One of the most serious problems you can have with your exterior paint is peeling. Paint peeling happens due to many reasons.
When paint peels, it exposes the surface it protects, making it vulnerable to the elements like moisture and heat from the sun. It is also an unappealing sight that calls attention.
So what do you do when you find that your exterior paint starts to peel? You simply don’t paint over that area without analyzing the cause. Here is what you should do:
If you find that the paint peeling happens in a limited area, like the area outside of your bathroom, then this means that moisture from the inside is the one that causes the peeling. The water from your bathroom seeps through the walls and into the paint, which, in effect, causes the paint to peel off the surface of the wall.
Bathrooms generate a lot of humidity or moisture, especially if you use water heaters, which produce a lot of steam. Moisture gets through the wall through the insulating material or sheath. If your walls are made of wood, it would only take some time for all the paint to peel.
Moisture usually gets through the walls when the insulating material is either damaged or of low quality. For the exterior paint to stop peeling, the moisture leak should first be stopped or resolved. Not only does the moisture leak cause your paint to peel, it will also cause the growth of molds and mildew in between your walls.
Have your walls checked first and installed with an insulating material if needed. You can also use dehumidifiers, if the area is not your bathroom. A dehumidifier is a device which absorbs the excess moisture in the air. Only after such things are done, that is the time you could repaint your exteriors.
