Step 1: Prepare the Space
Take Off Baseboards and Old Floors
First, take off any baseboards and old floors to show the subfloor. This gives a clean, flat area for your tile.
Use a pry bar to gently take off the baseboards without hurting the walls. If you’re changing laminate or vinyl, cut them into smaller pieces and clean all glue. For old tile, use a hammer and chisel or floor scraper to remove tiles and mortar.
Clean the Subfloor Well
Sweep and vacuum the subfloor to remove all dust and dirt. A clean surface helps the mortar stick well and keeps the floor looking good.
Check for Damage or Moisture
Look at the subfloor for cracks, holes, or bumps. Use a level to find dips or high spots.
- Cracks or holes: Fill them with a patching compound.
- Bumpy areas: Use a floor leveling compound to make a flat base.
If the floor is concrete, check for moisture with a meter. Too much moisture can ruin tile or grout, so fix any moisture problems first.
Put in Underlayment or Cement Backer Board (if needed)
Depending on your subfloor type:
- Wood subfloors: Put in cement backer board for a stable, water-resistant base.
- Concrete subfloors: Usually don’t need underlayment, but sometimes a crack isolation membrane or waterproofing membrane is good.
Secure backer board panels as the maker says, using the right screws and leaving gaps between panels.
Step 2: Plan Your Tile Layout
Find the Center of the Room and Mark Guidelines
Start by finding the middle of the room. Measure the center of each wall and use chalk to draw lines across the floor. Where the lines meet is where you start laying tiles. This keeps your tile layout even and neat.
Choose Your Tile Layout Pattern
If you’re new to this, it’s easier to use simple patterns:
- Straight Lay (Grid Pattern): Tiles line up with the walls, forming straight rows.
- Diagonal (Diamond Pattern): Tiles are at a 45-degree angle for a more interesting look — a bit harder but doable.
Note: Fancy designs like herringbone or chevron need more skill and are not for beginners.
Dry-Fit Tiles to Check Alignment
Lay some tiles without mortar (this is called dry-fitting). This lets you:
- Check how they line up and the spacing.
- See how tiles fit against walls, cabinets, or doorways.
- Adjust so you don’t end up with tiny tile pieces at the edges.
Spacing and Grout Lines
Put spacers between tiles during dry fitting for even grout lines. Common sizes are 1/8 inch or 3/16 inch, depending on the tiles.
Calculate Tile Quantity (Add 10–15% for Waste)
Measure the room’s size (length × width). Then:
- Multiply the size by 1.10 for simple layouts or 1.15 for diagonal or tricky cuts. This covers cuts, mistakes, and future fixes.
- Order enough tiles for the whole job.
Step 3: Choose Your Installation Method
For most tile flooring projects, especially large ones, thinset mortar is the preferred method for installation. It creates a strong, lasting bond between tiles and the subfloor.
Common Methods:
- Thinset Mortar (Recommended)
This cement-based adhesive is perfect for floor tiles. It supports weight, moisture, and temperature changes well. Both DIYers and professionals choose thinset for its durability and reliability. - Tile Adhesive (Mastic)
Good for small DIY projects or wall tiles in dry places. It’s easier to use but not strong enough for most floor or wet area installations.
Note: For floor tiling, 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 by following the instructions on the package. Use a clean bucket and a mixing paddle connected to a drill to make it smooth without lumps. After mixing, let it sit for a few minutes before mixing again and applying.
Spread the Mortar
With a notched trowel, spread the mortar evenly on a small part of the subfloor. Keep the trowel at a 45-degree angle to make ridges. These ridges help the tile stick well and ensure the tiles are level.
Work in Small Sections
Only cover as much area as you can tile in about 10–15 minutes. This stops the mortar from drying before the tiles are placed.
Pro Tip:
For bigger tiles, apply a thin layer of mortar to the back of each tile for better sticking, especially for tiles larger than 12 inches.
Step 5: Lay the First Tiles
Starting right is key for the whole project.
Start at Your Layout Center
With your chalk lines from planning, begin at the room’s center or a focal point. This makes sure tiles are spread evenly.
Place the First Tile
Put the first tile in the mortar. Press down and twist it a bit to help it stick.
Use Tile Spacers
Put spacers between tiles to keep even gaps for grout, giving a neat finish.
Check for Level
After a few tiles, use a level to make sure the surface is even. Adjust before the mortar dries.
Pro Tip:
Work in small areas so the mortar stays wet while setting tiles!
Step 6: Cutting Tiles to Fit
Accurate cutting is important for a nice, professional look.
Measure and Mark
Use a tape measure to find the size you need for the tile piece. Mark the line clearly with a pencil or wax pencil.
Choose the Right Tool
For straight cuts, use a manual tile cutter.
For curved or intricate 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 avoid dust. Wear safety glasses and gloves for safety.
Pro Tip:
Measure twice before cutting to save material and get a good fit!
Step 7: Install Remaining Tiles and Let Mortar Cure
Start placing tiles from the beginning point, then continue row by row. Use spacers to keep grout lines even. Make sure tiles are level and adjust if needed to avoid uneven surfaces.
Don’t walk on new tiles to keep them in place. Work in small sections so the mortar doesn’t dry out before you finish.
Let the mortar set for at least 24 hours (or follow the manufacturer’s advice) before adding grout. This step is important for a strong and lasting tile floor.
Step 8: Apply Grout
After the mortar is set, you can grout the spaces between tiles:
Mix the Grout
Mix the grout as instructed until it is smooth like peanut butter.Spread Grout with a Float
Use a rubber grout float at a 45° angle to spread grout over the tile. Press hard to fill all the joints.Remove Extra Grout
After filling, use the float at a steep angle to scrape off extra grout from the tiles.Wipe Tiles with a Damp Sponge
Wait 10 to 15 minutes, then gently clean the tiles with a damp sponge. Rinse the sponge often and avoid taking grout out of the joints.Final Buffing
When grout starts to haze (after 30–60 minutes), use a dry microfiber cloth to buff and clear any haze.
Step 9: Clean and Seal the Floor
Remove Grout Haze
Once the grout dries (usually in 24 to 48 hours), a cloudy film will cover the tiles. Use a damp sponge or a special grout haze remover to carefully clean the tiles. Be sure not to touch the grout lines.
Apply Grout Sealer
If the grout maker suggests, apply a grout sealer to keep moisture, stains, and mold away. Use a small brush or a sealer bottle with a roller tip for careful application. Let the sealer fully dry according to the instructions.
Reinstall Baseboards and Transition Strips
After cleaning and drying everything, put back your baseboards and add any needed transition strips between different floors or rooms. This makes your new tile floor look neat and finished.

Pro Tips for a Successful Tile Flooring Installation
Want to achieve professional results in your DIY tile project? Remember these tips:
- Organize your tools and tiles before you begin. Keep them close for easy access.
- Use a good wet saw for clean and precise cuts, especially on porcelain tiles.
- Mix mortar and grout in small amounts. This helps prevent them from drying out too soon.
- Frequently check if tiles are level using a spirit level while laying them.
- Work on small areas at a time. This ensures the mortar doesn’t dry out before tile placement.
- Reduce tile breakage. Cut tiles slowly and wear safety glasses.
Common Mistakes to Avoid When Installing Tile Flooring
Even skilled DIYers can make these frequent mistakes:
- Not leveling the subfloor. An uneven subfloor can lead to cracked tiles and uneven lines.
- Forgetting to use spacers. Inconsistent grout lines can look unprofessional.
- Walking on tiles before the mortar is set. This can misalign the tiles.
- Using incorrect amounts of mortar. Too much or too little can affect adhesion and leveling.
- Ignoring grout haze. If not cleaned promptly, it becomes tough to remove.
