Slate Floor Restoration Sandstone and Slate Floor Cleaning in Delhi NCR
Sandstone and slate are porous, layered stones with an uneven surface that traps dust in exactly the places a mop cannot reach. Hosing them down pushes water into the layers and makes it worse. 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.
- Free inspection of porosity and surface condition
- Masking of walls, skirting and fittings

We show you this on a test patch before quoting the full job, so the result you see at handover is the result you were promised.
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.
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.

Slate Floor Restoration - common questions
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.
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.
Can the floor look exactly new again?
On sound stone with surface wear, yes. Where damage has gone deeper, such as acid burns or stains soaked through the slab, the result is a major improvement rather than perfection, and we tell you which one to expect before starting.
Why do some floors come back brighter than others?
Stone type and previous care. White and hard marbles take a higher gloss; softer or previously acid-washed floors top out lower. Consistent cleaning products are what keep the difference from widening.
Do you guarantee the same result on every surface?
No, and no honest contractor should. A mixed floor gets one uniform gloss level chosen after testing each surface, which sometimes means a satin finish rather than mirror.
