Transforming a bland wall into a striking feature is easier than you think with slate stone. This natural, durable, and timeless material adds an elegant touch to any space. If you're ready to embark on this DIY project, here's a comprehensive guide on how to install slate stone on a wall, ensuring your project is not only beautiful but also structurally sound.
Before you start, ensure you have the right tools and materials. You'll need slate tiles, thinset mortar, a trowel, a notched trowel, a rubber grout float, a rubber grout finish float, a grout sealer, a level, a tape measure, safety glasses, and gloves. Also, consider the wall's condition - it should be clean, dry, and free of any cracks or damage.
Preparation and Planning
Installing slate stone requires careful planning and preparation. Start by determining the pattern you want to use. Common patterns include straight stack bond, running bond, and herringbone. Once you've decided, sketch a layout on paper, including the location of electrical outlets and switches.
Measure the wall to determine how many tiles you'll need. Slate tiles come in various sizes, so ensure you're ordering the correct amount. Also, consider buying an extra 10-15% for waste and cuts. Slate is a natural material, so tiles may vary slightly in size and thickness.
Installing the Slate Stone
Before you start installing, ensure the wall is clean and free of any debris. If the wall is painted, lightly score it with a utility knife to help the thinset mortar adhere better.
Applying Thinset Mortar
Mix the thinset mortar according to the manufacturer's instructions. Using a notched trowel, spread the mortar onto the wall, holding the trowel at a 45-degree angle. The notches should face the wall. Then, use the straight edge of the trowel to spread the mortar, creating grooves.
Next, hold the trowel at a 90-degree angle and scrape off excess mortar. This will leave ridges of mortar on the trowel. Press the trowel firmly against the wall, holding it at a 45-degree angle, and spread the mortar evenly. This technique is called "combing" and helps create a strong bond between the mortar and the slate tiles.
Installing the Slate Tiles
Starting from the bottom left corner, press the first tile firmly into the mortar. Use a level to ensure it's straight and plumb. Continue installing tiles in your chosen pattern, using spacers to maintain even grout lines. If you encounter an electrical outlet or switch, use a tile cutter to create a hole that fits around it.
As you install each tile, use a rubber grout float to press it firmly into the mortar. This helps create a strong bond and ensures the tile is level. If you're using a large format tile, you may need to use a level to ensure it's straight and level.
Finishing the Installation

Once all the tiles are installed, let the mortar set for at least 24 hours. Then, mix the grout according to the manufacturer's instructions. Using a rubber grout float, spread the grout over the tiles, holding the float at a 45-degree angle. Force the grout into the joints, ensuring they're completely filled.
Cleaning and Sealing
After the grout has set for about 15 minutes, use a rubber grout finish float to remove excess grout from the surface of the tiles. Be careful not to remove grout from the joints. Let the grout set for another 15-30 minutes, then use a damp sponge to clean the tiles.
Once the grout has set for about 72 hours, apply a grout sealer to protect it from stains and moisture. Follow the manufacturer's instructions for application and drying times. After the sealer has dried, your slate stone installation is complete!
Installing slate stone on a wall is a rewarding project that adds value and beauty to your home. With careful planning and execution, you can achieve professional-looking results. So, go ahead, transform that blank wall into a stunning feature that reflects your unique style. Happy tiling!
