Marble Floor Polishing: How It Works, How Long It Takes, and How to Remove Etch Marks

Marble floors are beautiful, and in Florida homes and condos they are everywhere. They are also soft compared to other stones and sensitive to acids, which is why so many marble floors end up dull, scratched or covered in cloudy spots.

The good news is that marble can be polished back to a shine again and again. Here is how it works.

What marble polishing actually is

Real marble polishing is not a product you wipe on. It is a process of refining the surface of the stone itself.

• Grinding (when needed): heavy diamonds flatten lippage between tiles and remove deep scratches.
• Honing: a series of finer and finer diamond pads removes etch marks, light scratches and wear.
• Polishing: very fine diamonds and polishing compounds bring the surface to the level of shine you want, from matte to high gloss.
• Sealing: a penetrating sealer helps the stone resist stains.

Not every floor needs every step. A floor with light dullness may only need polishing. A floor with lippage and deep scratches needs grinding first. We decide after seeing the floor.

How long does marble polishing take?

For a typical home, marble polishing usually takes one to a few days, depending on square footage, how many steps the floor needs, and whether there are repairs. A light polish on a small area can be done in a day. A full grind, hone and polish on a large floor takes longer.

You can usually walk on the floor carefully soon after polishing, but plan to keep furniture off and avoid spills until the sealer has cured. We will give you a schedule with your quote.

What affects the cost of marble polishing

Every floor is different, so we quote after seeing it. The biggest price factors are:

• Square footage, and how many rooms and small areas like bathrooms and closets are included.
• The condition of the floor: light dullness vs. deep scratches, lippage or cracked tiles.
• Whether old wax or coatings have to come off first.
• The finish you want: a honed (matte) finish takes fewer steps than a high polish.
• Access, furniture moving, and building rules in condos.

How to remove etch marks from marble

Etch marks are those dull, lighter spots and rings that show up where something acidic touched the stone: lemon, wine, juice, soda, vinegar, tomato sauce, or many bathroom cleaners. They look like water spots, but they are not stains. The acid has actually eaten a tiny layer of the stone.

Light etching on polished marble

Very light etch marks can sometimes be improved with a marble polishing compound made for etching, used exactly as the label says. Test in a hidden spot first. This works best on small spots on polished (shiny) marble.

Deeper or widespread etching

When etching is deep, covers a large area, or keeps coming back in kitchens and bathrooms, the floor needs professional honing and polishing. This removes the damaged layer and brings the whole floor back to an even finish, so you do not end up with shiny patches next to dull ones.

Keeping polished marble shining

• Dust mop often. Grit is what dulls marble in high-traffic paths.
• Clean with a pH-neutral stone cleaner. No vinegar, bleach, ammonia or "all-purpose" cleaners.
• Use mats at doors and coasters or trays under glasses and bottles.
• Wipe up spills right away, especially anything acidic.
• Check your sealer once or twice a year with a water drop test and reseal when needed.

Frequently Asked Questions

How do you buff marble floors?

Buffing a marble floor that is already in good shape can be done with a floor machine, a white or soft pad, and a stone polish made for marble. If the floor is etched or scratched, buffing alone will not fix it, and it needs honing and polishing with diamonds.

How many days does marble polishing take?

Most homes take one to a few days, depending on size, condition and the finish you want.

What is the best liquid for polishing marble?

For everyday care, a pH-neutral marble cleaner. For light etching, a marble polishing compound made for that purpose. Avoid waxes and "shine" products, which leave a film that dulls and yellows.

Can a dull marble floor be made shiny again?

Yes. Honing and polishing remove the dull, worn layer and restore the shine. Marble can be refinished many times over its life.

Is it better to hone or polish marble?

It is a matter of look and use. A polished finish is shiny and shows the color best. A honed finish is matte, shows etching less, and is less slippery, which some people prefer in kitchens and bathrooms.
