 To guarantee maximum lifespan and flawless rainfall protection from this premium soft sheen exterior emulsion in New Town, follow this expert step-by-step application process recommended by the technical team at Dulux Newtown, Kolkata. 
Step 1: Surface Preparation & Root Treatment

Ensure the exterior masonry surface is completely clean, dry, and thoroughly free from loose dirt, chalky residue, grease, algae, fungi, or old flaking paint layers. Achieve a stable base by scrubbing the walls firmly with a stiff wire or coir brush, followed by high-pressure water jetting if required. Apply a uniform layer of Dulux Aquatech Pre Treatment Coat to ensure all underlying algae and fungi spores are entirely wiped out from the roots. Note: Application of standard wall putty is strictly not recommended for this exterior protection framework.
Step 2: Topcoat Application (Waterproofing vs Normal Process)

With Waterproofing System: Apply one solid base coat of Dulux Exterior Acrylic Primer or Dulux Weathershield Alkali Bloc Primer after thinning with clean water in a 1:1 ratio by volume, OR self-prime using Dulux Aquatech DampProtect Basecoat at 30% dilution. Next, apply 1 full coat of DampProtect Basecoat without any dilution as your heavy-duty waterproofing layer. Once dry, apply 2 to 3 topcoats of Dulux Weathershield Protect Rainproof, allowing a drying window of 4 to 6 hours between coats.

Normal Application System: Apply one standard priming coat of Dulux Exterior Acrylic Primer or Alkali Bloc Primer thinned 1:1 with water. Over this dried base layer, apply 2 to 3 coats of Dulux Weathershield Protect Rainproof, ensuring a strict 4 to 6 hours drying interval between subsequent layers.

Important Pro-Tip: An additional protective coat should always be applied over horizontal surfaces like the top of window ledges, sunshades, and parapet walls where water tends to collect.
Step 3: Drying Time

This quick-setting exterior formula becomes pleasantly touch dry in up to 30 minutes, while the recommended technical window for safe recoating is 4 to 6 hours.
