Typically marble finishing is done at the factory when the marble slabs are run through a big machine that grinds down and polishes the marble. It’s more of a topical coating that if enough is applied, you can buff it to a bit of a shine. I have tried telling the developers that perhaps the benchtops haven’t been sealed but they aren’t listening.

The fact that the water and lemon juice spots did not darken tells you that nothing will absorb very easily or at all into the marble, so no use in sealing it.

Of course, if it was the installers error then they should correct it in the manner you choose at no additional cost.

For polished or shiny marble you can use a marble polishing paste, but for a honed marble benchtop you don’t want to “polish” it.

When it begins to dry within 3-5 minutes, re wet the surface with another thin layer of sealant.

If the excess dries on the surface, spray or pour more sealer onto the granite and immediately wipe away. Rinse the surface thoroughly after washing with the soap solutions and dry is a clean towel. Use a clean, dry towel to rub the powder into the stone, or you can use a buffing pad on a low speed power drill. However, as noted above, marble (or nearly any stone) can have a number of different finish types. A shiny polished finish will wear down with foot traffic creating dull trails around the floor.

If your marble or travertine tile floors need refinishing, you’ll want to learn about recrystallization. As noted above, the original finish (no matter what type) is done “at the factory” with machines. Again, a finish can be changed once installed, but that is a demanding job that requires special abrasives, tools and the skill of an experienced stone restoration professional. Although, it could have been etched by using the wrong marble cleaning products, but that’s the only time it ever “needs” marble polishing.

The trick with this product is to keep adding water and rub in a circular motion for several minutes. If you have deep etching its going to take a long time to get it out so you may want to start with something else. I made the big big mistake of spraying an area of my bathroom with a vinegar water solution to get rid of some ants. I almost resigned myself to always needing to have a covering over the center of the table. As the week past, it started to bug me that the mark could still be seen at certain angles. I spent probably 20 minutes of heavy duty rubbing and buffing (over several sessions) and it’s made a nice difference.

A matte or “honed” surface is basically achieved by stopping the process right before the marble polishing step that turns the counter top surface glossy.

But if a marble countertop or tile is honed or tumbled when installed, you’ll have to hire a marble maintenance pro to re-finish and “polish” the surface into a shine.

And you could use this paste for polishing marble that is honed, but you’d likely end up with an uneven finish. Marble everywhere else in the house is not a problem, but a kitchen just gets too much abuse and use and it’s absolutely impossible to keep from etching it. Marble does etch very easily though as your lemon juice test demonstrated, which does make it impractical for kitchen benchtops.

So, if you spill orange juice on the honed marble and wipe it up within 15 seconds, it could still etch the marble leaving a more dull spot. Be sure that the surface is clear of any debris and has been dry for a couple hours prior to sealing. After 5 minutes, wipe the excess sealer off with a clean, dry white terry cloth towel or paper towel. Sand, dirt and grit do the most damage to natural stone surfaces because of their abrasiveness.

This is spread over the stain with a spatula about ¼ to ½ inch thick and left covered over 24 to 48 hours.

Natural stone can be finished with a number of different surface types, styles or looks depending on what is wanted by the buyer. And even though colors are more muted with a hone finish, many stone colors and patterns are more appealing with a honed finish. Also, this specialized product is engineered to work on marble (travertine or limestone too) that was originally polished to a shine.

Likewise, if you use the wrong products for cleaning marble (too acidic or too alkaline) you can destroy the shiny finish over the entire surface making your whole marble countertop or floor “dull”. It will make a honed marble shiny or more shiny, but it is not made to be used by a homeowner to re-finish a large area like a floor or entire countertop.

If it is “dull” or honed, then likely that’s the way it is supposed to be and it doesn’t “need polishing”. Of course, if you’d rather have a shiny polished finish, then you can have a honed surface polished into a shine by a professional, but there is nothing “wrong” with the honed floor. My fabricator had used “bullet proof,” a water based sealer…which clearly wasn’t working. I spent about an hour using this and it did get rid of the lighter etching but the deeper etching still remains.

It takes a bit of trial and error, but the key was to keep the area very wet and keep spreading or finessing out the spot further and further to blend. This led me to the internet, where all kinds of etching removers are online, it was hard for me to decide.

I had splashed cleaning vinegar on my marble sink top and it had etched into the marble leaving alot of marks.

I bought this to address etching on my brand new marble counter tops (see red arrow in photo).
