That spalling is happening because of moisture in the brick. The best fix is a proper cap on that chimney. It's even better when the chimney is in use, so the heat dries it out.
Partially correct. This house has spalling all over it, not just the chimney. The texture added to the brick causes it to retain moisture. To fix this I finished off the paint with Mineral Shield, which repels water, but also still lets the bricks breathe.
@@garrettscott9427 Given that you're the guy doing the work, it figures that you'll know the details. Some cheaper and more porus bricks are more prone to spalling over time. This is especially true if the house is old and has had any leaks before.
