Why Paint Peels in Older London Homes

 

Peeling paint is common in older London properties. It may appear as bubbles, flakes or damp marks near the floor, windows or external walls.

In period homes across Hampstead, Kensington and Holland Park, the problem is often caused by trapped moisture rather than poor-quality paint. Repainting the wall without fixing the cause usually provides only a temporary result.

Find the Cause Before Repainting Damp Walls

Paint may peel because of:

• Condensation
• Plumbing leaks
• Poor ventilation
• Damp plaster
• Cracks in external walls
• Unsuitable previous paint
• Inadequate surface preparation

The wall should be inspected before decorating begins. Any active leak or ventilation problem must be addressed first.

Painting directly over damp areas can cause the new finish to bubble and fail again.

Use Breathable Paint in Period Properties

Many older London homes have traditional lime plaster or solid walls. These materials need to release moisture naturally.

Modern vinyl paint can seal the surface and trap water vapour inside the wall. This may lead to flaking paint, powdery plaster, stains and mould.

Breathable mineral paint, limewash or another compatible coating may be more suitable. The correct product depends on the wall condition and existing materials.

Repair the Surface Before Applying New Paint

Loose paint and damaged plaster must be removed carefully. The wall should then be allowed to dry.

Preparation may include:

• Removing unstable coatings
• Repairing small cracks
• Restoring damaged plaster
• Applying breathable primer
• Improving airflow around furniture
• Using a compatible final finish

Good preparation helps the new decoration last longer.

Damp Wall Repair in Belsize Park

A bedroom near Belsize Park Gardens had been repainted twice, but the paint continued peeling.

Dense modern paint had trapped moisture inside older plaster. Poor airflow behind a wardrobe made the problem worse.

The unstable coating was removed, the wall was dried and repaired, and a breathable paint system was applied. The furniture was also moved slightly away from the wall to improve ventilation.
