hone-finished black granite

Just built new house with blk. honed granite counter tops in kitchen. Looks like workman already stained it. How do I clean surface? Is there a way to seal these counters and keep them dull (not glossy)? Help.

 

Dear Emilyn:

It's the usual story with hone-finished black “granite”… L

There are indeed different opinions on black honed “granite” surfaces, but there is a unanimous consensus about the fact that it presents maintenance issues.

The problem with honed black granite is that it is not, well … black any more! Most black stones are but an optical illusion: they become black only when highly polished, or when wet. (See the back of your slab to see the real color of your stone!) As you take gloss off the stone surface (and honing does just that) you lose depth of color and the stone turns gray; but when you wet it ... here it is black again! As you spill oily liquids, or you simply touch the stone surface with your fingers (perspiration), you're going to have all sorts of dark surface stains that are a terrible eyesore. Please notice that I said, surface stains, not imbedded stains. In fact, you can clean those stains off (though with lots of labor), while if they were imbedded you would have to poultice them out. If you apply an impregnator/sealer to the stone you will not solve your problem one bit: in fact the sealer will only prevent liquids from being absorbed by the stone (which in the cas e of black honed granite is an unlikely event to begin with), not the staining of its surface.

Any solution?

Well, yes: you have to give up the gray!

If you apply a good-quality stone color enhancer to your countertop instead of an impregnating sealer (a good-quality stone color-enhancer like MB-6 is also an impregnator/sealer) it will turn it permanently black, while preserving the hone finish. In that way, the surface-staining problem would be minimi z ed.

Let's just hope that your fabricator, in their “infinite wisdom,” did not apply an impregnator/sealer to your stone: this would have to be stripped (not an easy feat!), or else the color/enhancer wouldn't stand a chance to work properly.

Of course, now you have to get rid of the surface soiling that you have and to do htat you will have to use a heavy-duty alkaline cleaner rated “for natural stone” like MB-2.

And don't you forget that in order to upkeep your stone and the color enhancer, your best bet is to use good-quality specialty products for stone.
