Step 1: Choose a Grout Color

Choosing grout colors is just as important as the color of the tiles. Use a grout chart to choose a color that will fit in with your tiles.

Step 2: Mix the Grout

First lay down the rosin paper to protect the counter, taping the seams to the edges of the tile.Then, mix modified grout with water using a paddle mixer. Modified grout has polymers in it that help prevent shrinking and cracking.

Let the grout slake (rest and thicken up) for about 10 minutes and then stir it again until it reaches a peanut butter like consistency.

Step 3: Apply the Grout

Using a float, apply the grout at a 45-degree angle. Make sure to really work the grout in between the spaces.

Tip: You may want to consider using a margin float, which is great for using around edges of the grout.

After letting the grout set for about 15-20 minutes, take a sponge and working at a 45-degree angle to the grout joint, wipe away any excess grout. Try not to pull any grout out of the joint.
