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.

When painting brick, each application method has distinct advantages and disadvantages. Spraying is significantly faster but may not penetrate deeply beyond the surface layer. Rolling is effective for working paint into the brick's texture but can be less effective on mortar joints. If you opt for a roller, choose a thick nap of at least a half-inch to ensure paint gets into all the crevices for even coverage. Using a brush is generally not recommended as it is very time-consuming and provides poor surface penetration. Ultimately, a combination of spraying followed by back-rolling is often the best strategy for a durable and even finish.

Drilling into brick or mortar requires the use of a masonry drill bit. Masonry drill bits appear similar to standard drill bits except for the leading tip of the bit. The tip has a bulky carbide arrow-shaped end slightly larger than the rest of the bit shaft. Standard or high-speed drill bits designed for making holes in wood or metal don’t have the ruggedness or design shape you need to drill into brick. They may not go through the brick at all, and if they do, they’re more likely to overheat, crack, or dull before you finish drilling.

For most brick cleaning jobs, including fireplace bricks, use a masonry sponge and a gentle cleaner. A simple solution of equal parts water and vinegar, or a few drops of dish soap in a bowl of water, can effectively remove grime. For tougher stains, you can use a dedicated masonry or fireplace cleaner. It is crucial to wet the bricks thoroughly with water before applying any cleaning solution to prevent the brick from absorbing it, and to rinse the surface completely afterward. Harsher cleaners containing bleach or ammonia should only be used as a last resort, and they should never be mixed together.
