 A. Mix the Grout. Mix the grout by pouring the water in first, and then add the powder, and stir with a margin trowel. Mix to a smooth (like toothpaste) consistency, let sit for twenty five minutes, then mix again. Note: The thickness of your joint will determine if you can use sanded or unsanded grout.
