While painting can certainly change the look of a chimney, you should think twice about giving your brick chimney the old landlord special.

Painting brick is porous, meaning it’s full of tiny holes that can soak up moisture. Those holes also allow it to dry, though. So, when you paint it, you trap any moisture inside, providing an opportunity for mold, mildew, and water damage.

Paint also shows wear faster than naked brick. This means that once you paint a brick surface, you’ll have to keep painting it to maintain a clean look. A paint job is also harder to undo on brick because of its porous nature. Once you paint it, it’s hard to go back without some serious power washing—another added cost.

You will repoint over a fraction of the old mortar, but you should scrape away 1/2 to 1 inch of mortar from the joints before repointing. Otherwise, the repointing is only masking the weakened mortar instead of actually replacing it, which could put your chimney at risk of bigger, more expensive damages later on.

Yes, you can paint stone on the exterior of a house. It’s important to properly prep the stone by cleaning off dirt and debris. You’ll want to apply at least two coats of paint to get the most even and complete coverage. Any pinholes or missed spots, however small, can allow moisture to get into the masonry and potentially cause the paint to blister and peel from the stone.

Stone houses used to be much more practical, but with the advent of stronger and cheaper materials like concrete, they aren’t seen as much anymore. There are some parts of the world where it makes sense to build with stone, and they are usually next to a stone quarry. Stone is, however, very weather-resistant, which is why many homes near the sea and on mountains are still built with local stone.
