What if I get a sealer that lasts a number of years on my granite countertop?

In addition to my previous question, if I seal my granite countertop once with a high quality sealer, should I still re-seal it?  How can I tell if my stone needs re-sealing?

Stay on top of the situation no matter what. If you put a good size round bead of water on your countertop, you should walk away for 15 or 20 minutes, and then check out that bead. If the stone color has changed underneath it or if the bead has flattened, your stone is indeed absorbing liquid. We sell imported Fila brand sealers to the general public for them to do so.
