Peeling Paint on Walls – What Causes It?
Peeling paint on walls is often a sign that moisture is affecting the surface beneath the paint. When water becomes trapped within plaster or masonry, it can cause paint finishes to lose adhesion and begin to peel away from the wall.
Although repainting may temporarily improve the appearance of the wall, the problem will usually return if the underlying moisture source is not identified.
Several types of damp problems can cause paint to peel, including condensation, penetrating damp and rising damp.
What Does Peeling Paint on Walls Look Like?
Peeling paint often appears as flaking or lifting sections of paint where the surface separates from the plaster beneath. In some cases the paint may curl away from the wall or fall off completely.
The wall underneath may feel slightly damp or cold, and surrounding areas may also show signs of bubbling paint or damp staining.
Peeling Paint Caused by Condensation
Condensation is a common cause of peeling paint, particularly on external walls where surfaces remain colder. Moisture forming on walls over time can damage paint finishes and cause them to detach from the plaster.
This type of problem is frequently seen in bedrooms, kitchens and areas with poor ventilation.
Peeling Paint from Penetrating Damp
Penetrating damp occurs when water enters the building through defects such as cracked brickwork, damaged render, leaking gutters or roof problems.
When moisture soaks into wall materials from outside, it can cause internal paint finishes to peel or deteriorate.
Peeling Paint Caused by Rising Damp
Peeling paint near the base of walls may sometimes indicate rising damp. Rising damp occurs when moisture from the ground travels upward through masonry walls.
This moisture can damage plaster, paint finishes and timber skirting boards over time.
Peeling Paint on External Walls
External walls are often colder and more exposed to moisture, making them more prone to condensation and damp-related paint damage.
Peeling Paint Near Skirting Boards
When paint begins to peel near skirting boards or the base of walls, rising damp or moisture affecting lower wall sections may be responsible.
Peeling Paint After Damp Patches
Paint may begin to peel after damp patches develop because moisture weakens the bond between paint and plaster surfaces.
When Peeling Paint Should Be Investigated
If peeling paint continues to return after redecorating or spreads across walls, it may indicate an ongoing moisture problem within the property.
A professional damp survey can determine whether condensation, penetrating damp or rising damp is responsible.
