Step-by-Step Process for Removing Tile from Concrete

The removal process involves careful preparation followed by systematic tile extraction and cleanup:

Prepare the workspace by clearing furniture and covering vents or doorways with plastic sheeting to contain dust. Ensure you are wearing all recommended safety gear before beginning.

Begin by testing a small area to determine how firmly the tiles are adhered. This will help you select the appropriate tools and techniques.

Use an angle grinder to score grout lines between tiles if tiles are firmly set, which loosens their hold and prevents large sections from breaking unpredictably.

Start prying tiles up at the scored lines or edges using a chisel and hammer or a floor scraper. For stubborn tiles, employ a rotary hammer with a chisel bit to break the bond.

Once tiles begin to loosen, use a pry bar to lift and remove them carefully. Be cautious to avoid damaging the concrete slab underneath.

After tile removal, scrape off any remaining thinset or adhesive using a floor scraper or a rotary hammer with a flat chisel attachment.

Clean the area thoroughly with a shop vacuum to remove dust and debris.

Methods for Removing Adhesive Residue

Adhesive residue left on the concrete slab can interfere with future flooring installations if not removed properly. Here are common methods used to tackle adhesive removal:
