How to check if your grout is sealed

If you are unsure if your grout, or the tiles themselves, are sealed or not, do a quick "spill test." Take a teaspoon of clean water and dribble it in the center of one of the tiles. If it sinks into the tile, you're dealing with unsealed tiles. If it beads up and evaporates, your tiles are sealed. Repeat this test on the grout. Once you know what you're dealing with, "to seal, or not to seal -that is the question."
