Everything You’ll Need

Step 1: Prepare the Space

Take Away Baseboards and Old Flooring

Begin by taking out any baseboards and old flooring to see the subfloor. This makes a smooth surface for putting down tile.

Use a pry bar to gently remove the baseboards without damaging the walls. If changing carpet, laminate, or vinyl, cut them into smaller pieces and get rid of all glue left behind. For old tile, use a hammer and chisel or floor scraper to take off tiles and mortar.

Clean the Subfloor Well

Sweep and vacuum the subfloor to remove all dust, dirt, and debris. A clean surface helps the mortar stick well and avoids flaws in your finished floor.

Check for Damage or Wetness

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

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

Put Down Underlayment or Cement Backer Board (if needed)

Depending on your subfloor type:

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

Attach backer board panels as per manufacturer instructions, using the right screws and leaving gaps between panels.

Step 2: Plan Your Tile Layout

Find the Center of the Room and Mark Guidelines

Start by finding the middle of the room. Measure each wall’s midpoint, then make chalk lines on the floor. The point where the lines meet is where you start laying tiles. This helps make the tile pattern even and balanced.

Choose Your Tile Layout Pattern

If you’re new, try simple patterns:

Straight Lay (Grid Pattern): Tiles line up with the walls, making neat rows.
Diagonal (Diamond Pattern): Tiles are set at a 45-degree angle for a lively look — a bit harder but doable.

Note: Hard patterns like herringbone or chevron need more skill and are not good for beginners.

Dry-Fit Tiles to Check Alignment

Put down some tiles without mortar (called dry-fitting). This helps you:

Check if they line up right.
See how tiles meet walls, cabinets, or doors.
Change things to stop thin pieces at the edges, which look bad and might break.

Spacing and Grout Lines

Use spacers between tiles when dry-fitting to make even grout lines. Common spacer sizes are 1/8 inch or 3/16 inch, based on the tile size and style.

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

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

Multiply the area by 1.10 for basic layouts or 1.15 for diagonal layouts to cover cuts and future fixes.
Order this amount of tile to make sure you have enough for the job.

Step 3: Choose Your Installation Method

For most tile projects, especially big ones, thinset mortar is best. 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, water, and temperature changes well. Most people use thinset for its durability.
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 choice.

Tile Adhesive (Mastic)	Small dry spots, wall tiles	⭐⭐ (Limited)	Easy	Not for floor tiles or wet areas. Quick to apply but less durable.

Step 4: Mix Mortar and Apply to Subfloor

Mix the Mortar
First, mix the thinset mortar as the maker says. Use a clean bucket and a drill with a mixing paddle to make it smooth and without lumps. Let it sit for a few minutes, then mix again before you use it.

Spread the Mortar
With a notched trowel, spread the mortar evenly over a small part of the floor. Hold the trowel at a 45-degree angle to make even ridges. These ridges help the tile stick well and ensure the right depth for a level install.

Work in Small Sections
Cover only as much area as you can tile in 10–15 minutes. This stops the mortar from drying before the tiles are placed.

Pro Tip:
Put a thin layer of mortar on the back of large tiles (back-butter) for better sticking, especially for tiles over 12 inches.

Step 5: Lay the First Tiles

Starting right will make the whole project better.

Start at Center Point
Use chalk lines from your plan. Begin at the room’s center or main spot. This makes tiles spread out evenly.

Place First Tile
Put the first tile on the mortar. Press hard and twist a bit to make it stick.

Use Tile Spacers
Put spacers between tiles to keep gaps even for grout. This makes a neat finish.

Check Level
After some tiles, use a level to make sure it’s even. Fix it before mortar dries.

Pro Tip:
Work in small parts so mortar stays wet until tiles are set!

Step 6: Cutting Tiles to Fit

Cutting correctly is important for a nice finish.

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

Choose the Right Tool

For straight cuts, a manual tile cutter is good.
For curved or intricate cuts, use a wet saw or an angle grinder with a diamond blade.

Cut in a Safe Area
Make cuts outside or in a space with good airflow to avoid dust. Wear safety glasses and gloves for safety.

Pro Tip:
Measure twice before cutting to save material and make sure it fits!

Step 7: Install Remaining Tiles and Let Mortar Cure

After setting the first tiles, keep placing the rest in rows. Start from your first spot, placing each tile with spacers to keep grout lines even. Check often to ensure tiles are level and adjust if needed to avoid bumps.

As you lay tiles, don’t step on the new ones to avoid moving them. Work in small areas so the mortar doesn’t dry before the tiles are set.

Once all tiles are in place, let the mortar cure for at least 24 hours (or follow the maker’s advice) before grouting. Proper curing is key for a strong, lasting tile floor.

Step 8: Apply Grout

After the mortar is dry, grout the spaces between the tiles:

Mix the Grout
Mix the grout as per the instructions until it is smooth like peanut butter.
Spread Grout Using a Float
Hold a rubber grout float at a 45° angle and spread the grout over the tiles. Press firmly 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 10-15 minutes, then gently clean the tile with a damp sponge. Rinse often and avoid taking grout from the joints.
Final Buffing
When the grout hazes the tile (after 30–60 minutes), use a dry microfiber cloth to buff the surface and clear the haze.

Step 9: Clean and Seal the Floor

Clean Grout Haze
After grout dries (usually in 24 to 48 hours), you might see a haze on the tiles. Use a damp sponge or a special cleaner to gently wipe the tiles. Be careful with the grout lines.

Seal Grout
If suggested by the grout maker, apply a sealer to keep grout safe from moisture, stains, and mold. Use a small brush or a bottle with a roller for accuracy. Let the sealer dry fully as per the instructions.

Put Back Baseboards and Strips
After cleaning and drying, put back your baseboards and add any needed strips between different floors or rooms. This makes your tile floor look neat and finished.

Pro Tips for a Successful Tile Flooring Installation

Want pro results for your DIY tile work? Remember these tips:

Save time by setting up tools and tiles first. Put tiles and tools close by.
Use a good wet saw for clean cuts, especially on porcelain tiles.
Mix small amounts of mortar and grout. This stops them from drying too soon.
Check level often with a spirit level while placing tiles.
Work in small areas. This keeps mortar from drying before tiles are set.
Reduce breakage. Cut tiles slowly and always wear safety glasses.

Common Mistakes to Avoid When Installing Tile Flooring

Even skilled DIYers can make these mistakes:

Not leveling the subfloor. Uneven subfloors cause cracked tiles and crooked lines.
Not using spacers. Uneven grout lines look unprofessional.
Walking on tiles before mortar sets. This shifts tiles and messes up alignment.
Using too much or too little mortar. It causes poor adhesion or uneven tiles.
Not cleaning grout haze soon. Leaving it too long makes it tough to remove.
