Step 2: Remove Existing Moisture from Walls
1. Ventilation
- Open windows and doors to allow fresh air circulation.
- Use exhaust fans in areas prone to moisture, such as kitchens and bathrooms.
2. Dehumidifiers
- Place a dehumidifier near the affected wall to pull excess moisture from the air and wall surface.
3. Use a Salt Solution
- Salt is a natural desiccant that can absorb moisture effectively.
- How to Use: Place bowls of rock salt near the damp walls. Replace the salt every few days until the wall dries.
4. Apply Heat
- Use a heater or blow dryer to dry small damp spots. For larger areas, consider using portable space heaters.
5. Baking Soda or Charcoal
- Place open containers of baking soda or activated charcoal near the walls to absorb moisture and reduce odors.
Step 3: Repair the Damage
1. Clean the Walls
- Scrub the wall with a mixture of water and white vinegar to remove stains and any mold growth.
- For stubborn mold, use a solution of bleach and water (1:4 ratio).
2. Repaint with Mold-Resistant Paint
- Once the wall is dry, apply a layer of anti-mold or water-resistant paint to prevent future moisture buildup.
3. Seal Cracks
- Use waterproof caulking or sealant to fill any cracks or holes in the wall to prevent water ingress.
Step 4: Prevent Moisture from Coming Back
1. Improve Ventilation
- Install vent fans in high-moisture areas like bathrooms and kitchens.
- Use air bricks to enhance airflow in poorly ventilated spaces.
2. Control Humidity Levels
- Keep indoor humidity levels between 30–50%.
- Use a hygrometer to monitor humidity levels.
3. Waterproof the Walls
- Apply a waterproofing solution or paint to exterior walls. This creates a barrier that prevents rainwater from seeping in.
4. Fix Leaks Immediately
- Regularly inspect plumbing and roofs for leaks and repair them as soon as possible.
5. Install a Damp-Proof Course
- For rising damp issues, consider installing or repairing a damp-proof membrane in your walls.
