How to treat water seepage and leakage on rising wall
Rising damp affects the lower region of walls because of rising ground water within the wall due to capillary action. This causes efflorescence (white deposit) and peeling of the paint.
1) Treating Mild Dampness in Interior Walls
Interior walls develop damp patches because of the aforementioned reasons. In case if these are mild patches, they can be treated without much hassle and effort. Remember to treat not just the patches but also at least 2 feet around the damp patch.
- Use an iron brush to remove loose material around in the area to be treated. Remove patches of loose plaster if needed.
- In case the plaster has been removed re plaster the patches using mortar made of cement, sand and a plasticizing additive chemical like Unicorn wall seal. Allow plaster to cure and dry out before the next step
- Apply a waterproof coating Unicorn Seal on the re-plastered area using the application instructions. This layer will prevent seepage and can also be used as a surface for repainting.
- The surface can now be repainted after surface preparation.
2) Treating Severe Dampness in Interior Walls
Severe dampness is characterized by peeling plaster, severe visible damp patches on the wall and white chalky deposits on the wall. To tackle this problem of water leaking from walls, the plaster has to be completely removed to apply waterproofing from the brick level.Unicorn chemical provides best water leakage and seepage solution in pakistan.
