How to Lay a Floor Tile

Floor Tile Installation Technique

Installing your own tile can save you allot of money. The staff a GNH will help you get all of the materials to accomplish the job.

Preparing for the tiles to be installed is the most important part of installing a great tile floor The first step is to install a solid level subfloor, using cement backer boards. If the subfloor is not installed properly, the grout or the tile itself will crack. Lay down the cement board using as many full sheets as possible, and stagger the boards for stability. Cut partial sheets when necessary with the circular saw after measuring and marking them with guides. Secure the cement boards to the floor/subfloor with screws.

Watch the video to layout the tiles properly. Find the midpoint of the floor, then layout the tiles from the center to the walls. Adjust the layout so that the tiles bear the traffic, not the grout lines (straddle the traffic area). Leave a 1/4″ space for the grout using the plastic spacers. Mix the grout to the consistency of peanut butter. Use the notch trowel for tile adhesive (ask GNH what size groove to get). Create ridges of thinset adhesive with the notch trowel, quickly to place the tiles into the adhesive. With a rubber hammer or wood block, gently tap the tiles down into place. Use a level to test the alignment levelness of the tiles. Occasionally wipe the tiles to keep them clean. Let the tiles set for 24 hours.

Before grouting the joints, use stone sealer if you are installing porous slate or marble. Ceramic tiles do not have to be sealed. Mix the grout and put it into the grooves with the grout float and then wipe the excess with a moist rag but do not make it too wet. Finish the grout off with your finger for a smooth and finished look.
