Granite Floor Restoration: Polishing and Deep Cleaning

Granite is a hard natural stone often chosen for busy floors, but hardness does not mean it is scratch-proof, stain-proof or immune to impact damage. Depending on the stone's condition, options may include deep cleaning, mechanical surface refinement, polishing or suitable sealing.

Why does granite lose its appearance?

Grit and heavy traffic can wear the surface over time. Grout residue, unsuitable cleaners or old maintenance products may also create a dull film. Some granites absorb particular liquids, and chips can occur around edges or after impact despite the stone's generally hard character.

An assessment is needed to tell removable residue from damage in the polished stone itself.

Cleaning versus polishing

Deep cleaning uses a product and method appropriate to the granite and any existing sealer. Where the actual surface has worn, specialist abrasives may be used to improve the finish. Granite is relatively hard and often needs a different process from marble or limestone; equipment and cost can differ accordingly.

Old coatings may need investigation before removal. Grinding or reducing raised tile edges should only be considered after checking the tile thickness, bond and construction.

What about cracks and chips?

Small edge damage may sometimes be repaired with a suitable compatible material, but visual matching is not guaranteed. Cracks associated with movement in the floor require further assessment rather than a cosmetic fill alone.

Does granite need a sealer?

Porosity varies by stone and treatment. Some granite may benefit from an appropriate impregnating sealer; others may not require one. Testing and product compatibility are better guides than an automatic sealing schedule.

Care after restoration

Remove abrasive grit, choose a cleaner appropriate to the stone and finish, and promptly attend to spills. Do not treat a claim of 'scratch-proof' as a reason to ignore furniture protection or maintenance.

A clear photograph in daylight, close-ups of scratches or chips, floor area and location help determine whether cleaning, polishing or repair is likely to be relevant.
