Step 1: Prepare the Space
Take Out Baseboards and Old Flooring
First, take off any baseboards and old flooring to show the subfloor. This gives you a clean, flat area for putting down tiles.
Use a pry bar to gently remove the baseboards without hurting the walls. If you’re changing carpet, laminate, or vinyl, cut them into smaller parts and clear away all glue. For old tiles, use a hammer and chisel or a floor scraper to lift and take out the tiles and mortar.
Clean the Subfloor Well
Sweep and vacuum the subfloor to get rid of all dust, dirt, and trash. A clean surface helps the mortar stick right and stops problems in your finished floor.
Check for Damage or Moisture
Look over the subfloor for cracks, holes, or uneven spots. Use a level to find dips or high points.
- Cracks or holes: Fill them with a patching compound.
- Uneven areas: Use a floor leveling compound to make a flat, stable base.
If you’re working over concrete, use a moisture meter to check for moisture. High moisture can cause tiles or grout to fail, so fix any moisture problems first.
Put Down 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 sometimes a crack isolation membrane or waterproofing membrane is suggested.
Secure backer board panels following manufacturer instructions, use the right screws, and leave proper gaps between panels.
Step 2: Plan Your Tile Layout
Find the Middle of the Room and Draw Guidelines
Start by finding the room’s center. Use a tape measure to find the midpoint of each wall, then snap chalk lines on the floor. The lines crossing is where you start laying tiles. This makes sure the tile layout is balanced.
Pick Your Tile Layout Pattern
For beginners, simple patterns are best:
- Straight Lay (Grid Pattern): Tiles are square to the walls, forming neat rows.
- Diagonal (Diamond Pattern): Tiles are at a 45-degree angle to the walls for a dynamic look—slightly harder but doable.
Note: Complex designs like herringbone or chevron need advanced skill and aren’t recommended for first-timers.
Try Tiles Without Mortar to Check Fit
Lay out tiles without mortar (known as dry-fitting) to:
- Check alignment and spacing.
- See how tiles meet walls or doorways.
- Adjust to avoid thin tile pieces at edges (which can look bad and crack easily).
Set Spacing and Grout Lines
Use spacers between tiles during dry fit for even grout lines. Common spacer sizes are 1/8 inch or 3/16 inch, depending on the tile.
Figure Out Tile Amount (Add 10–15% for Waste)
Measure the room’s square feet (length × width). Then:
- Multiply the square footage by 1.10 (for easy layouts) or 1.15 (for diagonal or rooms with many cuts) to cover cuts, mistakes, and future fixes.
- Order enough tile for the whole project.
Step 3: Choose Your Installation Method
For most tile floor jobs, especially big ones, thinset mortar is the main method used. It makes sure the tiles stick well to the subfloor.
Common Methods:
- Thinset Mortar (Recommended)
This cement-based glue works best for floor tiles. It handles weight, water, and temperature changes well. Many DIYers and pros choose thinset for its strength and dependability. - 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 top (and safest) pick.
| Installation Method | Best For | Strength & Durability | DIY Friendliness | Notes |
|---|---|---|---|---|
| Thinset Mortar | Floor tiles, wet areas (bathrooms, kitchens), large spaces | ⭐⭐⭐⭐⭐ (Excellent) | Moderate | Standard choice for tile floors. Handles water, weight, and movement well. |
| Tile Adhesive (Mastic) | Small dry areas, wall tiles | ⭐⭐ (Limited) | Easy | Not good for floor tiles or wet areas. Quick to apply but less strong. |
Step 4: Mix Mortar and Apply to Subfloor
Mix the Mortar
First, mix the thinset mortar following the directions on the package. 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 you use it.
Spread the Mortar
With a notched trowel, 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 keep the right depth for a flat installation.
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 you place the tiles.
Pro Tip:
For bigger tiles, apply a thin layer of mortar to the back of the tile for better sticking, especially for tiles over 12 inches.
Step 5: Lay the First Tiles
Starting right makes the whole project better.
Begin at Your Layout Center Point
Use chalk lines from your plan to start at the room’s center or focus spot. This makes sure tiles are spread out evenly.
Set the First Tile
Put the first tile into the mortar. Press hard and twist it a bit to help it stick.
Use Tile Spacers
Put spacers between tiles to keep even gaps for grout. This gives a neat, professional look.
Check for Level
After placing some tiles, use a level to make sure the surface is flat. Adjust if needed before the mortar hardens.
Pro Tip:
Work in small areas so the mortar doesn’t dry before you finish setting the tiles!
Step 6: Cutting Tiles to Fit
Precise cutting is important for a neat, professional look.
Measure and Mark
Use a tape measure to find the size of the tile piece you need. Mark the line to cut 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 make cuts outside or in a well-ventilated place to avoid dust. Wear safety glasses and gloves to stay safe.
Pro Tip:
Check your measurements twice before cutting to avoid mistakes and get a perfect fit!
Step 7: Install Remaining Tiles and Let Mortar Cure
Start laying the first tiles and then continue placing the rest, one row at a time. Begin from your starting point, using spacers to keep grout lines even. Always check that tiles are level and adjust if needed to avoid uneven areas.
Avoid stepping on new tiles to keep them from moving. Work in small sections so the mortar stays wet until tiles are placed.
Once all tiles are in place, let the mortar cure for at least 24 hours (or follow the manufacturer’s advice) before adding grout. Proper curing is key for a strong and long-lasting tile floor.
Step 8: Apply Grout
When the mortar is dry, it’s time to fill the spaces between the tiles:
Mix the Grout
Follow the instructions to mix the grout until it is smooth like peanut butter.Spread Grout Using a Float
Use a rubber grout float at a 45° angle to spread the grout over the tiles. Press hard to fill all the spaces.Remove Extra Grout
After filling the spaces, hold the float at a steep angle and scrape off extra grout from the tiles.Clean the Tiles with a Damp Sponge
Wait 10 to 15 minutes, then use a damp sponge to gently clean the tiles. Rinse the sponge a lot and don’t remove grout from the spaces.Final Buffing
When the grout starts to haze on the tiles (after 30–60 minutes), use a dry microfiber cloth to buff and remove any haze.
Step 9: Clean and Seal the Floor
Remove Grout Haze
Once the grout is dry (usually 24 to 48 hours), a hazy film may show up on the tiles. Use a damp sponge or a special grout haze remover to gently wipe the tiles. Be careful not to touch the grout lines.
Apply Grout Sealer
If the grout maker suggests it, put on a grout sealer to protect it from water, stains, and mold. Use a small brush or a bottle with a roller tip for careful application. Let the sealer dry completely as per the product’s instructions.
Reinstall Baseboards and Transition Strips
When everything is clean and dry, put back your baseboards and add any needed transition strips between different floors or rooms. This makes your new tile floor look complete and professional.

Pro Tips for a Successful Tile Flooring Installation
Want professional results from your DIY tile project? Remember these tips:
- Save time by organizing tools and tiles before starting. Keep tiles and tools close by.
- Use a good wet saw for clean cuts, especially with porcelain tiles.
- Mix small amounts of mortar and grout. This stops them from drying out too soon.
- Check for level often with a spirit level as you place tiles.
- Work in small areas. This stops the mortar from drying too fast.
- Reduce breakage. Cut tiles slowly and wear safety glasses.
Common Mistakes to Avoid When Installing Tile Flooring
Even skilled DIYers can make these mistakes:
- Skipping subfloor leveling. Uneven floors can cause cracked tiles and crooked lines.
- Forgetting spacers. Uneven grout lines look unprofessional.
- Walking on tiles before the mortar sets. This can move tiles and mess up the layout.
- Using too much or too little mortar. This can lead to bad adhesion or uneven tiles.
- Not cleaning grout haze quickly. Leaving it too long can make it very hard to clean.
