Rainy season can be a refreshing change from the heat, but for homeowners, it often brings an unwanted visitor: cracks in walls and ceilings. These cracks not only look bad but can also lead to water leakage, dampness, and long-term structural damage. If you’re tired of seeing your walls peel and crack every monsoon, it’s time to take proactive action. In this guide, we’ll explore how to prevent cracks in the rainy season, along with expert wall protection tips that will help you keep your home safe and leak-free.
Why Do Walls Crack During the Rainy Season?
Cracks form when there is a shift in the structure or expansion and contraction of building materials due to temperature and moisture changes. During the monsoon, excess moisture seeps into the walls through:
- Hairline cracks on the exterior walls
- Faulty or aged terrace waterproofing
- Gaps around windows, pipes, or joints
- Poor drainage systems
- Lack of waterproof coating or protection
Once moisture gets inside, it weakens the internal plaster and paint, causing bubbles, peeling, and eventually deep cracks.
Top Tips to Prevent Wall Cracks in Monsoon
1. Inspect for Early Cracks Before the Rains Begin
Check exterior and interior walls for hairline cracks or areas where paint is flaking. These are often the first signs of waterproofing failure. Treating them before monsoon helps you avoid bigger problems later.
2. Seal Cracks with Waterproof Crack Fillers
Use high-quality crack sealants that are flexible, durable, and waterproof. Products from brands like Dr. Fixit offer PU-based crack fillers that expand and contract with wall movement, preventing water entry.
3. Apply External Wall Waterproof Coating
Waterproof paint or coatings like Dr. Fixit Raincoat create a protective barrier on exterior walls. They block water penetration, reduce heat absorption, and increase the life of your walls.
4. Ensure Terrace Waterproofing is Intact
Often, cracks originate from water entering through the terrace. Make sure your terrace is properly sealed with liquid membrane coatings or PU-based waterproofing systems.
5. Use Weather-Proof Plaster for Repairs
Regular cement plaster may not hold up during heavy rains. Use polymer-modified mortar or additives like SBR latex with cement for patchwork to improve water resistance.
6. Improve Drainage Around the House
Ensure that water drains away from your building foundation. Clogged or broken drainage pipes often lead to water collecting at the base, causing cracks and rising dampness.
Monsoon Wall Maintenance Tips
- Clean your gutters regularly to avoid overflow onto walls.
- Trim nearby trees whose roots may damage foundations.
- Fix broken plumbing or seepage from overhead tanks.
- Keep indoor humidity low to avoid condensation on walls.
- Repaint interiors every 3–5 years with damp-proof emulsions.
