In this tutorial, we learn how to install a ceramic tile floor. Before installing, you need to prepare a solid base. First, you want to take off the trim, then calculate the area of the room. Prepare the floor by inspecting low or high spots. You will want to apply mortar, then set the backer boards into place. Screw these into place, then finish covering the floor with seam tape. Apply mortar over these then let dry. Now, you can start laying your tile onto the top of this! Once you are finished, you will be ready to use your tile and enjoy the new look of your floors!
