For maximum waterproofing performance, ensure the surface is clean, dry, and free from dust, grease, loose particles, algae, old flaking paint, and other contaminants. Repair all major cracks or damaged areas before application to create a stable and uniform surface.

For side walls, apply one coat of Dulux WS Alkali Bloc Primer or Dulux Professional WS E1000 Sealer as recommended. Alternatively, a self-priming coat of Dulux Aquatech Exterior Damp Protect Basecoat diluted with approximately 30% clean water can be used. After the primer has dried, apply one undiluted coat of Dulux Aquatech Exterior Damp Protect Basecoat and allow 6–8 hours of drying. Finish the system with two coats of a recommended Dulux Weathershield Exterior Paint for complete waterproofing and weather protection.

For roof waterproofing, thoroughly clean the roof and parapet surfaces before application. Apply one self-priming coat diluted with 30% water, followed by 2–3 undiluted coats using a brush or roller. Maintain a coverage of approximately 10–15 sq.ft. per litre to achieve the recommended film thickness required for effective waterproofing. Additional coats may be applied if necessary to ensure complete protection.

Allow the coating to dry properly between coats and avoid application during rain or extremely humid weather. Following the recommended application process ensures maximum adhesion, crack-bridging performance, and long-lasting waterproof protection.

At Dulux Newtown, we recommend following proper safety practices during all waterproofing applications. Avoid dry sanding, scraping, or burning old paint films, as these activities may generate hazardous dust and harmful fumes. Whenever surface preparation is required, wet sanding methods are recommended to minimize airborne particles.

Ensure adequate ventilation during application 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 out of reach of children and store it in a cool, dry place away from direct sunlight and extreme temperatures.
