How do I know if my granite countertop is sealed?

[Mark D.]

I would use the lemon test to determine how absorbent your stone is. Drip a few drops of lemon juice onto your granite. If you see that under the drops of lemon it develops very quickly dark spots, it means that it's a very absorbent stone. If it takes a minute or two to be absorbed, then you're dealing with a better degree of absorbency. Either one should be easily manageable with the application of a good-quality impregnator-type sealer.
If it doesn't absorb into the stone at all, then you have a winner right there! Go for it, and don't bother sealing it.
