Absolute BLack granite streaks/marks |
Article Number: 1426 | Rating: Unrated | Last Updated: Thu, May 15, 2008 at 12:00 AM |
Hello, We recently had absolute black granite coutertops installed in our kitchen. We were informed that they were sealed once installed. On the first day of use, we had glasses and cups with iced water, and bottles on the countertops. Soon after we saw streaks, rings, and light and/or dark marks on the counters which could not be removed by towel drying. Could this be a product of impropoer or non-sealed granite or a potentially dyed granite? Thanks very much,
Dear Adel:
Let's start by sying that black granite can't be technically sealed. Sop forget about the impreoper sealing and all that garbage – end of the debate.
Now let's see what that could be:
BLACK ABSOLUTE GRANITE
Let's start by saying that the only black mercantile granite that has the legal right to be called “Black Absolute” is the one coming from
There used to be three possibilities to explain the problems that you are experiencing, which are here listed in order of probability (the first being the most probable):
In the last couple of years there's been a change in the scenario above. Another possibility has entered the scene:
4.
Certain manufacturers apply some sort of protective wax to the slabs. It is not actual “doctoring,” since there's no alteration to the color of the stone, but
the result is the same as if the slab had been “doctored” with the “shoe-shine.”
Finally, case 3 above is not as rare as it used to be anymore. At least a couple of “Black Absolute Granites” allegedly from
Having said all that, the remedy to the points 1, 2 and 4 is to remove whatever it is that's sitting on the stone surface, by either stripping it chemically by soaking it with a solution of water and phosphoric acid, or mechanically, by rubbing on the stone surface a polishing compound for marble (NOT for granite!) with a little bit of water.
Case 3 is terminal.
From a legal point of view, cases 2 and 3 are full-fledged consumer fraud and could be prosecuted by the law.
All things considered, black granite – which should be considered among the most enjoyable materials as a kitchen countertop – has made it out my own list of recommended stones.
Until the industry will not straighten its act up by becoming serious about the classification of all the different “granites” on the marketplace and dictate strict rules and guidelines about their characteristics and implied guarantees to the consumers, my position is going to be that from now on.
