When it comes to black marble, Negro Marquina is one of the most common stone.
But black marble is one of the most difficult to polish species of marble.
We have developed an effective system that allows us to restore black marble
to its original luster.

This is a picture of Negro Marquina countertop in a five-star hotel.


A customer poured wine or sparkling water and left stain.
Marble and granite countertops are gorgeous but they are porous and
will soak in liquids that can leave stains.
Many types of liquids and sauces can leave their mark including fruit juices,
wine, coffee, tea, water, vinegar, vegetable and olive oils, ketchup etc.,
it’s important to wipe up spills as they happen.

How to Restore
Begin with Micro Polish 4, then polish up with NCA 800, 1500, 3000, 5000
and finish with 8000.
