How to Fix Peeling Wall Paint Caused by Moisture
What Is Peeling Interior Paint?
Loss of adhesion of the paint film caused by high levels of moisture exposure on a wall, ceiling or trim. Over time, moisture penetrates the film and eventually pushes it away from the painted surface.
What Causes It?
- Excessive moisture in a home resulted from cooking, showering, or the use of a humidifier, vaporizer or hot tub.
- Excessive moisture in a home due to a high level of humidity in the basement and/or foundation.
Solutions for Peeling Paint Caused by Moisture
- Proper ventilation can fix most interior moisture problems. High-moisture areas such as bathrooms with showers should have exhaust fans installed.
- Proper ventilation in the walls and/or roof of the home may be necessary. Heavily insulated and sealed homes need a means for moisture to escape, such as roof vents and possibly outside wall vents.
- Another option is to allow moisture to escape via open windows.
- If high levels of moisture and humidity exist in a basement, the cause of this must be determined and fixed.
- Once proper ventilation has been installed, peeling paint should be removed and the underlying surface cleaned and primed.
- Test the coating in a six to 12 inch radius around any peeled areas to be sure its adhesion is adequate. Follow label and data page directions for proper surface preparation.
