How to Fix Mould-Damaged Ceilings Before Painting
Mould-damaged ceilings should not simply be painted over. Moisture, staining, surface damage, and ventilation issues need to be addressed first.
Find the moisture source first
Before repainting, the cause of mould or staining should be understood. Common issues include roof leaks, bathroom ventilation problems, condensation, or previous water damage.
Painting over active moisture can lead to stains returning, peeling paint, and recurring mould marks.
Prepare and seal the affected area
Once the source is resolved, the ceiling may need cleaning, surface repairs, sanding, stain blocking, and a suitable primer before repainting.
Badly affected plaster, flaking paint, or soft ceiling areas may need repair before any finish coat is applied.
Choose the right repaint system
Ceiling repainting after mould damage often needs more than standard ceiling paint. The coating system should suit the room, ventilation, and surface condition.
