How to Fix Peeling Paint on External Walls

It’s a familiar scene in many African homes: that once-vibrant wall outside your house is now flaking, chalky, or peeling. Sun, rain, poor materials… and suddenly your curb appeal is gone.

We don’t just sell paints at Aycee Builder; we understand what makes it fail or flourish, especially in African climates. In this expert guide, we show you how to fix peeling paint properly, and more importantly, how to prevent it for good.

What Causes Peeling Paint on External Walls?

Understanding the why helps you prevent a repeat.

1. Poor Surface Preparation

Dirt, moisture, old paint residue, if you paint over it, it’s a ticking time bomb.

2. Use of Low-Quality Paint

Cheap exterior paint simply can’t handle Nigeria’s tropical heat and heavy rains.

3. Lack of Primer or Sealant

Primer is what helps paint bond to the wall and resist weather.

4. Dampness in the Wall

This is common in areas with poor drainage, roof leaks, or rising ground moisture.

Tip: Never paint a wall that feels “cool” or damp to the touch—it’s a recipe for peeling.

Step-by-Step: How to Fix Peeling Paint on External Walls

Step 1: Scrape and Strip Off Old Paint

• Use a paint scraper or wire brush to remove all loose paint.
  
  

• Don’t just patch over it—go deep until you reach a solid base.

Step 2: Check for Moisture

• Look for cracks, signs of algae, or damp patches.
  
  

• If damp, fix the source first (roof leak, faulty plumbing, no damp-proofing)

Step 3: Apply Filler or Skim Coat (if needed)

• Fill all cracks or gaps using cement-based filler or exterior skim compound
  
  

• Sand smooth after drying

Step 4: Use Exterior Primer

• Primers seal the surface, enhance adhesion, and prolong paint lifespan.
  
  

  Go for alkali-resistant primers on new cement walls.

Step 5: Repaint with Premium Exterior Paint

Choose paint that’s:

• UV-resistant (to prevent fading)
  
  

• Waterproof
  
  

• Anti-fungal
  
  

• Low-VOC (for better air quality)

  We recommend elastomeric or textured paints for added protection.
