Nano Coating for Marble Floors

Nano coating is a thin, penetrating sealer applied after polishing. Its particles line the stone pores and repel oil and water, so spills sit on the surface long enough to be wiped instead of soaking in. It is a stain barrier, not a shine product and not a scratch guard.

What it protects against

• Coffee, tea, oil and food spills on kitchen counters and dining-table marble
• Water marks and hard-water rings
• Everyday dirt sitting in pores, which is what makes a floor look grey

What it does not do

It does not stop scratches (no coating does), does not restore lost gloss, and does not make marble waterproof for hours. A spill left overnight on nano-coated marble can still stain, because vapour passes slowly through the coating.

Application

1. Polish the stone first - a sealer locks in whatever finish is beneath it
2. Clean and dry fully; moisture stops the coating bonding
3. Apply in thin coats, spreading evenly, and wipe off excess before it sets
4. Allow 4 to 6 hours before water contact

Maintenance and lifespan

On a home floor, expect 2 to 4 years. On kitchen counters or commercial surfaces, 12 to 24 months. Re-application is a light process: clean, dry, coat. Harsh acid cleaners strip the coating, which is why the same cleaners also kill the polish underneath.

Cost

Nano coating is normally priced as an add-on after polishing - a small per-sq.ft charge on top of the polish, or quoted per counter top. Doing it over a dull floor is money wasted, because the dullness stays sealed in.

Questions

Is nano coating the same as crystallization?
No. Crystallization builds gloss on the surface; nano coating fills pores to resist staining.

Can I use phenyl afterwards?
Use a pH-neutral cleaner. Phenyl and acids strip both the coating and the polish.

Does it change the look of the stone?
No visible film or colour change when applied correctly.
