Whether you’re renovating your home, repairing damaged tiles, or updating your flooring, knowing how to remove ceramic tile from a concrete floor properly will help you achieve a smooth, debris-free surface.
This guide will walk you through everything you need to know—from preparation and safety precautions to step-by-step tile removal techniques.
Why Remove Ceramic Tile from a Concrete Floor?
Before diving into the removal process, it’s essential to understand why you might need to remove ceramic tiles from a concrete floor. Some common reasons include:
- Outdated Design – If the tile color, pattern, or material is outdated, you may want to replace it with a modern alternative.
- Cracked or Damaged Tiles – Over time, ceramic tiles can crack due to heavy impact, temperature fluctuations, or improper installation.
- Subfloor Repairs – Sometimes, moisture damage or uneven flooring requires tile removal before repairs can be made.
- Switching Flooring Type – If you prefer hardwood, vinyl, or carpet flooring, the ceramic tiles must be removed first.
Regardless of the reason, removing ceramic tiles from concrete takes time, effort, and the right tools.
Tools and Materials You’ll Need
To efficiently remove ceramic tiles from a concrete floor, gather the following essential tools and safety gear:
Essential Tools for Tile Removal

Step-by-Step Guide: How to Remove Ceramic Tile from Concrete Floor
Step 1: Prepare the Work Area
Before starting the tile removal process, prepare the workspace to minimize mess and ensure safety.
- Clear the Room – Remove all furniture, appliances, or fixtures that may obstruct the process.
- Cover Surrounding Areas – Use plastic sheeting or drop cloths to protect nearby walls and surfaces from dust and debris.
- Ensure Proper Ventilation – Open windows and doors to allow airflow and reduce dust accumulation.
- Turn Off Power if Necessary – If working near electrical outlets, turn off power to prevent accidental shocks.
Step 2: Remove Grout Lines
Breaking the bond between tiles by removing grout lines will make the tile removal process easier.
- Use an angle grinder with a diamond blade to cut through grout lines between tiles.
- Alternatively, use a grout saw or rotary tool with a grout removal attachment.
- Work slowly and carefully to avoid damaging the concrete subfloor underneath.
Step 3: Loosen and Remove the First Tile
Starting at a loose or broken tile will make the job easier. If all tiles are intact:
- Use a hammer and chisel – Place the chisel at a 45-degree angle under the edge of a tile and tap it with a hammer.
- Try a putty knife – For thinner tiles, wedge a putty knife underneath and pry upward.
- Break stubborn tiles – If the tile won’t budge, use a hammer to break it into smaller pieces for easier removal.
Once the first tile is removed, accessing the remaining tiles will be much easier.
Step 4: Remove the Remaining Tiles
After removing the first tile, continue prying up the remaining tiles:
- Work in small sections, moving from one tile to the next.
- Use a pry bar or floor scraper to lift tiles off the concrete.
- For stubborn tiles, use a rotary hammer with a chisel attachment to speed up the process.
Tip: If the tiles are adhered with thin-set mortar, they may be harder to remove. Applying a heat gun or warm water can soften the adhesive and make removal easier.
Step 5: Remove Tile Adhesive and Mortar from Concrete
Once all tiles are removed, the next step is to clean the surface by removing thin-set mortar and adhesive.
- Use a floor scraper – Scrape off as much mortar and adhesive as possible.
- For thick mortar layers, use an angle grinder with a diamond grinding wheel.
- Apply warm water or adhesive remover – This can soften stubborn adhesive for easier removal.
- Vacuum dust and debris – Use a shop vacuum to clean up small tile fragments and dust.
Note: If the mortar is difficult to remove manually, renting a floor buffer with a carbide scraper may be necessary.
Step 6: Inspect and Prepare the Concrete Surface
With the tiles and mortar removed, check the condition of the concrete floor:
- Look for cracks, holes, or uneven surfaces.
- Use a self-leveling compound if the floor is uneven or damaged.
- Let the surface dry completely before installing new flooring.
Proper preparation ensures better adhesion for new tiles, vinyl, hardwood, or other flooring options.
Common Challenges and Troubleshooting Tips
1. What If the Tiles Won’t Come Off Easily?
- Use a rotary hammer or power scraper for stubborn tiles.
- Apply heat (via a heat gun or hot water) to loosen adhesive.
2. How Do I Minimize Dust?
- Work in small sections to reduce airborne dust.
- Spray water lightly over the work area to keep dust down.
- Use a shop vacuum frequently.
3. What If There’s a Lot of Leftover Mortar?
- An angle grinder with a diamond blade will grind off hardened mortar.
- A chemical adhesive remover can soften the mortar for easier scraping.
4. Can I Reuse the Ceramic Tiles?
- If removed carefully, some tiles may be salvageable.
- Soak removed tiles in warm water to soften adhesive before cleaning.
Next Steps After Tile Removal
Once all the tiles, mortar, and debris have been cleared, your concrete floor is ready for the next step—whether that’s installing new tiles, staining the concrete, or laying another type of flooring. Proper preparation ensures better adhesion, durability, and a flawless final result.
If you’re planning to install new tiles, be sure to level the surface, use quality thin-set mortar, and follow proper installation guidelines.
