How to Stop Damp Walls During Rainy Months in the Philippines

Damp walls are a common headache for Filipino homeowners. During the rainy season, walls absorb water like a sponge. If you do nothing, the problem gets worse. Mold will grow, paint will peel, and your house could start smelling musty.

Why Do Walls Become Damp?

  • Rainwater Leaks – Cracks in the walls or roof let rainwater in.

  • Poor Waterproofing – If your walls were not sealed properly before painting, moisture can get trapped inside.

  • High Humidity – Our climate keeps the air moist, making walls take longer to dry.

What Happens If You Ignore Damp Walls?

If you let damp walls stay wet, you’ll face these problems:

  • Peeling paint

  • Mold growth

  • Bad smells

  • Structural damage over time

How to Prevent Damp Walls

1. Fix Leaks Immediately

Find out where the water is coming from. Is your roof leaking? Are your gutters clogged? Fix these problems first.

2. Waterproof Your Walls

Before painting, use a waterproofing primer. This protects your walls from absorbing water.

3. Use Breathable Paint

Paints like Asvesti Limewash Paint allow moisture to escape from the walls. Limewash also stops mold naturally, which is a big help during the rainy season.

4. Improve Ventilation

Keep windows open when possible, or use exhaust fans to help dry out the walls faster.

5. Clean and Maintain Walls

Regularly wipe walls to remove any early signs of moisture or mold.
