Step 1: Prepare the Space
Take Off Baseboards and Old Flooring
First, take off the baseboards and old flooring to see the subfloor. This makes a smooth surface for your new floor.
Use a pry bar to gently remove the baseboards without hurting the walls. If changing carpet, laminate, or vinyl, cut them into smaller pieces and clean up any sticky stuff. For old tile, use a hammer and chisel or a scraper to take off the tiles and mortar.
Clean the Subfloor Well
Sweep and vacuum the subfloor to remove dust, dirt, and junk. A clean surface helps the mortar stick well and keeps your new floor looking good.
Check for Damage or Wetness
Look for cracks, holes, or uneven spots on the subfloor. Use a level to find any dips or bumps.
- Cracks or holes: Fill them with a patching mix.
- Uneven spots: Use a floor leveling mix to make a flat, strong base.
If on concrete, check for wetness with a moisture meter. Too much wetness can cause problems, so fix any wetness issues first.
Put Down Underlayment or Cement Backer Board (if needed)
Depending on your subfloor:
- Wood subfloors: Put down cement backer board for a solid, water-safe base.
- Concrete subfloors: Usually don’t need underlayment, but in some cases, a crack isolation membrane or waterproofing membrane is suggested.
Attach backer board panels following the maker’s instructions, using the right screws, and leave gaps between the panels.
Step 2: Plan Your Tile Layout
Find the Center of the Room and Mark Guidelines
Start by finding the room’s center. Measure the middle of each wall and mark lines across the floor. The lines’ crossing point is where you begin placing tiles. This keeps your tile layout balanced.
Choose Your Tile Layout Pattern
For beginners, use simple patterns:
- Straight Lay (Grid Pattern): Tiles are placed square with the walls, forming neat rows.
- Diagonal (Diamond Pattern): Tiles are set at a 45-degree angle to the walls for a lively look — a bit harder but doable.
Note: Designs like herringbone need more skill and aren’t suggested for first-timers.
Dry-Fit Tiles to Check Alignment
Place a few tile rows without mortar (called dry-fitting). This lets you:
- Check how tiles line up and space out.
- See how tiles meet walls or doorways.
- Adjust to avoid thin tile pieces at edges (which can look odd and might crack).
Spacing and Grout Lines
Use spacers between tiles during dry fit to keep grout lines even. Common sizes are 1/8 inch or 3/16 inch, based on tile size and style.
Calculate Tile Quantity (Add 10–15% for Waste)
Find the room’s square footage (length × width). Then:
- Multiply by 1.10 for simple layouts or 1.15 for diagonal or complex rooms to cover cuts and errors.
- Order this tile amount to ensure enough for the project.
Step 3: Choose Your Installation Method
For many tile flooring jobs, especially in big spaces, thinset mortar is often used. It makes tiles stick well to the floor.
Common Methods:
- Thinset Mortar (Recommended)
This type of glue works great for floor tiles. It can handle weight, water, and temperature changes. Both home users and pros pick thinset because it’s strong and lasts a long time. - Tile Adhesive (Mastic)
Best for small DIY areas or wall tiles in dry spots. It’s easier to apply but not strong enough for most floors or wet places.
Note: For floor tiles, thinset is usually the top choice for safety and strength.
| Installation Method | Best For | Strength & Durability | DIY Friendliness | Notes |
|---|---|---|---|---|
| Thinset Mortar | Floor tiles, wet areas (bathrooms, kitchens), large spaces | ⭐⭐⭐⭐⭐ (Excellent) | Moderate | Standard choice for tile floors. Good with water, weight, and movement. |
| Tile Adhesive (Mastic) | Small dry areas, wall tiles | ⭐⭐ (Limited) | Easy | Not good for floor tiles or wet places. Quicker to apply but less strong. |
Step 4: Mix Mortar and Apply to Subfloor
Mix the Mortar
Begin by mixing the thinset mortar as per the instructions. Use a clean bucket and a mixing paddle attached to a drill for a smooth mix without lumps. Allow the mortar to sit for a few minutes, then mix again before use.
Spread the Mortar
With a notched trowel, spread the mortar evenly on a small part of the subfloor. Hold the trowel at a 45-degree angle to make consistent ridges. These ridges help tiles stick well and ensure a level installation.
Work in Small Sections
Only cover as much area as you can tile in about 10–15 minutes. This keeps the mortar from drying out before you place the tiles.
Pro Tip:
For larger tiles, apply a thin layer of mortar to the back of the tile for better hold, especially for tiles larger than 12 inches.
Step 5: Lay the First Tiles
Getting started right will make the whole project better.
Start at the Center Point
Use chalk lines to begin at the room’s middle or a main point. This makes sure tiles are spread out evenly.
Place the First Tile
Put the first tile on the mortar. Press down hard and twist a bit to make it stick well.
Use Tile Spacers
Put spacers between tiles to keep the gaps even for grout. This gives a neat, professional look.
Check Level
After setting a few tiles, use a level to make sure the surface is flat. Adjust if needed before the mortar dries.
Pro Tip:
Work in small areas so the mortar stays wet until the tiles are in place!
Step 6: Cutting Tiles to Fit
Cutting correctly is important for a nice, professional look.
Measure and Mark
Use a tape measure to find the size you need. Mark the line clearly with a pencil or wax pencil.
Choose the Right Tool
For straight cuts, a manual tile cutter is good.
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 avoid dust. Wear safety glasses and gloves to stay safe.
Pro Tip:
Measure twice before cutting to save material and get a perfect fit!
Step 7: Install Remaining Tiles and Let Mortar Cure
Begin placing the first tiles, then continue setting tiles one row at a time. Start from your initial spot, and use 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 newly placed tiles to keep them from moving. Handle small sections so the mortar stays wet until tiles are set.
Once all tiles are in place, let the mortar cure for at least 24 hours (or as the manufacturer suggests) before grouting. Proper curing is crucial for a strong and lasting tile floor.
Step 8: Apply Grout
When the mortar is ready, you can start grouting between the tiles:
Mix the Grout
Follow the steps on the package to mix the grout until it is smooth like peanut butter.Spread Grout Using a Float
Use a rubber float at a 45° angle to spread the grout on the tiles. Press hard to fill all the joints.Remove Excess Grout
After filling, hold 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 often and avoid taking grout out of the joints.Final Buffing
When grout starts to haze (after 30–60 minutes), use a dry microfiber cloth to clean the surface and remove the haze.
Step 9: Clean and Seal the Floor
Clean Grout Haze
After grout dries (usually 24 to 48 hours), you might see a cloudy film on tiles. Use a damp sponge or special grout haze cleaner to gently wipe tiles. Be careful not to touch the grout lines.
Use Grout Sealer
If the grout maker suggests, apply a grout sealer to keep it safe from water, stains, and mold. Use a small brush or a sealer bottle with a roller for careful application. Let the sealer dry completely as per the instructions.
Put Back Baseboards and Transition Strips
Once everything is neat and dry, put back your baseboards and add transition strips between different floors or rooms. This makes your tile floor look complete and professional.

Pro Tips for a Successful Tile Flooring Installation
Want to achieve great results with your DIY tile project? Remember these tips:
- Save time by organizing tools and tiles before starting. Keep tiles and tools close by.
- Use a top-quality wet saw for neat cuts, especially with porcelain tiles.
- Mix small amounts of mortar and grout. This stops them from drying out too soon.
- Check for level often with a spirit level while laying tiles.
- Work in small sections. This keeps mortar from drying before tiles are set.
- Minimize breakage. Cut tiles slowly and wear safety glasses.
Common Mistakes to Avoid When Installing Tile Flooring
Even skilled DIYers can make these mistakes:
- Skipping subfloor leveling. An uneven subfloor can lead to cracked tiles and uneven lines.
- Forgetting spacers. Uneven grout lines result in an unprofessional finish.
- Walking on tiles before the mortar sets. This can move tiles and mess up alignment.
- Using too much or too little mortar. This leads to poor stickiness or uneven tiles.
- Not cleaning grout haze quickly. Leaving grout haze too long makes it hard to remove.
