Sealer directions tend to be very similar, however the active ingredients may be very different.
In this case, Daniel's suggestion of a product that would do both materials was accurate. The Countertop Sealer will perform well on grout and granite, but the Grout Sealer is actually formulated to work best on cement-based products ..... it would no doubt function on the granite but the durability and length of life would not be as good as with another sealer such as the Countertop Sealer or the ones Daniel mentioned..........
