Prepare the surface by removing all loose plaster, putty, dust, grease, oil, algae, and other contaminants. Repair any damaged areas or cracks using Dulux Aquatech Crack Filler or a suitable polymer-modified repair mortar. Before application, thoroughly pre-wet the surface until it reaches a saturated surface dry condition to improve bonding.

Mix Dulux Aquatech Waterblock 2K by combining the powder and liquid components in a 2:1 ratio by weight. Pour the liquid component into a clean mixing container and gradually add the powder while continuously mixing with a low-speed mechanical stirrer (200–300 RPM) for 5–6 minutes until a smooth, lump-free slurry is obtained.

Apply two coats using a masonry brush or suitable spray equipment. For interior walls, maintain a coverage of 10–15 sq.ft./kg, allowing the first coat to dry for 1–2 days before applying the second coat. After the final coat, allow 4–6 days of curing before proceeding with primer, putty, and topcoat applications.

For concrete roofs, water tanks, swimming pools, and sunken areas, follow the recommended coverage guidelines and ensure complete curing before exposing the treated surface to water. During the curing period, protect the coating from direct sunlight and maintain damp curing where required to achieve maximum waterproofing performance.

At Dulux Newtown, we recommend following proper safety precautions during waterproofing applications. Surface preparation methods such as sanding, scraping, or removing old coatings may generate hazardous dust and harmful fumes. Whenever possible, use wet sanding techniques to minimize airborne particles and improve workplace safety.

Always work in a well-ventilated area while wearing appropriate personal protective equipment, including gloves, safety glasses, and a protective face mask. Avoid direct contact with skin and eyes, wash thoroughly after handling, and keep the product out of reach of children.

Store the product in a cool, dry place away from moisture and direct sunlight. For complete technical specifications, handling instructions, and safety recommendations, please refer to the official Safety Data Sheet (SDS) available at Dulux Newtown. Following the recommended mixing ratio, application procedure, and curing process will ensure superior waterproofing performance, maximum durability, and long-lasting protection against water seepage.
