QUESTION:

i bought a carrara marble tile, white with grey; i wanted to create a marble top table so i poured silicone caulking on it and glued to a plastic top table. i left the table backwards for a couple of hours, when i turn it around i realized there were darkish spots inside the marble, almost like dark wet spots in the shape i used to poured the caulk... t is evident that the caulk went thru the marble... will this stains go away? it is because it's wet? will it dry p inside the marble or i just ruined my marble top table?

ANSWER:

Yes, your conclusion is correct. The caulking soaked through the marble and stained the surface.

Since the caulk has completely saturated the marble and is coming from underneath, there's really no way to get the stain "out" like you normally can when something has stained marble surface.

You could try using the procedures for cleaning marble stains found in the Removing Manual Stains Manual and you may get lucky.

You'll be able to remove or diminish staining at the surface, but the problem is that the source of the stain is still there and most likely will continue to leach through to the surface creating a stain again.

The procedure for cleaning marble stains is cheap and easy to do, so worth a shot.
