Wall Dampness Treatment

Wall dampness is a common issue caused by moisture penetrating through walls, which can lead to mold growth, paint peeling, and structural damage. Treating damp walls effectively is essential for maintaining a dry, healthy environment. Here’s a step-by-step guide on wall dampness treatment.

Identifying the Source of Moisture

Rising Damp: Groundwater rising through porous materials, such as bricks and mortar, due to capillary action.
Penetrating Damp: Water enters from outside due to cracks, faulty gutters, or poor external wall conditions.
Condensation: Moisture forms inside buildings due to poor ventilation and high humidity levels.

Surface Preparation

Removing Damaged Plaster or Paint: Scraping off flaking or damaged material is necessary to prepare the wall for treatment.
Cleaning the Surface: Mold and mildew should be removed using appropriate fungicidal washes to prevent further growth.
Drying the Area: High-powered fans or dehumidifiers are used to ensure the area is completely dry before applying treatment.

Application of Waterproofing Agents

Damp-Proof Paint or Sealants: Special waterproof paints can block moisture from penetrating the wall surface.
Waterproof Membranes: Installing membranes creates a physical barrier to prevent moisture penetration.
Chemical Injection: Injecting damp-proof chemicals into the wall forms a barrier to rising damp, stopping water movement.

Repair and Finishing

Replastering: After applying treatment, the wall is replastered using moisture-resistant materials.
Repainting: Once the surface is dry, repaint using breathable, mold-resistant paints.
