Thus in this case, the sealer is useless and will most likely cause more harm than good. If the sealer is applied to a marble surface that will not absorb it, then a lot of times the sealer will not be completely wiped away and will ultimately evaporate and leave behind the solid resin creating a hazy look that ruins some of the marble's shine.
