Step 1: Prepare the Space
Remove Baseboards and Old Flooring
First, take off baseboards and old flooring to see the subfloor. This gives you a clean, flat area for new tile.
Use a pry bar to gently remove baseboards so walls don’t get damaged. If changing carpet, laminate, or vinyl, cut them in small pieces and clear away glue. For old tile, use a hammer and chisel or floor scraper to take out tiles and mortar.
Clean the Subfloor Thoroughly
Sweep and vacuum the subfloor to get rid of dust and dirt. A clean floor helps mortar stick well and keeps your floor smooth.
Inspect for Damage or Moisture
Look for cracks, holes, or uneven spots on the subfloor. Use a level to find dips or bumps.
- Cracks or holes: Fill them with patching compound.
- Uneven areas: Use a floor leveling compound to make a flat base.
If your floor is concrete, check for moisture with a moisture meter. Fix any moisture issues before continuing.
Install Underlayment or Cement Backer Board (if needed)
Depending on your subfloor type:
- Wood subfloors: Put down cement backer board for a stable, water-resistant base.
- Concrete subfloors: Usually don’t need underlayment, but a crack isolation membrane or waterproofing might be useful.
Attach backer board panels as per manufacturer’s instructions, using the right screws and leaving space between panels.
Step 2: Plan Your Tile Layout
Find the Room’s Center and Mark Lines
Start by finding the room’s center. Measure the midpoint of each wall and snap chalk lines across the floor. The crossing point is where you begin laying tiles. This keeps your tile layout balanced.
Pick a Tile Layout Pattern
If you’re new to this, choose simple patterns:
- Straight Lay (Grid Pattern): Tiles line up square with the walls, making neat rows.
- Diagonal (Diamond Pattern): Tiles are set at a 45-degree angle, giving a lively look — a bit harder but doable.
Note: Complex designs like herringbone or chevron need advanced skills and aren’t for beginners.
Dry-Fit Tiles to Check Fit
Place a few rows of tiles without mortar (called dry-fitting). This helps you:
- Check alignment and spacing.
- See how tiles meet walls, cabinets, or doors.
- Adjust to avoid thin tile slivers at edges (which may look odd and crack easily).
Set Spacing and Grout Lines
Use spacers between tiles during dry fit for even grout lines. Common sizes are 1/8 inch or 3/16 inch, based on tile size and style.
Figure Out Tile Amount (Add 10–15% for Waste)
Measure the room’s square footage (length × width). Then:
- Multiply by 1.10 for simple layouts or 1.15 for diagonal or tricky rooms to cover cuts, errors, and repairs.
- Order this amount to ensure enough tile for the project.
Step 3: Choose Your Installation Method
For most tile floor projects, especially big ones, thinset mortar is the best way to install tiles. It makes the tiles stick strongly and last a long time.
Common Methods:
- Thinset Mortar (Recommended)
This is a cement glue that’s great for floor tiles. It can handle weight, water, and temperature changes. Both DIY folks and pros like it for being strong and reliable. - Tile Adhesive (Mastic)
Good for small DIY areas or wall tiles in dry spots. It’s easier to use but not strong enough for most floors or wet places.
Note: For floor tiles, thinset is usually the best and safest option.
| Installation Method | Best For | Strength & Durability | DIY Friendliness | Notes |
|---|---|---|---|---|
| Thinset Mortar | Floor tiles, wet areas (bathrooms, kitchens), large spaces | ⭐⭐⭐⭐⭐ (Excellent) | Moderate | Industry standard for tile flooring. Handles moisture, weight, and movement. |
| Tile Adhesive (Mastic) | Small dry areas, wall tiles | ⭐⭐ (Limited) | Easy | Not recommended for floor tiles or high-moisture areas. Faster application but lower durability. |
Step 4: Mix Mortar and Apply to Subfloor
Mix the Mortar
First, mix the thinset mortar as shown on the package. Use a clean bucket and a drill with a mixing paddle to make it smooth without lumps. Let it sit for a few minutes, then mix again before using.
Spread the Mortar
With a notched trowel, spread the mortar over a small part of the subfloor. Hold the trowel at a 45-degree angle to make even ridges. These ridges help the tile stick well and keep the right depth for a flat installation.
Work in Small Sections
Only cover the amount you can tile in 10–15 minutes. This stops the mortar from drying before the tiles are put down.
Pro Tip:
For bigger tiles, put a thin layer of mortar on the back of the tile (back-butter) to help it stick better, especially if the tiles are over 12 inches.
Step 5: Lay the First Tiles
Starting right will make the whole project go well.
Begin at Your Layout Center Point
Use chalk lines to start at the room’s middle or a main spot. This helps spread tiles evenly.
Set the First Tile
Put the first tile in the mortar. Press hard and twist a bit so it sticks well.
Use Tile Spacers
Put spacers between tiles for even gaps. This gives a neat, nice look.
Check for Level
After some tiles, use a level to make sure it’s flat. Fix if needed before the mortar dries.
Pro Tip:
Work in small parts so the mortar stays wet until the tiles are placed!
Step 6: Cutting Tiles to Fit
Cutting tiles accurately is important for a nice finish.
Measure and Mark
Use a tape measure to find the size you need for the tile. Mark the line with a pencil or wax pencil.
Choose the Right Tool
For straight cuts, use a manual tile cutter.
For curved or detailed cuts, use a wet saw or an angle grinder with a diamond blade.
Cut in a Safe Area
Always cut outside or in a place with good airflow to avoid dust. Wear safety glasses and gloves to stay safe.
Pro Tip:
Measure twice before cutting to save material and get a perfect fit!
Step 7: Install Remaining Tiles and Let Mortar Cure
Start by placing the first tiles, then continue setting tiles one row at a time. Move out from your starting point, using spacers to keep grout lines even. Check often to make sure tiles are level, and make adjustments to avoid uneven surfaces.
As you work, don’t step on new tiles to keep them from moving. Work in small sections so the mortar doesn’t dry before you finish placing the tiles.
Let the mortar cure for at least 24 hours (or follow the manufacturer’s instructions) before grouting. This helps create a strong and durable tile floor.
Step 8: Apply Grout
After the mortar sets, grout the spaces between the tiles:
Mix the Grout
Mix the grout until it’s smooth, like peanut butter, following the instructions.Spread Grout Using a Float
With a rubber grout float at a 45° angle, spread grout over the tiles. Press down to fill all spaces.Remove Excess Grout
Scrape off extra grout with the float held at a steep angle.Clean the Tiles with a Damp Sponge
After 10 to 15 minutes, gently wipe tiles with a damp sponge. Rinse the sponge often, but don’t remove grout from the joints.Final Buffing
When haze appears on the tiles (after 30–60 minutes), use a dry microfiber cloth to buff and clear any haze.
Step 9: Clean and Seal the Floor
Take Off Grout Haze
After the grout dries (about 24 to 48 hours), you might see a haze on the tiles. Use a damp sponge or special grout haze remover to clean the tiles softly. Be careful not to touch the grout lines.
Put On Grout Sealer
If the grout maker suggests it, apply a grout sealer to keep grout safe from water, stains, and mold. Use a small brush or a sealer bottle with a roller tip for accuracy. Let the sealer fully dry as per the instructions.
Put Back Baseboards and Transition Strips
When everything is clean and dry, put your baseboards back and add any needed transition strips between different floor types or rooms. This makes your tile floor look neat and professional.

Pro Tips for a Successful Tile Flooring Installation
Want pro results from your DIY tile project? Keep these tips in mind:
- Save time by organizing tools and tiles first. Place them within easy reach.
- Use a good wet saw for clean cuts, especially on porcelain tiles.
- Mix small batches of mortar and grout. This stops them from drying out too soon.
- Check for level often with a spirit level while laying tiles.
- Work in small sections. This keeps mortar from drying before placing tiles.
- Minimize breakage. Cut tiles slowly and wear safety glasses.
Common Mistakes to Avoid When Installing Tile Flooring
Even experienced DIYers can make these mistakes:
- Skipping subfloor leveling. An uneven subfloor can crack tiles and create uneven lines.
- Forgetting spacers. Inconsistent grout lines look unprofessional.
- Walking on tiles before mortar cures. This can shift tiles and mess up alignment.
- Using too much or too little mortar. This affects adhesion and tile evenness.
- Not cleaning grout haze promptly. Leaving it too long makes it hard to remove.
