Easy DIY Solutions for Dampness in the Basement

Dampness in lower walls

Rising DampCan occur in any season, not just during the rainy season, because whenever moisture creeps close to the walls of the house, this problem can arise. Before mold starts to appear, let’s learn how to solve the issue of rising damp together!

 

What causes rising damp?

Rising damp occurs due to the accumulation of moisture at the lower walls or areas close to the ground. The moisture can come from various sources, such as moisture from the soil, groundwater seeping up the walls, rain splash, watering plants, building houses near water sources, water pooling, or poor drainage systems.

The moisture accumulated at the lower part of the house will cause the paint film to lose its adhesion to the wall surface, leading to paint blistering and peeling, followed by mold or black stains, musty odors inside the house, and some structural deterioration over time. Homeowners should address this issue promptly.

How to solve rising damp

Managing the problem of rising damp should start with surface preparation, removing mold, and then applying a primer and topcoat as needed, following these steps:

1. Prepare the surface properly

First, scrape off the blistered and peeling paint film using a metal scraper, and sand off the first 2-3 feet of the paint film completely (down to the bare concrete) with sandpaper.

2. Remove mold and algae

If the concrete surface has mold or algae stains, apply a mold and algae remover, Beger MouldFree M-001, in one coat without rinsing off. Wait until it is completely dry before proceeding to the next step.
