Perpetual Remodeling Syndrome: Laying Ceramic Tile Floors

by Kelly Smith

Perpetual Remodeling Syndrome (PRS) is brought to you every Thursday by Kelly Smith, who is hopelessly afflicted with this home-altering ailment. Remodeling can be a never-ending and contagious illness, so read on, at your own risk. Don't say we didn't warn you.

For the past few years I've been involved in what I have come to call PRS (Perpetual Remodel Syndrome). Ahh, the joys of home ownership. Since I do enjoy doing home improvement, I feel it's a blessing that my subdivision has no home owner's association. I know the argument; it keeps the standards up. But at least here, there's only one tacky house out of a few hundred.

That being said, today's topic is laying interior ceramic tile floors.Tools for the Project

• Wet saw
• Scraper
• Notched trowel
• Tile spacers
• Electric drill
• Ribbon mixer
• Utility knife
• Claw hammer
• Small pry bar
• Knee pads (Trust me!)
• Chalk line
• Tape Measure
• Rubber mallet
• Grout float and sponge
  

Preparing the Sub-floor

We wanted ceramic tile in the living room but wanted to keep the carpet until the kid could navigate without falling down. I found that the easiest way to remove the carpet was to pull it off the tack strips, cut it into 5' wide strips, roll them up, and use plastic tape to secure them. Then, I did the same with the padding. Next, use the claw hammer and pry bar to take up the tack strip. If there are any drywall compound splatters on the slab from the initial construction, scrape them up.

Now, to get the slab clean, don't sweep; the dust that has sifted through the carpet is very fine and will go airborne. Use a shop-vac. Eyeball the slab carefully. Minor imperfections are alright but if you have major ones, skim them with thinset.

Do Your Tile Layout

Find the center of the room in both directions and snap chalk lines. Visualize this; the chalk lines will look like a big plus sign with the intersection being in the exact center of the room. These are your "control lines." Be sure that your control lines are perpendicular. Use the 3-4-5 method and adjust as needed.

Now it's simply a matter of measuring back to find your border tiles (taking the grout line spacing into consideration). Once you have the border tile size, snap chalk lines so you'll know where to start laying tile. The lines will be parallel to the control lines so the borders might vary in size a bit as you go down the wall. Don't do all four sides of the room; you only need two walls (intersecting in the corner you'll be starting out of). Leave an exit; don't be like the guy that painted himself into a corner!
Mix the Mortar and Lay the Tile

I used mortar on my floor but there are other adhesives out there as well. Your choice. Spread the mortar or adhesive with the trowel evenly and begin laying the tile using the spacers. I like to lay about two rows of four full tiles on one chalk line and then cut and lay the borders. Then I do the same for the other line. Seat each tile by lightly rapping it with a rubber mallet.

Remember to spread the mortar slightly beyond where the tile will lay so there's no void. Voids cause tiles to crack at some time in your future, drawing displeasure from your spousal unit and casting a shadow of doubt over your impressive DIY skills. Don't go there.

All done? Clean up your tools and have an adult beverage of your choice.

Time to Grout!

Grouting is the fun part. I let the mortar dry for twenty four hours first. Mix the grout using the ribbon mixer again. I know you can buy it premixed, but that's cost-prohibitive for all but the smallest of projects. Start grouting where you started laying the tile if that worked well for you. Arm yourself with the sponge in a bucket of water.

First scoop some grout onto the float and work it in between the tiles (removing the spacers as you go). Then grab your sponge, wring it out, and start wiping the grout off the tile surface with a light touch, and forming the concave shape typical to grout lines. As the tiles dry off, you'll see a glaze on them. Don't worry about that now; you'll wipe it off with cheesecloth later.

Finally, after a day or so after the grout's dry, come back and apply a high-quality grout sealer. Other than nailing up the baseboard, your work here is done. As before, clean up your tools and enjoy an adult beverage. You've earned it!
