Removing Tiles from the Concrete Floor

Begin tile removal by identifying a loose or cracked tile to create an entry point. Use a putty knife or floor scraper to pry up the tile edges. If tiles are firmly adhered, follow this step-by-step approach:

  1. Score Grout Lines: Use a utility knife or oscillating tool to score along grout lines, loosening the tile edges.
  2. Break Tiles: Position a chisel at the tile center or edge, then tap it gently with a hammer to crack the tile. Avoid heavy strikes that can damage the concrete.
  3. Pry Up Tiles: Insert the putty knife or chisel under the broken tile pieces and lever them up carefully.
  4. Use Power Tools for Stubborn Tiles: For large or difficult areas, a rotary hammer with a chisel attachment can expedite removal. Hold the tool at a low angle and use controlled, short bursts to chip away tiles.

During removal, continuously clean up debris to maintain a clear workspace and prevent slipping hazards. A shop vacuum is effective for removing dust and smaller tile fragments.

Removing Tile Adhesive and Preparing the Concrete Surface

Once the tiles are removed, residual adhesive or mortar often remains bonded to the concrete, which must be removed for a smooth, level surface suitable for new flooring or finishing.

Common methods to remove adhesive include:

  • Mechanical Removal: Use a floor scraper or chisel to chip away the bulk of the adhesive. For more stubborn patches, a grinding tool with a diamond cup wheel attachment can be used cautiously to avoid gouging the concrete.
  • Chemical Adhesive Removers: Apply a commercial adhesive remover according to manufacturer instructions. Allow the product to soften the adhesive, then scrape it away. Ensure adequate ventilation and wear chemical-resistant gloves.
  • Heat Application: A heat gun can soften certain adhesives, making them easier to scrape off, but care must be taken to avoid overheating or damaging the concrete.
Adhesive Removal Method Best For Precautions
Mechanical Scraping/Grinding Thick or cured adhesive layers Wear dust protection; avoid excessive grinding depth
Chemical Removers Thin adhesive films or residues Use in well-ventilated areas; follow product safety guidelines
