Step 1: Prepare the Space

Take Off Baseboards and Old Flooring

Begin by taking off the baseboards and any old flooring to show the subfloor. This sets a clean, flat area for your tile work.

Use a pry bar to gently remove the baseboards without harming the walls. If changing carpet, laminate, or vinyl, cut them into small pieces and clear all glue. For old tile, use a hammer and chisel or a scraper to pull up and take away the tiles and mortar.

Clean the Subfloor Well

Sweep and vacuum the subfloor to get rid of all dust, dirt, and bits. A clean spot helps the mortar stick right and keeps your final floor smooth.

Check for Damage or Wetness

Look at the subfloor for cracks, holes, or uneven spots. Use a level to find dips or bumps.

  • Cracks or holes: Fill them with a patching compound.
  • Uneven spots: Use a floor leveling compound to make a flat, steady base.
    If working over concrete, check for wetness with a moisture meter. High moisture can cause tile or grout problems, so fix any wetness issues before continuing.

Add Underlayment or Cement Backer Board (if needed)

Depending on your subfloor type:

  • Wood subfloors: Add cement backer board for a stable, water-resistant base.
  • Concrete subfloors: Usually don’t need underlayment, but a crack isolation membrane or waterproofing membrane might be suggested sometimes.

Attach backer board panels following manufacturer directions, using the right screws and leaving proper gaps between panels.

Step 2: Plan Your Tile Layout

Find the Center of the Room and Mark Guidelines

First, find the middle of the room. Measure each wall’s midpoint and draw chalk lines across the floor. The crossing point is where you start laying tiles. This makes sure the tiles are even and look nice.

Choose Your Tile Layout Pattern

For beginners, simple patterns are best:

  • Straight Lay (Grid Pattern): Tiles line up with the walls in neat, even rows.
  • Diagonal (Diamond Pattern): Tiles are placed at a 45-degree angle for a dynamic look — a bit trickier but doable.

Note: Fancy designs like herringbone or chevron need more skill and are not for first-timers.

Dry-Fit Tiles to Check Alignment

Lay out some tiles without mortar (called dry-fitting) to:

  • Check how they line up and the spacing.
  • See how they fit with walls or doorways.
  • Adjust to avoid thin pieces at edges (they may look odd and break easily).

Spacing and Grout Lines

Use spacers between tiles during dry fitting to keep grout lines even. Common sizes are 1/8 inch or 3/16 inch, depending on the tile.

Calculate Tile Quantity (Add 10–15% for Waste)

Measure the room’s area (length × width). Then:

  • Multiply by 1.10 for simple layouts or 1.15 for diagonal or tricky rooms to cover cuts and mistakes.
  • Order this amount to ensure you have enough tiles for the whole project.

Step 3: Choose Your Installation Method

For most tile flooring jobs, especially big ones, thinset mortar is the best way to install tiles. It makes tiles stick well to the floor.

Common Methods:

  • Thinset Mortar (Recommended)
    This adhesive is great for floor tiles. It works well with weight, water, and temperature changes. Many people use thinset for its strength and reliability.
  • Tile Adhesive (Mastic)
    Good for small DIY spaces or wall tiles in dry places. It’s easier to use but not strong enough for most floors or wet places.

Note: When tiling a floor, thinset is usually the best and safest option.

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 get 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 floor. Hold the trowel at 45 degrees to make even ridges. These ridges help tiles stick better and ensure the right level.

Work in Small Sections
Only cover as much as you can tile in 10–15 minutes. This stops the mortar from drying before placing the tiles.

Pro Tip:
For larger tiles, apply a thin layer of mortar on the back for better sticking, especially for tiles over 12 inches.

Step 5: Lay the First Tiles

Starting right will make the whole project go well.

Start at Your Layout Center Point
Use the chalk lines from your planning to 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 hard and twist it a little to help it stick.

Use Tile Spacers
Put spacers between each tile to keep gaps for grout even. This gives a neat, professional look.

Check for Level
After placing some tiles, use a level to make sure the surface is even. Adjust if needed before the mortar dries.

Pro Tip:
Work in small areas so the mortar doesn’t dry out before the tiles are in place!

Step 6: Cutting Tiles to Fit

Accurate cutting is key for a polished, professional-looking finish.

Measure and Mark
Use a tape measure to determine the size of the tile piece you need. Mark the cutting line clearly with a pencil or wax pencil.

Choose the Right Tool

  • For straight cuts, a manual tile cutter works well.

  • For curved or intricate cuts, use a wet saw or an angle grinder with a diamond blade.

Cut in a Safe Area
Always make cuts outdoors or in a well-ventilated space to avoid dust buildup. Wear safety glasses and gloves for protection.

Pro Tip:
Measure twice before cutting to reduce waste and ensure a perfect fit!

Step 7: Install Remaining Tiles and Let Mortar Cure

Once the first tiles are set, continue laying the remaining tiles row by row. Work outward from your starting point, placing each tile carefully with spacers to maintain uniform grout lines. Regularly check that tiles are level and adjust as needed to prevent uneven surfaces.

As you progress, avoid walking on newly set tiles to prevent shifting. Work in manageable sections to ensure the mortar doesn’t dry out before tiles are placed.

After all tiles are installed, allow the mortar to cure for at least 24 hours (or as recommended by the manufacturer) before proceeding to grout. Proper curing is essential for a durable and long-lasting tile floor.

Step 8: Apply Grout

Once the mortar has fully cured, it’s time to grout the joints between the tiles:

  1. Mix the Grout
    Follow the manufacturer’s instructions to mix the grout to a smooth, peanut butter-like consistency.

  2. Spread Grout Using a Float
    Use a rubber grout float held at a 45° angle to spread the grout across the tile surface. Press firmly to ensure the grout fills all the joints completely.

  3. Remove Excess Grout
    After filling the joints, hold the float at a steep angle and scrape away excess grout from the tile surfaces.

  4. Clean the Tiles with a Damp Sponge
    Wait about 10 to 15 minutes, then use a damp sponge to gently wipe the tile surfaces clean. Rinse the sponge frequently and avoid removing grout from the joints.

  5. Final Buffing
    Once the grout begins to haze on the tile (after another 30–60 minutes), use a dry microfiber cloth to buff the surface and remove any remaining haze.

Step 9: Clean and Seal the Floor

Remove Grout Haze
After the grout has dried (usually 24 to 48 hours), a hazy residue will appear on the tile surfaces. Use a damp sponge or specialized grout haze remover to gently clean the tiles. Be careful not to disturb the grout lines.

Apply Grout Sealer
If recommended by the grout manufacturer, apply a grout sealer to protect the grout from moisture, stains, and mold. Use a small applicator brush or a sealer bottle with a roller tip for precision. Allow the sealer to cure fully according to the product instructions.

Reinstall Baseboards and Transition Strips
Once everything is clean and dry, reinstall your baseboards and add any necessary transition strips between different flooring types or rooms. This gives your new tile floor a polished, professional finish.

Pro Tips for a Successful Tile Flooring Installation

Want to get pro-level results from your DIY tile project? Keep these tips in mind:

  • Save time by organizing tools and tiles before starting. Lay out tiles and tools within easy reach.
  • Use a high-quality wet saw for clean, precise cuts — especially for porcelain tiles.
  • Mix small batches of mortar and grout. This prevents drying out before use.
  • Check for level frequently with a spirit level as you lay tiles.
  • Work in small sections. This ensures the mortar doesn’t dry before you place the tiles.
  • Minimize breakage. Always cut tiles slowly and wear safety glasses.

Common Mistakes to Avoid When Installing Tile Flooring

Even experienced DIYers can make these common errors:

  1. Skipping subfloor leveling. An uneven subfloor can cause cracked tiles and uneven lines.
  2. Forgetting spacers. Inconsistent grout lines lead to an unprofessional look.
  3. Walking on tiles before the mortar cures. This can shift tiles and ruin alignment.
  4. Using too much or too little mortar. This can cause poor adhesion or tiles sitting unevenly.
  5. Not cleaning grout haze promptly. Leaving grout haze too long can make it very hard to remove.
