How to Remove Tile Adhesive from Concrete — A Complete DIY Guide
The Problem With Tile Adhesive
After removing floor tiles, you are almost always left with a rough, uneven layer of adhesive stuck to the concrete slab. This needs to be removed before you can lay new flooring, apply epoxy coating, or polish the concrete.
Manual scraping is slow and ineffective for anything larger than a small bathroom. A concrete floor grinder is the right tool for the job.
What You Will Need
Step-by-Step Process
1. Prepare the area
Remove all furniture and sweep the floor. Check for any protruding nails or screws. Fill any deep cracks with floor filler and let it cure before grinding.
2. Set up your dust extraction
Connect your H-Class dust extractor to the grinder before you start. Concrete dust contains silica, a serious respiratory hazard. Dust controls are required under Safe Work Australia regulations.
3. Choose the right disc
For tile adhesive removal, start with a medium-grit diamond disc. Hard epoxy-based glue may need a coarser disc.
4. Start grinding
Begin at one end of the room and work in overlapping passes. Move at a consistent pace — too slow grinds too deep; too fast leaves adhesive behind.
5. Check your progress
After each pass, sweep and inspect. Repeat over stubborn patches.
6. Clean up
Sweep thoroughly and vacuum. The surface is now ready for new flooring, epoxy, or polishing.
