How to Repair Water Damage Before Plastering

Water damage weakens walls and ceilings, causing staining, crumbling plaster, and mould growth. Proper repair before plastering ensures a smooth, durable finish.

Step 1: Identify the Source

Find the cause of the leak or damp. Common sources include:

• Roof leaks
• Plumbing issues
• Condensation in bathrooms or kitchens

Fixing the source prevents recurring damage after plastering.

Step 2: Remove Damaged Material

Cut out soft, swollen, or mouldy plaster and drywall. Remove debris for a clean working surface.

Step 3: Dry the Area

Use dehumidifiers, fans, or natural ventilation to completely dry walls and ceilings. Wet surfaces will prevent plaster from adhering properly.

Step 4: Treat Mould and Mildew

Apply anti-mould solutions to prevent regrowth. Professionals often treat underlying timber or plasterboard to ensure long-term protection.

Step 5: Reinforce and Repair

Replace or reinforce weakened sections with new plasterboard. Apply mesh tape over repaired joints to prevent cracking.

Step 6: Prepare for Plastering

• Sand rough edges
• Apply a bonding agent if needed
• Ensure walls are clean and dry
