How to Install a Tile Floor

Step 1: Prepare the surface

1. Make sure your surface is clean, dry, and debris-free. Patch and repair any uneven or damaged areas.

2. Remove any moldings or appliances that may interfere with the tile installation.

3. Check doorjambs to ensure you have enough clearance to open and close doors once the tile is installed. Note: If you’re working with a concrete or cement substrate, it’s best to apply an anti-fracture membrane before installing the tile. This membrane is available in paste, sheet, or liquid form — the liquid form is the easiest to apply.

Step 2: Lay the tile

1. Determine the center point of each of the four walls, and draw two chalk lines that intersect in the middle of the room — this is where you’ll place your first tile.

2. Starting in the middle of the room, dry-fit a row of tiles along the chalk lines in each direction, forming a cross shape. Take note of where to cut the end tiles so they fit against the walls. For large rooms, consider dividing the room into smaller squares or grids, then working within each square.

3. It’s important to leave a movement or expansion joint around the perimeter of the room, where the tiles meet the walls. This space should be no less than ¼ inch. Do not grout this space. For rooms larger than 20 feet long — and for rooms in direct sunlight all day — break up the space with an expansion joint approximately every 10 feet. Note: If you’re working with ungauged stone tile — tile that varies in thickness and texture and that hasn’t been machine-altered — you may notice slight variations in height between two adjacent tiles. If the variation is noticeable, mark the shorter tile with chalk, so you can make up the difference by applying additional adhesive.

Step 3: Apply the adhesive (thin-set, mortar)

1. Read the manufacturer’s instructions completely, and mix your adhesive in a bucket accordingly. You’ll need to mix small amounts of adhesive as you go. A good general rule — mix only the amount you’ll use in 30 minutes.

2. Generously apply the adhesive to the substrate for the first row of tiles. Take a big scoop of it with your bucket trowel, and apply it. First, spread it out with the smooth side of your notched trowel. Get it as close to the chalk line as you can, without going outside of it. You do, however, want to spread it out beyond the area of the first row of tiles into the area where the next row will be.

3. Next, turn your trowel around so you’re using its notched side. Rake it through the adhesive to create grooves, which create suction and secure the tiles firmly in place.

Step 4: Cut tiles as needed

You can use different methods to cut your tiles, depending on the type of tiles you have and the types of cuts you need to make. The most common tools for cutting tiles include the following:

• Manual tile cutter: Best for making straight cuts in porcelain or ceramic tile.

• Tile nippers: Best for making curved cuts in porcelain or ceramic tile, particularly if you have just a few tiles to cut.

• Wet saw: Best choice for cutting stone tile.

• Jigsaw: A wet saw alternative, best for making cuts in stone tile, particularly if you’re making just a few cuts. You’ll need to outfit the saw with the correct blade, however.

Step 5: Set the tile

1. Starting in the center of the room, lay your tiles, working with one grid at a time. The number of tiles in the grid will depend on the size of your tiles. Press each tile firmly into place. Note: If you marked any uneven tiles in step 2, remember to apply extra adhesive to even it out.

2. Remove any excess adhesive with a putty knife and/or a damp sponge.

3. Tap each tile in the grid firmly with a rubber mallet or wood block.

4. Move to the next grid.

5. Once the entire tile floor is set, allow it to sit for 24 hours before moving to the grouting step.

Step 6: Grout the joints

1. Ensure the floor is dry and clean, with no adhesive anywhere on the tiles. Note: If you’re working with a porous tile, such as natural stone, now’s the time to apply a sealer. Allow the sealer to dry before grouting, per the sealer manufacturer’s instructions. If you’re working with porcelain or ceramic tile, move to step 2.

2. Mix the grout per the manufacturer’s instructions. Like the adhesive, mix only what you’ll use in about 30 minutes.

3. Work on a small grid at a time, similar to the tile-setting process. The largest area you’ll want to grout at a time is approximately 3 feet by 3 feet.

4. Spread the grout onto the tile surface, using a trowel float. Holding the float at a 45-degree angle, work the grout into the tile joints as you move the trowel across the tile. Move the float diagonally across the joints to ensure the best coverage. Scrape off any excess grout from the surface of the tile with your float.

5. Let the grout sit for 15 to 20 minutes, until it has set slightly. Then, clean any remaining grout from the tiles with a dampened sponge, and smooth the joints. Change your water as needed.

6. Once the grout is set, there will be a “haze” or film over the tiles. Buff the surface of the tile with a clean cloth to remove it. The best bet for this job would be an old terry-cloth towel.

7. Wait approximately 72 hours before walking on the floor, or per the grout manufacturer’s instructions.

That’s it! You just installed a tile floor.
