Everything You’ll Need

Step 1: Prepare the Space

Remove Baseboards and Old Floors

Start by taking off the baseboards and old floor to check the subfloor. This makes a smooth area for tiling.

Use a pry bar to carefully remove the baseboards without marking the walls. Cut laminate or vinyl into small parts and remove any glue. For old tile, use a hammer and chisel or a floor scraper to remove tiles and mortar.

Clean the Subfloor Properly

Sweep and vacuum the subfloor to remove all dust and dirt. A clean surface helps the mortar adhere well and improves the floor’s appearance.

Inspect for Damage or Moisture

Check the subfloor for any cracks, holes, or uneven areas. Use a level to find dips or bumps.

  • Cracks or holes: Patch them with a compound.

  • Uneven spots: Use a leveling compound for a flat base.
    If it’s concrete, check for moisture with a meter. Fix any wetness as it can cause tile or grout problems.

Install Underlayment or Cement Board (if needed)

Depending on the subfloor type:

  • Wood subfloors: Install cement backer board for a stable, water-resistant base.

  • Concrete subfloors: Usually don’t need underlayment, but a crack isolation or waterproof membrane might be advised.

Secure backer board panels according to the manufacturer’s instructions, using the correct screws and leaving gaps between panels.

Step 2: Plan Your Tile Layout

Find Center of Room and Set Lines

First, find the center of the room. Measure to get the middle of each wall, then draw chalk lines on the floor. The crossing point is where you begin placing tiles. This helps keep the tile layout even.

Choose Tile Pattern

For beginners, simple patterns are best:

  • Straight Lay (Grid Pattern): Tiles are set in straight lines along the walls.

  • Diagonal (Diamond Pattern): Tiles are placed at a 45-degree angle for a more dynamic look, a bit harder but possible.

Note: Complicated designs need more skill and are not for beginners.

Dry-Fit Tiles to Align

Place some tiles without mortar (dry-fitting). It lets you:

  • Check how tiles line up and the spaces between them.

  • See tile placement near walls, cabinets, or doors.

  • Adjust to avoid thin tile strips at edges that might break.

Tile Spacing and Grout Lines

Use spacers between tiles during dry-fitting for even grout lines. Common sizes are 1/8 inch or 3/16 inch.

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

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

  • Multiply the total size by 1.10 (for simple patterns) or 1.15 (for diagonal or many cuts) to cover cuts, mistakes, and future repairs.

  • Order that tile amount to finish your project.

Step 3: Choose Your Installation Method

For most tile floors, especially big ones, thinset mortar is the best way to install. It helps the tiles stick firmly to the floor.

Common Methods:

  • Thinset Mortar (Recommended)
    This glue is great for floor tiles. It holds up against weight, water, and temperature changes. Both DIYers and pros like thinset because it is durable and strong.

  • Tile Adhesive (Mastic)
    Good for small DIY areas or wall tiles in dry locations. It’s easy to use but not strong for most floors or wet areas.

Note: For floor tiles, thinset is usually the best and safest choice.

Step 4: Mix Mortar and Apply to Subfloor

Mix the Mortar
Start by mixing the thinset mortar as instructed on the package. Use a clean bucket and a drill with a mixing paddle to make it smooth and lump-free. Let it rest for a short time, then mix again before using.

Spread the Mortar
Use a notched trowel to spread the mortar evenly over a small area of the floor. Hold the trowel at a 45-degree angle to form even ridges. These ridges help the tile stick properly and maintain the right level.

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

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

Step 5: Lay the First Tiles

Starting right helps the whole project go well.

Begin at the Center
Use chalk lines to start at the room’s center. This ensures tiles are placed evenly.

Place the First Tile
Put the first tile in the mortar. Press down and twist a bit so it sticks well.

Use Tile Spacers
Place spacers between tiles for even gaps. This makes a tidy finish.

Check Level
After a few tiles, use a level to make sure the surface is flat. Adjust if needed before mortar dries.

Tip:
Work in small areas to prevent the mortar from drying too fast!

Step 6: Cutting Tiles to Fit

Accurate tile cutting is key for a clean look.

Measure and Mark
Use a tape to measure the tile size you need. Mark the cut line with a pencil.

Select the Right Tool

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

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

Cut in a Safe Spot
Cut outside or in an airy area to avoid dust. Wear safety glasses and gloves for protection.

Pro Tip:
Measure twice to avoid mistakes and ensure a perfect fit!

Step 7: Install Remaining Tiles and Let Mortar Cure

Start by putting down the first tiles, then lay each tile one row at a time. Begin where you planned and use spacers to keep grout lines straight. Check often to make sure tiles are level and adjust to prevent bumpy surfaces.

As you lay tiles, don’t step on the new ones to stop them from moving. Work in small areas that you can handle so the glue doesn’t dry before you finish placing the tiles.

After all tiles are placed, let the glue set for at least 24 hours (or follow what the maker suggests) before grouting. Letting it set right is important for a strong and long-lasting tile floor.

Step 8: Apply Grout

After the mortar dries, grout the gaps between the tiles:

  1. Mix the Grout
    Follow the package instructions to mix the grout until it’s like creamy peanut butter.

  2. Spread Grout Using a Float
    Use a rubber float at a 45° angle to apply grout over the tiles, pressing firmly to fill gaps.

  3. Remove Excess Grout
    Once filled, tilt the float steeply and scrape away extra grout from the tiles.

  4. Clean the Tiles with a Damp Sponge
    After 10 to 15 minutes, gently clean tiles with a damp sponge. Rinse often and keep grout intact.

  5. Final Buffing
    When a haze forms on the grout (30–60 minutes later), use a dry microfiber cloth to polish the tiles and remove the haze.

Step 9: Clean and Seal the Floor

Clean Grout Haze
After grout dries (usually 1 to 2 days), a haze may appear on tiles. Clean the tiles gently with a damp sponge or grout haze remover, avoiding grout lines.

Seal the Grout
If suggested, apply a grout sealer to protect from moisture, stains, and mold. Use a small brush or roller tip bottle for careful application. Allow the sealer to dry completely as instructed.

Put Back Baseboards and Strips
Once clean and dry, reinstall baseboards and add transition strips between different floors or rooms. This makes the tile floor appear neat and professional.

Pro Tips for a Successful Tile Flooring Installation

Want your DIY tile project to turn out great? Remember these tips:

  • Save time by preparing tools and tiles first. Keep them nearby.

  • Use a quality wet saw for clean cuts, especially with porcelain tiles.

  • Mix small batches of mortar and grout. This prevents them from drying too quickly.

  • Check the level often using a spirit level when laying tiles.

  • Work in small areas. This stops the mortar from drying before placing tiles.

  • Reduce breakage. Cut tiles slowly and wear safety glasses.

Avoid These Mistakes When Installing Tile Flooring

Even experts can make these common mistakes:

  1. Not leveling the subfloor. Uneven floors can crack tiles and ruin lines.

  2. Not using spacers. This can make grout lines appear messy.

  3. Walking on tiles too soon. This can shift tiles and mess up alignment.

  4. Using too much or too little mortar. This affects how well tiles stick or sit.

  5. Not cleaning grout haze quickly. Waiting makes it harder to remove.
