Introduction
Rising damp is a common issue in older properties, particularly those that lack adequate damp-proofing. It occurs when moisture from the ground rises through the walls of a building, leading to a range of problems including peeling paint, mould growth, and structural damage. If left untreated, rising damp can lead to significant repair costs and a decrease in property value. This guide will help you identify and address rising damp in your home.
Required Tools/Materials
- Damp meter
- Moisture-resistant paint
- Damp-proof membrane (if required)
- Plastering tools
- Brushes and rollers
- Protective gloves
- Face mask
- Spanner
- Sealant
Step-by-Step Instructions
1. Identify the Symptoms of Rising Damp
Look for the following signs:
- Peeling paint or wallpaper
- Mould or mildew growth
- Salt deposits on walls
- Wet patches at the base of walls
2. Use a Damp Meter
Purchase or borrow a damp meter to measure the moisture levels in your walls. A reading over 20% typically indicates rising damp.
3. Investigate the Source
Check the exterior of your property for potential sources of moisture:
- Blocked gutters or downpipes
- Cracked or damaged walls
- Poor drainage around the foundation
4. Apply a Damp-Proof Course
If rising damp is confirmed, consider installing a damp-proof course. This may involve the following:
- Removing existing plaster to the affected area
- Applying a damp-proof membrane
- Replastering the wall with a moisture-resistant plaster
5. Treat Mould and Mildew
Use anti-fungal spray to treat mould and mildew. Ensure the area is well-ventilated while you work.
6. Repaint with Moisture-Resistant Paint
Once the wall is dry, repaint with moisture-resistant paint to prevent future issues.
