Transform Your Space: Tiling Over an Existing Brick Fireplace
Are you looking to update the look of your brick fireplace but aren't ready to tear it down? Tiling over an existing brick fireplace is a great way to refresh your space while adding a touch of elegance. This guide will walk you through the process, from preparation to completion, ensuring a professional finish that you'll love.
Understanding the Benefits and Challenges
Before you start, it's essential to understand the pros and cons of tiling over brick. On the plus side, tiling can update the look of your fireplace, making it a focal point in your room. It's also a cost-effective alternative to removing the brick entirely. However, keep in mind that tiling over brick can make the fireplace more difficult to clean and may not be suitable for all types of brick or fireplace configurations.
Gather Your Tools and Materials
- Thinset mortar
- Tile adhesive
- Tile nippers
- Trowel
- Notched trowel
- Level
- Grout
- Sponge
- Sealer
- Tiles of your choice
Prepare the Brick Surface
The success of your tiling project depends on a smooth, clean surface. Start by removing any loose mortar or debris from the brick. Then, using a damp cloth, clean the brick to remove any dirt or residue. Allow the brick to dry completely before proceeding.

Apply Thinset Mortar
Thinset mortar is a flexible adhesive that's ideal for tiling over brick. Using a notched trowel, apply the thinset to the brick, ensuring full coverage. Work in small sections to prevent the mortar from drying out before you can apply the tiles.
Lay Out and Install the Tiles
Before you start laying tiles, plan your pattern on the floor to ensure a balanced look. Once you're ready, start at the bottom of the fireplace and work your way up, using a level to ensure each row is straight. Apply tile adhesive to the back of each tile using the notched trowel, then press the tile firmly into the thinset on the brick. Use spacers to maintain even grout lines.
Cutting Tiles to Size
You'll likely need to cut some tiles to fit around the fireplace opening or to fit the last row. Use a tile nipper to score and snap the tile, then smooth the edge with a wet saw or file. Always wear safety glasses when cutting tiles.

Applying Grout
Once the tiles have set (usually after 24 hours), it's time to apply grout. Mix the grout according to the package instructions, then use a rubber float to spread it over the tiles, forcing it into the grout lines. Allow the grout to set for about 15 minutes, then use a damp sponge to wipe away excess grout from the tile surface.
Sealing and Cleaning
After the grout has fully cured (usually after 72 hours), apply a sealer to protect the grout and tiles from stains. Finally, clean the tiles with a mild soap and water solution to remove any remaining grout haze.
Enjoy Your Updated Fireplace
With a little time and effort, you've transformed your brick fireplace into a stunning focal point. Enjoy your updated space and the knowledge that you've added value to your home with a DIY project well done.
