Peeling, Bubbling paint on basement walls

Bubbling or peeling paint on basement foundation walls is usually a sign of a drainage problem in the home. The bubbling means that the vapor pressure of the moisture is exceeding the adhesion strength of the paint/sealer you applied. Basically, built up moisture in the wall is trying to push out of the foundation wall and bubbling the paint or sealer. The basement wall could be experiencing "blistering" or "efflorescence" or a combination of both. Blistering can be caused by trapped moisture trying to escape through the paint, and efflorescence is the crusty white salt deposits leached from the masonry or mortar as moisture passes through. In both cases the first part of the solution requires the elimination of moisture sources on both sides of your wall.

The elimination of moisture is different for every home. Some homes just need downspout extensions, some need proper grading of the lawn, some need external lawn drainage, and many need internal basement drainage systems to drain the hollow block foundation wall of water trapped inside of it. If you are unsure of the source of moisture and need help eliminating the vapor pressure of moisture on your basement walls, give us a call @ 1-877-409-2837 and setup an Free evaluation with one of our trained, certified inspectors.
