If the paint on your house is bubbling, is is usually due to one of the following reasons:
- The surface was not cleaned correctly before painting and dirt are blocking the new paint layer from adhering to the old paint beneath it.
- The surface was wet and the new paint could not bond to the surface below because of the dampness. This can be tested by opening one of the bubbles; if you see the most recent paint layer then the problem is with the most current layer of paint.
- The paint that is bubbling is actually the oldest paint or primer layers. This is fairly common in Portland’s older homes where the original layer of paint may be 80-100 years old. The new paint pulls on the older layers and they may no longer be firmly attached to the layers below them. You can confirm this by opening one of the bubbles and seeing the original layer of paint or primer, or even the bare wood siding.
At Weinmann Painting, we take care to wash and prepare your house properly, so that the new layers of paint will adhere firmly. Our estimators will also work with you to determine the best course of action for an older home that may need some or all of the paint removed to achieve the best result.
