Ensure the wall surface is clean, dry, smooth, and free from dust, grease, loose particles, old flaking paint, and other contaminants before application. Stir the product thoroughly to achieve a uniform consistency.

Apply two thin coats of Dulux Poly Putty, Dulux Acrylic Wall Putty, or Dulux Aquatech Waterproof Putty over the prepared surface. Allow the putty to dry completely and sand the surface using 180–220 grit emery paper to obtain a smooth finish. Remove all sanding dust before applying the basecoat.

Dilute Dulux Aquatech Interior Waterproof Basecoat with 50% clean water and apply one uniform coat at the recommended coverage of 180–200 sq.ft. per litre. Allow the coating to dry for approximately 3–4 hours before applying the selected Dulux interior topcoat according to its recommended application process.

Following the complete Dulux painting system helps achieve excellent waterproofing performance, smoother paint finish, improved adhesion, and long-lasting protection against mild interior dampness.

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