Damp walls are a condition where house walls appear damp, making the wall temperature feel cold and showing stains from water seepage. This can lead to the growth of mold and cause the peeling of exterior wall paint.
Besides making house occupants uncomfortable, damp walls can also cause health problems if left untreated. Some health problems that can be affected include shortness of breath, infections, or even skin irritation.
There are several causes of dampness on walls, including:
- Leaking Pipes or Gutters
Some parts of walls usually serve as pathways for water pipes or gutters during rain from the roof. If these pipes or gutters leak, water will seep into the walls, and stains from water seepage will be visible on the upper part of the wall.
- Imperfect Plastering Process
The wall finishing process definitely involves a plastering process with cement mixture and additives such as waterproof and anti-fungal layers. If the plastering or coating process is not completely dry, the walls will easily absorb water, leading to dampness.
Usually, the wall plastering process will dry within 5 to 7 days. However, specifically for buildings located in densely populated areas and with little sun exposure, the plastering process can take more than 7 days.
- Room Conditions Adjacent to Wet Areas
Damp walls can also occur in rooms close to wet areas. For example, rooms adjacent to bathrooms.
Continuously flowing water will increase wall humidity and easily cause dampness.
A common consequence of damp walls is paint peeling or the appearance of hairline cracks on the outermost paint layer. If this occurs, the most effective way to deal with damp walls is by using a waterproofing layer or a leak-proof coating paint.
