The prolonged rainy season in Indonesia often brings its own challenges to the condition of your home's walls. It's not just the exterior walls that are vulnerable; interior walls can also be affected, especially if your house is adjacent to a neighbor's or has imperfect roof sealing.
Damp and moldy interior walls are not just an aesthetic issue. Persistent dampness can damage the wall structure, spread mold spores that are harmful to respiratory health, and ruin surrounding furniture and belongings. Addressing this problem as early as possible is far better and more economical than waiting until the damage worsens.
How do you keep your home's walls dry and healthy during the rainy season? Check out the complete guide below!
The Impact of the Rainy Season on Your Home's Walls
High rainfall intensity during the rainy season significantly increases moisture levels in the air and soil. This condition creates continuous water pressure on wall surfaces, especially walls directly bordering open areas or attached to other buildings.
1. Seepage from Neighboring Walls
One of the most common problems experienced by homeowners in Indonesia is damp interior walls caused by seepage from neighboring walls. This happens when the dividing wall between two houses lacks an adequate waterproofing layer, causing rainwater that soaks into the neighbor's wall to seep into yours. The result is blistering, peeling wall paint, and even stubborn mold patches.
2. Causes of Damp Walls and Peeling Paint
Besides seepage from neighbors, several other factors cause damp walls in the rainy season, including: hairline cracks in the wall that act as water entry points, poor room ventilation preventing moisture from escaping, condensation due to temperature differences between indoors and outdoors, and clogged gutters causing water to overflow onto facade walls.
Tips for Maintaining Wall Conditions During the Rainy Season
There are several preventive measures you can take to minimize the impact of the rainy season on your home's walls.
1. Regularly Inspect and Patch Wall Cracks
Conduct regular wall inspections, especially before the rainy season, to find any small cracks that may have formed. Even the smallest crack can become a significant water entry point during days of heavy rain. Patch them using mortar or a special sealant before the cracks grow larger.
2. Ensure Drainage Systems and Gutters Function Properly
Gutters clogged with leaves or debris will cause rainwater to overflow onto facade walls and seep inside. Clean gutters at least twice a year, especially before the rainy season arrives. Also, ensure the drainage system around the house's foundation flows smoothly so rainwater doesn't puddle and soak into the base of the walls.
3. Improve Indoor Air Ventilation
Good air circulation is crucial to prevent moisture buildup indoors. Open windows and doors during the day to allow fresh air in and moist air out. For rooms with limited ventilation, consider using an exhaust fan or dehumidifier to keep moisture levels low.
The Importance of Using Leak-Proof and Anti-Damp Protective Paint
If seepage has already occurred, the most effective long-term solution is not just repainting the wall with regular paint, as ordinary paint cannot withstand water pressure from inside the wall. What is needed is a special protective coating capable of blocking seepage from the inside while protecting the surface from continuous moisture.
