How to Resurface a Brick Chimney

A well-maintained brick chimney adds charm and character to your home, but over time, weather and natural wear can cause the masonry to deteriorate. Resurfacing is a great solution to restore its look and structural integrity, but knowing how to do it right can be a challenge. In this guide, we’ll walk you through the steps to resurface a brick chimney. But remember, working at height and with masonry can be very dangerous. For a flawless finish and long-lasting results, consider reaching out to the exterior renovation experts at Innovative Exteriors to handle the job safely and professionally.

Restore Your Chimney’s Look and Integrity

1. Inspect Your Chimney for Damage

Before beginning any resurfacing project, make sure to inspect your chimney closely. Look for signs such as cracks, discoloration, or chipped bricks.

• Cracks in the mortar – These are common in aging chimneys and need to be repaired to maintain the structure’s integrity.
• Spalled or broken bricks – Spalling occurs when water infiltrates the brick, causing it to chip or flake off.
• Discoloration – Stains can indicate water damage, mold, or rust from chimney caps and liners.

If your inspection reveals significant structural issues, consulting professionals like Innovative Exteriors will save you from further complications. A trained team can assess the best methods to stabilize and protect your chimney’s structure.

2. Clean the Chimney Surface

Dirt, debris, and moss build-up can prevent new mortar from adhering properly. Use a stiff-bristle brush to scrub the chimney’s surface, or consider a power washer on a low setting if the dirt is stubborn. Once you’ve removed surface debris, allow the chimney to dry completely before moving forward with resurfacing.

3. Apply a Bonding Agent

A bonding agent acts as a glue between the old and new layers of mortar. This step ensures the new surface layer adheres firmly, preventing future chipping or peeling. With a masonry brush, apply the bonding agent evenly over the chimney’s surface and allow it to dry as directed by the product instructions.

4. Mix and Apply Mortar

Choose a mortar mix designed for masonry repair. Follow the instructions to mix the mortar to the right consistency, ensuring it’s thick enough to stick but still spreadable. Using a trowel, apply the first thin layer of mortar onto the chimney, focusing on smoothing it into a uniform coat. For best results, work in small sections to ensure the mortar does not dry out before it’s finished. This is where the expertise of professionals, like those at Innovative Exteriors, really comes in handy. Achieving an even coat across your entire chimney can be challenging without the right tools and experience.

5. Add a Finish Coat

Once the base layer has been set, apply a second, thinner coat for a smooth finish. If desired, you can texture this final layer to match your home’s exterior style or create a sleek, modern look. A finishing coat protects the chimney from the elements, enhances durability, and improves appearance.

6. Cure the Mortar and Seal the Surface

Allow the mortar to cure completely, which can take a few days depending on the weather. Finally, apply a high-quality masonry sealer to protect the chimney from moisture. Regular sealing will help prevent future damage and keep your chimney looking fresh for years.
