Ensure the exterior wall surface is clean, dry, and free from dust, grease, algae, fungi, loose particles, old paint, and other contaminants. Repair any damaged or cracked areas before beginning the waterproofing application to achieve maximum adhesion and durability.

Apply one coat of Dulux WS Alkali Bloc Primer, Dulux Professional WS E1000 Sealer, or a self-priming coat of Dulux Aquatech Flexible Waterproof Basecoat Advance diluted with approximately 30% clean water. After the primer has dried, apply one undiluted coat of Dulux Aquatech Flexible Waterproof Basecoat Advance and allow it to dry for 6–8 hours.

Once the waterproof basecoat is completely dry, apply two coats of Dulux Weathershield Powerflexx or Dulux Professional WS Flexx following the recommended dilution guidelines. Maintain a drying interval of 6–8 hours between coats and ensure the recommended coverage of 30–45 sq.ft. per litre is achieved to obtain the required film thickness for effective waterproofing. If the specified coverage is not achieved, apply an additional coat to maximize waterproofing performance and ensure long-lasting exterior wall protection.

Whenever possible, use wet sanding techniques to minimize airborne particles and create a safer working environment.
