Begin by ensuring the wall surface is clean, dry, and free from dust, grease, loose particles, algae, fungi, chalk, and old flaking paint. Repair all cracks and damaged areas using the appropriate Dulux Aquatech Crack Filler or a cement-sand mixture. Lightly pre-wet the surface before application to improve workability and achieve better adhesion.

Mix Dulux Aquatech Waterproof Putty with approximately 30–40% clean water (by weight) until a smooth, lump-free paste is formed. Apply the first coat evenly using a steel trowel or putty knife, working from the bottom upward for uniform coverage and minimal material wastage. Allow the first coat to dry for at least 3 hours, then lightly smooth the surface using the putty blade to remove loose particles before applying the second coat.

Allow the second coat to dry completely for 8–10 hours, preferably overnight, before sanding lightly and proceeding with primer and topcoat application. Following the recommended application process ensures a smooth surface, improved paint adhesion, superior waterproofing, and long-lasting decorative finishes.
