What kinds of countertops should usually be sealed?

Some types of granite and most marble should be sealed to prevent staining. Tile itself does not need to be resealed regularly, but its grout benefits from resealing for water resistance. A quick way to test is to pour a small bit of water on your countertop and see how long it takes to absorb.
