1. Identify the stone
Marble and travertine are calcium-based natural stones; terrazzo contains aggregate in a cementitious or resin binder. Concrete has still different properties. Misidentification can lead to unsuitable treatment.
2. Identify the problem
Grit scratches, acid etching, stains, damaged filler, wax and other coatings can look similar at first glance. Cleaning cannot repair all physical damage.
3. Choose the least aggressive suitable method
Cleaning, surface repair, honing and polishing serve different purposes. The correct abrasive sequence depends on the condition and desired finish. Test areas help establish realistic results.
4. Consider practical constraints
Stone thickness, access, edges, dust or slurry, adjoining finishes, timing, safety and slip performance can all influence the project.
5. Discuss ongoing care
Surface treatments vary by material. Sealing may improve resistance to some spills but does not generally prevent acid etching on marble or travertine.
