Indian Sandstone Restoration Sandstone and Slate Floor Cleaning in Delhi NCR
These stones are cleaned by controlled scrubbing and then protected with an impregnating sealer. Polishing them is usually wrong, because the whole point of the finish is the natural matte texture. Delhi NCR mixes very old housing stock with new high-rise towers, so a single visit can mean Kota stone in one room and Italian marble in the next. We carry pads for both and quote each surface on its own merit.

Keeping the finish after the job is done
| Habit | Why it matters |
|---|---|
| Dry dust mopping | Removes grit before it scratches the surface |
| pH-neutral cleaner only | Acid etches marble and bleach dulls the finish |
| Damp mop, never flooding | Standing water leaves marks and weakens joints |
| Mats at entries | Captures grit where it enters |
| Felt pads under furniture | Stops drag marks on polished surfaces |
- A light maintenance polish every 12-18 months keeps gloss without a full job
- Commercial floors are usually re-polished annually, homes every two years
- Sealer or nano coating, where applied, is refreshed on the schedule we hand over
After-care guidance is handed over in writing: which cleaner to use, how to mop, and what to avoid during the first week. Most repeat problems trace back to cleaning products rather than the work itself.
Every job ends with a walkthrough. You see the gloss reading, the treated patches and the joints before the crew packs up, and the same crew owns any correction needed later.

- No acid on sandstone or limestone

Indian Sandstone Restoration - common questions
Should sandstone be polished?
Usually not. Sandstone reads best with its natural matte finish, and polishing it only makes the surface unevenly reflective. Where a smoother finish is wanted, honing is the right process.
What are the white patches on my sandstone or slate?
Efflorescence, mineral salts pushed to the surface by moisture. It is removed with a pH-neutral treatment, and the underlying damp should be addressed or it returns.
Can slate be sealed outdoors?
Yes, with an impregnating sealer, and it will need re-sealing every twelve to twenty-four months depending on rain and foot traffic.
Is pressure washing safe?
On soft sandstone it is not, because it erodes the surface and drives water into the layers. Controlled low-pressure cleaning with the right brushes is safer.
How often does the floor need a maintenance polish?
Every 12-18 months for homes and every 8-12 months for commercial floors. It is a much smaller job than the original restoration.
Which cleaner should we use?
A pH-neutral stone cleaner with clean water, dried after mopping. Avoid acid, bleach and abrasive powders, which are the main causes of dull and etched floors.
Can maintenance work be done room by room?
Yes. We schedule it in sections so the house stays usable, and it takes a fraction of the time of a full polish.
