and chemical safety information, please refer to the official Safety Data Sheet (SDS) available at Dulux Newtown. Following the recommended application and safety guidelines will help ensure outstanding waterproofing performance and a safe working environment.
