Brick Waterproofing

Brick waterproofing is a clear treatment on the outside of a masonry chimney. It helps the brick shed rain. It is not a paint, and it is not a substitute for fixing cracks, open mortar, or a bad crown.

The work

What is brick waterproofing?

Masonry takes on water. In a freeze that water expands and the face of the brick breaks off. A breathable repellent slows that. The brick can still dry toward the outside, which matters because a film that traps water inside the wall makes the damage worse.

The chimney is looked at first. Spalled brick, missing mortar, or a cracked crown is repaired before any treatment goes on. Waterproofing over a hole does not stop the leak.

Why it matters

Why this work matters

A chimney that looks stained, or that grows a white crust on the brick, is taking on water. The crust is minerals left behind as the water evaporates. Treating the brick without finding where the water enters leaves the same path open.

Waterproofing is maintenance on sound masonry. It sits next to tuckpointing and crown work, not in place of them.
