How to Install Ceramic Tile Floor

A true ceramic floor can be a major selling point for any home. Unlike laminates, vinyl or carpeting, ceramic tiles carry a certain artisanal cachet. Part of it is the multi-step process required to lay down such tiles, but part is the simple depth of ceramics’ history. With literally more than ten thousand years of evolution, earthenware may represent the oldest craft known to humankind.

Thankfully you don’t need to spend a fraction of that time on the installation. Most professionals who know how to install a ceramic tile floor agree the most important part is preparation. Once you have your roadmap and each piece cut to fit, the rest takes little more than patience and precision. When you are finished, the results can be literally dazzling, creating an inviting space where before there was little more than solid earth tones.

The first step is to clear the room entirely. This means more than just furniture and knick-knacks – you will literally need to remove everything, including appliances. In the kitchen this means the oven, stove and fridge, and in the bathroom it means the toilet, molding and any pedestal sinks. The idea is to get a completely flat surface that will act as a true floor for all your belongings, now and in the future.

Vinyl makes a poor backing for ceramic tiles, so you will want to cut and remove any plastic flooring such as this. The glue itself should be scraped away as well, and you may even want to break out the sandpaper to ensure you have a truly level surface. In the case of pieces such as molding, be sure to keep track of which piece belongs where so that you can reinstall it in a pinch.

Sheetrock works fine as a substrate for more ceramic tile projects, but bathrooms and kitchens prone to excess moisture will last longer with cementitious ceramic tile backerboards. These inexpensive pieces provide additional protection against moisture and help cushion the tiles so they are less prone to cracking under daily abuse. If concrete or drains are nearby, you may even want to add a moisture layer to ensure the grout isn’t rotted away from the inside.

The next step is measuring. Ceramic tiles look best when they radiate from a central spot, but you also want to be wary of ending up with incredibly thin cuts at the borders of the room. Aim for a location close to the center that still allows for a pleasing layout, and don’t forget to compensate for the separators and grout that will affect the tile distribution.

Laying the tile is the most painstaking part of the process, but it can also be the most satisfying. Use rubber spaces to account for the grout and provide a nice even appearance, and you should see a clean pattern emerge within a few rows. Depending on the thickness of the tile and its uniformity, it may be necessary to leave extra space between each tile for the mastic and grout.

Don’t be afraid to waste tile as you create trim pieces with a wetsaw. If the layout is locked and you are comfortable with the appearance, you can begin mixing the mortar in a bucket. Be sure to mix well and vigorously, as the chemicals involved have a tendency to separate, giving your floor something less than a uniform appearance.

Lift the tiles in bunches and use a trowel to spread the mortar evenly. Press them back into place and remove the rubber spacers. Continue with this process until the entire floor has been laid out according to your plan. Remember: time is of the essence here, as you don’t want the mortar to set before the job is complete!

Your final step is to mix and work the grout into the floor, pressing as hard as you can to fill all the gaps. A grout sponge and some water will be required over the next hour or so to ensure the tiles are clean on their surfaces. Your final step is to caulk the room’s edges and apply a sealant if the manufacturer recommends one. If the tiles are shiny and the grout has set, you can replace everything as it was and enjoy the new room.
