ᐅ Terrazzo Restoration (1960s): Removing Tile Adhesive from Stairs & Hallway Inspection
Created on: 6 Jan 2026 20:03

genericHello everyone,
we have purchased a house from the 1960s/70s and discovered a terrazzo staircase beneath the old tiles in the stairwell. I definitely want to preserve it and restore its shine.
I have already carefully removed the tiles by hand. Now I am facing the challenge of removing the stubborn tile adhesive (cement-based).
My current problem: When trying to loosen the adhesive with a hammer and scraper/chisel, small terrazzo particles often chip off. The substrate seems to be more delicate than the adhesive itself.
My questions for the experts:

My current problem: When trying to loosen the adhesive with a hammer and scraper/chisel, small terrazzo particles often chip off. The substrate seems to be more delicate than the adhesive itself.
My questions for the experts:
- What is the gentlest approach for the material? (Sanding instead of chiseling?)
- Which tools would you recommend for the stair treads (especially corners and edges)? (e.g., renovation sander, random orbital sander, multi-tool?)
- What grit should I start with to remove only the adhesive without creating deep grooves in the terrazzo?
- Are there chemical aids (e.g., adhesive remover/soap solution) that really help with old cement-based adhesive?
- Is it worth preserving terrazzo tiles?
- Is restoring the slabs significantly more labor-intensive or "risky"?
- Or is it ultimately more economical/easier to remove and replace them?
I think the idea of preserving an old terrazzo floor is excellent!
For a proper renovation, in addition to the technical aspects, practical experience in grinding terrazzo is absolutely necessary.
When the old courthouse in Trier was completely renovated, I had the honor of being responsible for the floor constructions and restorations there. The original floor on the ground floor was supposed to be removed and replaced with a modern floor covering. My intervention was successful, and a young company from the "new federal states" was awarded the contract for the surface restoration. The floor was ground multiple times (!) using different grades of abrasives and was finally treated and maintained.
If, as in your case, old adhesive residues remain on the terrazzo, please do not attempt to remove the adhesive grooves with aggressive mechanical tools! Ask a specialized company here for a quote, but please do not expect success using rental machines from a general hardware store. Expert knowledge is required!

Good evening!
Thank you for your reply. I am just concerned that if I have a professional company do all this work, it might exceed my budget. Therefore, I would like to do some preliminary work myself to keep costs manageable. By preliminary work, I mean removing the tile adhesive.
