Why Surface Preparation Matters
Skipping surface preparation is the number one cause of paint failure. Without a clean, sound surface, even the most expensive premium paint will peel, flake, or blister within months—especially in the diverse and challenging climates across India.
Step 1: Cleaning & Scraping
Remove all loose paint, dirt, and dust using a wire brush or scraper. For exterior walls, washing the wall with water (or a mild bleach solution for algae and fungus) is highly recommended to ensure the new coatings adhere properly.
Step 2: Crack Filling
Inspect the wall for cracks. Hairline cracks can be filled with standard wall putty. For structural cracks (wider than 2mm), use a specialized flexible acrylic filler like K-Seal Crack Fill to permanently prevent water seepage and maintain structural integrity.
Step 3: Applying Wall Putty
Apply two coats of Delite Wall Putty to create a glass-smooth, bright white surface. Allow 6-8 hours of drying time between coats, and sand lightly with 180-grit sandpaper for a flawless finish.
Step 4: Priming
Never skip the primer step. Primer seals the porous putty surface, prevents the wall from absorbing the expensive topcoat, and blocks alkali salts from new cement. Use Delite Cement Primer for interiors and Exterior Primer for outdoors.
