Step 1: Prepare the Space
Take Off Baseboards and Old Flooring
First, remove the baseboards and old flooring to see the subfloor. This prepares a smooth area for tile installation.
Use a pry bar carefully to take off baseboards without breaking the walls. For carpet, laminate, or vinyl, cut them into smaller pieces and clean any sticky residue. For old tiles, use a hammer and chisel or floor scraper to remove tiles and mortar.
Clean the Subfloor Well
Sweep and vacuum the subfloor to get rid of dust, dirt, and debris. A clean surface helps the mortar stick better and keeps your finished floor smooth.
Check for Damage or Wetness
Look at the subfloor for cracks, holes, or uneven spots. Use a level to find dips or high areas.
- Cracks or holes: Fill them with a patching compound.
- Uneven areas: Use a floor leveling compound to make a flat, stable base.
If working over concrete, test for moisture using a moisture meter. Fix any moisture problems before continuing.
Put in Underlayment or Cement Backer Board (if needed)
Depending on your subfloor:
- Wood subfloors: Install cement backer board for a stable, water-resistant base.
- Concrete subfloors: Usually don’t need underlayment, but a crack isolation membrane or waterproofing may be suggested sometimes.
Follow the manufacturer’s instructions to secure backer board panels, using the right screws and leaving proper gaps between panels.
Step 2: Plan Your Tile Layout
Find the Center of the Room and Mark Guidelines
First, find the middle of the room. Measure the middle of each wall and snap chalk lines across the floor. The crossing point is where you’ll start laying tiles. This makes sure your tile design looks even.
Choose Your Tile Layout Pattern
If you’re new to this, use easy patterns:
- Straight Lay (Grid Pattern): Tiles align square with the walls, making neat rows.
- Diagonal (Diamond Pattern): Tiles are placed at a 45-degree angle for a lively look — a bit harder but doable.
Note: Fancy designs like herringbone or chevron need more skill and aren’t for beginners.
Dry-Fit Tiles to Check Alignment
Lay a few rows of tiles without mortar (dry-fitting). This helps you:
- Check the alignment and spacing.
- See how tiles meet walls, cabinets, or doors.
- Adjust to avoid thin tile edges at the room’s ends (they can look bad and break easily).
Spacing and Grout Lines
Use spacers between tiles during dry fit to keep grout lines even. Common spacer sizes are 1/8 inch or 3/16 inch, depending on tile size and style.
Calculate Tile Quantity (Add 10–15% for Waste)
Measure the room’s size (length × width). Then:
- Multiply the total size by 1.10 (for simple layouts) or 1.15 (for diagonal or rooms with many cuts) to cover cuts, mistakes, and future repairs.
- Order this amount of tile to have enough for the whole project.
Step 3: Choose Your Installation Method
For most tile flooring jobs, especially big ones, thinset mortar is the usual method. It makes a strong bond between the tiles and the floor.
Common Methods:
- Thinset Mortar (Recommended)
This cement glue is great for floor tiles. It handles weight, wetness, and temperature changes well. Many DIYers and pros use thinset because it is strong and reliable. - Tile Adhesive (Mastic)
Good for small DIY areas or wall tiles in dry places. It’s easier to use but not strong enough for most floor tiles or wet spots.
Note: For floor tiles, thinset is almost always the best and safest choice.
| Installation Method | Best For | Strength & Durability | DIY Friendliness | Notes |
|---|---|---|---|---|
| Thinset Mortar | Floor tiles, wet places (bathrooms, kitchens), large areas | ⭐⭐⭐⭐⭐ (Excellent) | Moderate | Standard for tile floors. Handles wetness, weight, and movement. |
| Tile Adhesive (Mastic) | Small dry areas, wall tiles | ⭐⭐ (Limited) | Easy | Not good for floor tiles or wet places. Quick to apply but not very strong. |
Step 4: Mix Mortar and Apply to Subfloor
Mix the Mortar
Begin by mixing the thinset mortar as the instructions say. Use a clean bucket and a mixing paddle with a drill to make it smooth without lumps. Let it sit for a few minutes, then mix again before using.
Spread the Mortar
Use a notched trowel to spread the mortar evenly on 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 ensure it’s level.
Work in Small Sections
Cover only as much area as you can tile in about 10–15 minutes. This stops the mortar from drying before placing the tiles.
Pro Tip:
Apply a thin layer of mortar to the back of larger tiles for better sticking, especially for tiles over 12 inches.
Step 5: Lay the First Tiles
Starting right will make the whole project better.
Start at the Center Point
With your chalk lines ready, begin at the center of the room or a key spot. This helps spread tiles evenly.
Place the First Tile
Put the first tile into the mortar. Press down and twist it a little to make it stick well.
Use Tile Spacers
Put spacers between tiles to keep even gaps for grout. This gives a neat and professional look.
Check for Level
After a few tiles, use a level to check the surface is flat. Adjust if needed before the mortar dries.
Pro Tip:
Work in small areas to prevent the mortar from drying too quickly!
Step 6: Cutting Tiles to Fit
Cutting tiles correctly is important for a nice finish.
Measure and Mark
Use a tape measure to find the size of the tile piece you need. Mark the line with a pencil or wax pencil.
Choose the Right Tool
For straight cuts, a manual tile cutter is good.
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 air flow to keep dust away. Wear safety glasses and gloves for safety.
Pro Tip:
Measure twice before cutting to save material and get a great fit!
Step 7: Install Remaining Tiles and Let Mortar Cure
After setting the first tiles, place the rest one row at a time. Start from your initial spot and use spacers to keep even grout lines. Make sure tiles are level and adjust if necessary to keep surfaces smooth.
Avoid stepping on new tiles to stop them from moving. Work in small areas so the mortar doesn’t dry before tiles are laid.
Once all tiles are in place, let the mortar cure for at least 24 hours (or follow the manufacturer’s advice) before adding grout. Good curing is important for a strong and lasting tile floor.
Step 8: Apply Grout
When the mortar is fully set, you can grout the spaces between the tiles:
Mix the Grout
Mix the grout following the package directions until it is smooth like peanut butter.Spread Grout Using a Float
Hold a rubber grout float at a 45° angle to spread the grout over the tiles. Press down to fill all the spaces well.Remove Excess Grout
After filling the spaces, tilt the float steeply and scrape off extra grout from the tiles.Clean the Tiles with a Damp Sponge
Wait 10 to 15 minutes, then gently clean the tiles with a damp sponge. Rinse the sponge often and try not to take grout out of the spaces.Final Buffing
When a haze forms on the tile (after 30–60 minutes), use a dry microfiber cloth to buff and clear away the haze.
Step 9: Clean and Seal the Floor
Remove Grout Haze
After the grout dries (usually 24 to 48 hours), a cloudy film may show up on the tiles. Use a damp sponge or special grout haze remover to gently clean the tiles. Be careful not to mess up the grout lines.
Apply Grout Sealer
If the grout maker suggests it, put on a grout sealer to keep the grout safe from water, stains, and mold. Use a small brush or a sealer bottle with a roller tip for careful application. Let the sealer dry completely as per the instructions.
Reinstall Baseboards and Transition Strips
When everything is clean and dry, put back your baseboards and add any needed transition strips between different floor types or rooms. This makes your new tile floor look neat and professional.

Pro Tips for a Successful Tile Flooring Installation
Want great results from your DIY tile project? Remember these tips:
- Save time by getting tools and tiles ready first. Keep them close by.
- Use a good wet saw for clean cuts, especially on porcelain.
- Mix small amounts 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 parts. This keeps the mortar from drying before tiles are set.
- Reduce breakage. Cut tiles slowly and wear safety glasses.
Common Mistakes to Avoid When Installing Tile Flooring
Even skilled DIYers can make these mistakes:
- Ignoring subfloor leveling. Uneven floors can crack tiles and make lines crooked.
- Not using spacers. Uneven grout lines look unprofessional.
- Walking on tiles before mortar sets. This can move tiles and mess up alignment.
- Using too much or too little mortar. This affects tile adhesion and levelness.
- Not cleaning grout haze quickly. Waiting too long makes it tough to remove.
