Step 1: Prepare the Space
Take Off Baseboards and Old Floors
Begin by taking off any baseboards and old flooring to show the subfloor. This makes a nice, flat surface for your tile.
Use a pry bar to gently remove the baseboards without harming the walls. If changing carpet, laminate, or vinyl, cut them into smaller pieces and get rid of all sticky stuff. For old tiles, use a hammer and chisel or a floor scraper to take out the tiles and mortar.
Clean the Subfloor Well
Sweep and vacuum the subfloor to remove all dust, dirt, and mess. A clean surface helps the mortar stick well and keeps your finished floor smooth.
Check for Damage or Wetness
Look at the subfloor for cracks, holes, or bumpy spots. Use a level to find low or high points.
- Cracks or holes: Fill them with patching stuff.
- Uneven areas: Use a floor leveling mix to make a flat, steady base.
If you are working over concrete, check for wetness with a moisture meter. Too much wetness can ruin tile or grout, so fix any wetness 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 strong, water-safe base.
- Concrete subfloors: Often don’t need underlayment, but a crack barrier or waterproof cover might be suggested sometimes.
Attach backer board panels following the maker’s instructions, using the right screws and leaving proper gaps between panels.
Step 2: Plan Your Tile Layout
Find Room Center and Mark Lines
First, find the room’s center. Use a tape measure to get the middle of each wall and make chalk lines across the floor. The spot where lines meet is your starting point for tiles. This ensures the tile layout is even and looks nice.
Pick Your Tile Pattern
If you’re new to this, choose easy patterns:
- Straight Lay: Tiles are set square to the walls, making neat rows.
- Diagonal: Tiles are set at a 45-degree angle for a more interesting look — a bit harder but doable.
Note: Hard patterns like herringbone or chevron need more skill and aren’t for first-timers.
Try Tiles Without Mortar
Lay out some tiles without mortar, called dry-fitting. This helps you:
- Check if tiles line up right.
- See how tiles fit by walls or doors.
- Adjust so you don’t get small, awkward tiles at the edges.
Tile Spacing and Grout
Put spacers between tiles when dry-fitting for even grout lines. Common spacer sizes are 1/8 inch or 3/16 inch.
Figure Out Tile Amount (Add 10–15% Extra)
Measure the room (length × width). Then:
- Multiply total square footage by 1.10 (for easy layouts) or 1.15 (for diagonal or tricky rooms) to cover cuts, errors, and repairs.
- Order that many tiles to have enough for the job.
Step 3: Choose Your Installation Method
For most tile floor jobs, especially in big areas, thinset mortar is the top way to install. It helps tiles stick well to the floor.
Common Methods:
- Thinset Mortar (Recommended)
This cement-based glue is great for floor tiles. It handles weight, moisture, and temperature changes well. Many DIYers and pros like thinset because it lasts long and works well. - Tile Adhesive (Mastic)
Good for small DIY spots or wall tiles in dry places. It’s easier to use but not strong enough for most floors or wet areas.
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 places like bathrooms and kitchens, large areas | ⭐⭐⭐⭐⭐ (Excellent) | Moderate | The usual choice for tile flooring. Works well with moisture, weight, and movement. |
| Tile Adhesive (Mastic) | Small dry places, wall tiles | ⭐⭐ (Limited) | Easy | Not good for floor tiles or wet places. Quicker to put on but doesn’t last as long. |
Step 4: Mix Mortar and Apply to Subfloor
Mix the Mortar
Start by mixing the thinset mortar as shown on the package. Use a clean bucket and a drill with a mixing paddle to make it smooth without any 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 area of the floor. Hold the trowel at a 45-degree angle to create even ridges. These ridges help the tile stick well and stay level.
Work in Small Sections
Only cover as much area as you can tile in 10–15 minutes. This prevents the mortar from drying before you lay the tiles.
Pro Tip:
Apply a thin layer of mortar on the back of larger tiles for better adhesion, especially if the tiles are over 12 inches.
Step 5: Lay the First Tiles
Starting right helps the project go well.
Begin at Your Layout Center Point
Use your chalk lines to start from the room’s center or main point. This helps tiles spread evenly.
Set the First Tile
Place the first tile into the mortar. Press firmly and twist it a bit to ensure it sticks well.
Use Tile Spacers
Place spacers between tiles to keep gaps even for grout. This makes it look neat and professional.
Check for Level
After laying some tiles, use a level to ensure the surface is flat. Adjust if needed before the mortar dries.
Pro Tip:
Work in small sections so the mortar stays wet until you place the tiles!
Step 6: Cutting Tiles to Fit
Cutting tiles correctly is key for a nice finish.
Measure and Mark
Use a tape measure to find the size of the tile you need. Mark the cut line with a pencil or wax pencil.
Pick 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 well-ventilated place to avoid dust. Wear safety glasses and gloves for protection.
Pro Tip:
Measure twice before cutting to prevent waste and ensure a perfect fit!
Step 7: Install Remaining Tiles and Let Mortar Cure
Begin by setting the first tiles, then lay the rest one row at a time. Start from your starting point and use spacers to keep grout lines even. Regularly check to ensure tiles are level, adjusting if necessary to avoid uneven spots.
While installing, avoid stepping on new tiles to prevent movement. Work in small sections to stop the mortar from drying before tile placement.
After all tiles are set, let the mortar cure for at least 24 hours (or follow the manufacturer’s directions) before grouting. Proper curing is essential for a strong and long-lasting tile floor.
Step 8: Apply Grout
Once the mortar is dry, you can grout the tile joints:
Mix the Grout
Follow the directions to mix the grout until it’s smooth, like peanut butter.Spread Grout Using a Float
Hold a rubber grout float at a 45° angle to spread grout on the tiles. Press hard to fill all joints.Remove Excess Grout
After filling, use the float at a steep angle to scrape off extra grout from the tiles.Clean the Tiles with a Damp Sponge
Wait 10 to 15 minutes, then gently wipe the tiles with a damp sponge. Rinse the sponge often and be careful not to remove grout from the joints.Final Buffing
When grout starts to haze on the tiles (after 30–60 minutes), use a dry microfiber cloth to buff the surface and clear any haze.
Step 9: Clean and Seal the Floor
Clean Grout Haze
After grout dries (usually 24 to 48 hours), you might see a hazy film on the tiles. Gently wipe the tiles with a damp sponge or grout haze remover. Avoid touching the grout lines.
Use Grout Sealer
If recommended, apply grout sealer to protect against moisture, stains, and mold. Use a small brush or a sealer bottle with a roller tip for precision. Follow the instructions to let the sealer cure completely.
Reattach Baseboards and Transition Strips
When everything is clean and dry, reattach your baseboards and add transition strips between different floors or rooms as needed. This gives your new tile floor a tidy, professional appearance.

Pro Tips for a Successful Tile Flooring Installation
Want success with your DIY tile project? Remember these tips:
- Save time by preparing tools and tiles first. Keep them within easy reach.
- Use a good wet saw for neat cuts, especially on porcelain tiles.
- Mix small batches of mortar and grout. This prevents them from drying too fast.
- Check for level often using a spirit level as you place tiles.
- Work in small sections. This stops 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 common errors:
- Skipping subfloor leveling. Uneven subfloors can lead to cracked tiles and crooked lines.
- Forgetting spacers. Uneven grout lines look unprofessional.
- Walking on tiles before the mortar sets. This can shift tiles and ruin alignment.
- Using the wrong amount of mortar. This results in poor adhesion or uneven tiles.
- Not cleaning grout haze quickly. If left too long, it becomes difficult to remove.
