Why Your Paint Keeps Peeling — and How to Fix It Permanently

🏠 Why Paint Starts Peeling in the First Place

Peeling paint is one of the most common and frustrating problems for homeowners in Kenya. You paint your walls beautifully, only to see the paint begin to bubble or flake off a few months later. The good news? It’s not permanent — and in most cases, it’s preventable.

Before fixing it, it’s important to understand why it happens.

🔍 Common Causes of Peeling Paint

1. Dampness or Moisture Under the Paint
   • This is the number one cause in bathrooms, kitchens, and exterior walls.
   • When moisture seeps through the wall, it pushes the paint layer outward, causing blisters and flakes.
   • Solution: Use anti-damp products like Crown Damp Protek or waterproof coatings before repainting.
2. Poor Surface Preparation
   • Painting over dust, grease, or old peeling paint prevents proper adhesion.
   • Solution: Always clean, sand, and prime the surface before painting.
3. Skipping the Primer
   • Primer creates a strong bond between the wall and paint. Without it, the topcoat easily separates.
   • Solution: Apply a quality primer like Crown Alkali Resistant Primer or Crown Universal Undercoat.
4. Using Low-Quality or Incompatible Paint
   • Cheap or mismatched paints can react badly with previous coats or humidity.
   • Solution: Use trusted brands available at Rangi Paint Store, where quality and performance are guaranteed.
5. Painting on a Damp or Uncured Wall
   • Fresh plaster takes time to dry. Painting too soon traps moisture inside.
   • Solution: Allow plaster to cure completely (at least 2–4 weeks) before painting.
6. Extreme Temperature or Sun Exposure
   • Direct heat can cause paint to dry too fast and lose adhesion.
   • Solution: Use weather-resistant paints like Crown Permacote Ultraguard Silicone Paint for exteriors.

🧰 Step-by-Step: How to Fix Peeling Paint Permanently

Follow these steps to restore your walls and prevent future peeling:

1. Scrape Off All Loose Paint
   • Use a paint scraper or wire brush to remove every flake of peeling paint.
2. Clean the Surface Thoroughly
   • Wash with mild detergent and water to remove dirt, oil, or mould.
   • Treat any mould with a fungicidal wash to kill spores before repainting.
3. Repair Any Cracks or Holes
   • Use filler or putty to smooth out imperfections, then sand the surface flat.
4. Prime the Wall
   • Apply one coat of Rangi Universal Undercoat or Crown Alkali Resistant Primer.
   • Let it dry completely for a stronger bond.
5. Apply a High-Quality Topcoat
   • For interior walls: use Rangi Silk Emulsion Paint for a smooth, washable finish.
   • For humid areas like bathrooms: use Crown Medicryl Anti-Bacterial Silk Sheen.
   • For exteriors: choose Crown Permacote Ultraguard Silicone Paint — water-repellent and weatherproof.
6. Ensure Good Ventilation
   • Allow the paint to dry naturally in a well-ventilated area to avoid moisture buildup.
