As time goes by, walls in homes or buildings can get damaged—like cracks, wet spots, peeling paint, or mold. These problems aren’t just for looks; they often mean there is water leaking or that the walls are not well-protected from water. If you are fixing up a home or dealing with a long-lasting issue, making the walls waterproof and repairing them should be very important.
Why Wall Waterproofing is Important
Water can slowly get through concrete or cracks in walls, especially during rainy seasons or in humid places.If not treated, it can cause:
- Weak walls.
- Mold and mildew (which can harm health).
- Damage and color change to wall paint.
- Higher maintenance costs.
Steps to Fix and Waterproof Walls
1. Check for Damage
Look at both inside and outside walls for:
- Cracks
- Paint that is bubbling or peeling
- Wet spots or musty smells
- Mold or white salt marks
2. Prepare the Surface
Before fixing, clean the area well:
- Remove loose paint, plaster, and dust
- Fill cracks with good quality filler
- Let it dry completely
3. Apply Waterproof Treatment
Use waterproof products based on the wall type and how bad the damage is:
- For inside walls: Use breathable waterproof putty or primers
- For outside walls: Use UV-resistant waterproof paints
- For serious dampness: Use injection grouting to seal leaks inside
4. Repaint or Finish
After waterproofing, repaint with moisture-resistant paints for better lasting and a fresh look.
