Step 1: Prepare the Space
Take Off Baseboards and Old Flooring
Begin by removing baseboards and old flooring to see the subfloor. This makes a flat, clean area for laying tiles.
Use a pry bar to gently remove baseboards without harming the walls. If taking out carpet, laminate, or vinyl, cut into smaller pieces and get rid of all glue. For old tiles, use a hammer and chisel or a floor scraper to take out tiles and mortar.
Clean the Subfloor Well
Sweep and vacuum the subfloor to remove dust, dirt, and bits. A clean area helps the mortar stick well and keeps the finished floor smooth.
Look for Damage or Moisture
Check the subfloor for cracks, holes, or uneven spots. Use a level to find any dips or high spots.
- Cracks or holes: Fill them with a patching mix.
- Uneven spots: Use a floor leveling mix to make a flat, steady base.
If working over concrete, check for moisture with a moisture meter. High moisture can cause tiles or grout to fail, so fix any moisture issues before continuing.
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-resistant base.
- Concrete subfloors: Usually don’t need underlayment, but a crack isolation or waterproofing layer might be suggested sometimes.
Attach backer board panels as the manufacturer says, using the right screws and leaving gaps between panels.
Step 2: Plan Your Tile Layout
Find the Room Center and Mark Lines
Start by finding the room’s center. Measure the middle of each wall and draw chalk lines across the floor. The crossing point is where you start laying tiles to make the layout look even.
Pick Your Tile Layout
For beginners, use simple patterns:
- Straight Lay (Grid Pattern): Tiles line up with walls for neat rows.
- Diagonal (Diamond Pattern): Tiles set at a 45-degree angle for a stylish look—more challenging but doable.
Note: Complex designs need more skill and aren’t suggested for first-timers.
Dry-Fit Tiles for Alignment
Lay some tiles without mortar (dry-fitting) to:
- Check alignment and spacing.
- See tile fit by walls, cabinets, or doors.
- Adjust to avoid small tile pieces at edges, which can look odd and break easily.
Use Spacers for Grout Lines
Put spacers between tiles during dry fit for even grout lines. Common sizes are 1/8 inch or 3/16 inch, based on tile size and style.
Calculate Tile Amount (Add 10–15% for Waste)
Find the room’s square footage (length × width), then:
- Multiply the total by 1.10 (for simple layouts) or 1.15 (for diagonal or many cuts) to cover cuts, errors, and repairs.
- Order this amount to have enough for the whole project.
Step 3: Choose Your Installation Method
For most tile floor projects, especially big ones, thinset mortar is the best way to install tiles. It makes a strong bond between 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. Most people use thinset because it is strong and reliable. - Tile Adhesive (Mastic)
Good for small DIY areas or wall tiles in dry places. It’s easy 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 well. |
| Tile Adhesive (Mastic) | Small dry areas, wall tiles | ⭐⭐ (Limited) | Easy | Not good for floor tiles or wet places. It’s quicker to apply but not as strong. |
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 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 evenly spread the mortar over a small part of the subfloor. Hold the trowel at a 45-degree angle to make even ridges. These help the tile stick well and keep the right depth for a flat installation.
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 you set the tiles.
Pro Tip:
For bigger tiles, put a thin layer of mortar on the back to help them stick better, especially if they’re over 12 inches.
Step 5: Lay the First Tiles
Starting right will make the whole project better.
Start at Your Layout Center Point
Use chalk lines from your plan and begin at the room’s center or main spot. This makes sure tiles are spread out evenly.
Place the First Tile
Put the first tile in the mortar. Press down hard and twist it a bit to help it stick.
Use Tile Spacers
Put spacers between each tile to keep gaps even 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. Fix it as needed before the mortar dries.
Pro Tip:
Work in small areas so the mortar doesn’t dry before the tiles are in place!
Step 6: Cutting Tiles to Fit
Cutting correctly is important for a neat, professional finish.
Measure and Mark
Use a tape measure to find out 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 cut outside or in a place with good air flow to reduce dust. Wear safety glasses and gloves for safety.
Pro Tip:
Measure twice before cutting to avoid mistakes 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 initial spot and place each tile with care, using spacers to keep grout lines even. Check regularly to ensure tiles are level, adjusting if needed to avoid uneven spots.
While working, don’t step on new tiles to prevent them from moving. Work in small areas so the mortar doesn’t dry before tiles are in place.
Once all tiles are laid, let the mortar cure for at least 24 hours (or follow the manufacturer’s advice) before grouting. Proper curing is crucial for a strong and lasting tile floor.
Step 8: Apply Grout
After the mortar is dry, you can grout between the tiles:
Mix the Grout
Follow the instructions to mix the grout until it is smooth like peanut butter.Spread Grout with a Float
Hold a rubber grout float at a 45° angle to spread grout over the tiles. Press firmly so grout fills all the joints.Remove Extra Grout
After filling the joints, hold the float at a steep angle and scrape away extra grout from the tiles.Clean Tiles with a Damp Sponge
Wait 10 to 15 minutes, then gently wipe the tiles with a damp sponge. Rinse the sponge often and do not remove grout from the joints.Final Buffing
When grout starts to haze on the tile (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
After the grout is dry (usually 24 to 48 hours), a hazy layer will show up on the tiles. Use a damp sponge or a grout haze remover 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 to be precise. Let the sealer fully dry as per the product 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 neat and complete.
