Step 1: Prepare the Space
Take Out Baseboards and Old Flooring
Begin by taking out baseboards and old flooring to see the subfloor. This gives a smooth, flat area for new flooring.
Use a pry bar to carefully remove baseboards without harming the walls. If changing carpet or laminate, cut them into small pieces and clean off all glue. For old tile, use a hammer and chisel or a scraper to lift and take out tiles and mortar.
Clean the Subfloor Well
Sweep and vacuum the subfloor to get rid of dust, dirt, and debris. A clean area helps the mortar stick well and keeps your floor looking good.
Check for Damage or Wetness
Look for cracks, holes, or uneven spots in the subfloor. Use a level to find dips or bumps.
- Cracks or holes: Fill them with patching compound.
- Uneven areas: Use a leveling compound to make a flat, strong base.
If on concrete, check for moisture with a moisture meter. High moisture can cause problems, so fix any wetness before continuing.
Put Down Underlayment or Cement Board (if needed)
Depending on your subfloor:
- Wood subfloors: Put down cement board for a strong, water-resistant base.
- Concrete subfloors: Usually don’t need underlayment, but sometimes a crack isolation or waterproofing layer is good.
Attach backer board panels as per instructions, using the right screws and leaving gaps between panels.
Step 2: Plan Your Tile Layout
Find the Room’s Center and Mark Lines
Start by finding the room’s exact center. Use a tape measure to locate the midpoint of each wall and snap chalk lines across the floor in both directions. The crossing point will be your starting spot for laying tiles, helping your layout look even and balanced.
Pick a Tile Layout Pattern
For beginners, simple patterns work best:
- Straight Lay (Grid Pattern): Tiles line up square with the walls, forming neat, uniform rows.
- Diagonal (Diamond Pattern): Tiles are set at a 45-degree angle to the walls for a dynamic look — a bit more challenging but doable.
Note: Complex designs like herringbone or chevron need advanced skills and aren’t suggested for first-timers.
Dry-Fit Tiles to Check Fit
Lay a few rows of tiles without mortar (called dry-fitting). This lets you:
- Check alignment and spacing.
- See how tiles meet walls, cabinets, or doors.
- Adjust to avoid thin tile pieces at room edges (which may look awkward and crack easily).
Spacing and Grout Lines
Use spacers between tiles during dry fit to make even grout lines. Common spacer sizes are 1/8 inch or 3/16 inch, based on tile size and style.
Calculate Tile Amount (Add 10–15% for Waste)
Measure the room’s square footage (length × width). Then:
- Multiply the total square footage by 1.10 (for simple layouts) or 1.15 (for diagonal or rooms with lots of cuts) to cover cuts, mistakes, and future repairs.
- Order that many tiles to make sure you have enough for the whole project.
Step 3: Choose Your Installation Method
For most tile floor projects, especially big ones, thinset mortar is the preferred way to install tiles. It creates a strong bond between tiles and the floor.
Common Methods:
- Thinset Mortar (Recommended)
This cement-based glue works well for floor tiles. It can handle weight, moisture, and temperature changes. Many DIYers and pros use thinset because it’s 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 jobs 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 | Standard for tile flooring. Handles moisture, weight, and movement. |
| Tile Adhesive (Mastic) | Small dry areas, wall tiles | ⭐⭐ (Limited) | Easy | Not for floor tiles or wet areas. Quick use but less durable. |
Step 4: Mix Mortar and Apply to Subfloor
Mix the Mortar
First, mix the thinset mortar as the instructions say. Use a clean bucket and a mixing paddle on a drill 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 evenly on a small part of the subfloor. Hold the trowel at a 45-degree angle to make even ridges. These ridges help the tiles stick well and ensure the right depth for a level setup.
Work in Small Sections
Only cover an area you can tile within 10–15 minutes. This stops the mortar from drying out before you set 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 the right way helps with the whole project.
Begin at Your Layout Center Point
Use chalk lines from your plan to start at the room’s center or main point. This keeps tiles evenly spread out.
Set the First Tile
Put the first tile in the mortar. Press hard and twist it a bit to make it stick well.
Use Tile Spacers
Place spacers between tiles to keep even gaps for grout, ensuring a neat finish.
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 stays wet until tiles are set!
Step 6: Cutting Tiles to Fit
Cutting perfectly is important for a nice finish.
Measure and Mark
Use a tape measure to find the size you need. Mark the line clearly with a 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
Make cuts outside or in a well-ventilated area to avoid dust. Wear safety glasses and gloves for safety.
Pro Tip:
Measure twice before cutting to save material and get a perfect fit!
Step 7: Install Remaining Tiles and Let Mortar Cure
Begin by setting the first tiles, then continue placing the rest in rows. Start from your initial point, carefully putting each tile with spacers for even grout lines. Always check that tiles are level and adjust to avoid uneven surfaces.
As you lay tiles, don’t step on newly placed ones to prevent them from moving. Work in small sections to keep the mortar from drying out before tiles are set.
Once all tiles are in place, let the mortar cure for at least 24 hours (or follow the manufacturer’s advice) before grouting. Proper curing is key for a strong and lasting tile floor.
Step 8: Apply Grout
After the mortar has set, start grouting between the tiles:
Mix the Grout
Mix the grout following the package instructions until it is smooth like peanut butter.Spread Grout with a Float
Use a rubber grout float at a 45° angle to spread grout on the tiles. Push down firmly so grout fills the joints.Remove Extra Grout
After filling the joints, use the float at a steeper 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 removing grout from the joints.Buff the Surface
When the grout looks hazy 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
Remove Grout Haze
After grout dries (usually 24 to 48 hours), a light residue will show on the tiles. Use a wet sponge or special grout haze cleaner to softly 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 grout safe from water, stains, and mold. Use a small brush or a sealer bottle with a roller tip for accuracy. Let the sealer dry completely as per the instructions.
Reinstall Baseboards and Transition Strips
When all is clean and dry, put back the baseboards and add any needed transition strips between different floor types or rooms. This gives your new tile floor a neat, professional look.

Pro Tips for a Successful Tile Flooring Installation
Want pro results for your DIY project? Remember these tips:
- Organize tools and materials first. Keep everything close by.
- Use a good wet saw for neat cuts, especially for porcelain.
- Mix small amounts of mortar and grout. This stops them from drying out too soon.
- Check level often with a spirit level as you work.
- Work in small areas. This keeps the mortar from drying out before placing tiles.
- Reduce breakage. Cut tiles slowly and wear safety glasses.
Common Mistakes to Avoid When Installing Flooring
Even experienced DIYers can make these mistakes:
- Skipping subfloor leveling. Uneven floors can crack tiles and cause lines to be uneven.
- Forgetting spacers. Uneven grout lines look unprofessional.
- Walking on tiles before they set. This can move tiles and mess up alignment.
- Using too much or too little mortar. This leads to poor adhesion or uneven tiles.
- Not cleaning grout haze quickly. Waiting too long makes it hard to remove.
