Save Money on Repairs: Learn How to Replace Broken Slate Tiles


Slate tiles are a popular choice for flooring and roofing due to their durability, natural beauty, and longevity. However, like any other material, slate tiles can break or become damaged over time, leading to potential repair costs. Instead of hiring professionals and spending a significant amount of money on repairs, learning how to replace broken slate tiles yourself can save you a substantial sum. In this comprehensive guide, we will walk you through the steps of replacing broken slate tiles, ensuring that your surfaces maintain their charm and integrity without breaking the bank.

Understanding Slate Tiles:

Before you start replacing broken slate tiles, it’s essential to understand the material you’re working with. Slate is a metamorphic rock, which means it has natural variations in color, texture, and thickness. These variations contribute to its unique appeal. When selecting replacement tiles, try to match the new tiles as closely as possible to the existing ones in terms of color and texture. This will help maintain the seamless appearance of your floor or roof.

Tools and Materials:

To replace broken slate tiles, you’ll need a few essential tools and materials:

  1. Safety gear: Safety goggles, gloves, and a dust mask to protect yourself from debris and dust.
  2. Hammer and chisel: For carefully removing broken tiles and the surrounding mortar.
  3. Grout saw: To remove grout and mortar between the tiles.
  4. Replacement slate tiles: Ensure they match the size and thickness of your existing tiles.
  5. Mortar mix: To secure the new tile in place.
  6. Trowel: For applying the mortar mix.
  7. Level: To ensure the replacement tile sits flush with the surrounding tiles.
  8. Sponge and water: For cleaning excess mortar and grout.

Step-by-Step Replacement Process:

Note: Safety should be your priority throughout this process. Wear appropriate safety gear and work cautiously.

Remove the Broken Tile

  1. Safety first: Put on your safety goggles, gloves, and dust mask.
  2. Loosen surrounding tiles: Gently tap the tiles around the broken one with a hammer and chisel to loosen them.
  3. Remove grout: Use a grout saw to carefully remove the grout around the broken tile.
  4. Remove the tile: Once the grout is cleared, use the hammer and chisel to break the broken tile into smaller pieces. Remove the pieces and clean the area thoroughly.

Prepare the Surface

  1. Clean the area: Use a sponge and water to clean the surface, removing any debris or dust.
  2. Check for damage: Inspect the area for any damage or irregularities that need to be addressed before placing the new tile.

Install the Replacement Tile

  1. Apply mortar: Mix the mortar according to the manufacturer’s instructions. Apply a layer of mortar to the back of the replacement tile using a trowel.
  2. Position the tile: Carefully place the replacement tile into the vacant spot, ensuring it aligns perfectly with the surrounding tiles.
  3. Level the tile: Place a level on top of the new tile to ensure it’s flush with the surrounding tiles. Adjust as necessary.
  4. Clean excess mortar: Use a damp sponge to clean any excess mortar around the edges of the new tile.
  5. Let it set: Allow the mortar to set and cure according to the manufacturer’s instructions.

Finish the Job

  1. Grout the tile: Once the mortar is fully set, apply grout between the tiles using a grout float. Wipe off excess grout with a damp sponge.
  2. Clean the tiles: Clean the entire surface with a damp sponge to remove any remaining grout residue.
