sealing granite

Hi,

We had a Granite (http://tanbrown.org) kitchen Counter (http://GialloFiorito.com) installed last week, and (http://maplered.com) the installers said that they sealed it.  However, we have noticed a lot of absorption of liquids into the Granite (http://tanbrown.org) .  I was under the assumption that if it was sealed, liquid would bead rather than be absorbed.  We’ve had no luck with getting answers from the Granite (http://tanbrown.org) contractors, so I’m hoping that you have some advice.  If they did seal it, could I damage the Granite (http://tanbrown.org) in any way by sealing it again?  Or will it actually still absorb liquid, even if it’s sealed?

Thanks,

Becky
