Transform your home with our detailed guide on How to Install porcelain floor tile? Installing porcelain floor tile is a project that can really pay off by improving your home’s appearance and value.
In this complete guide, we will teach you how to get the tidying done in the right way with clear step by step instructions, helpful tips, and handy insights to make the whole process a success.
To install porcelain floor tiles, start by preparing the surface to ensure it is clean, level, and dry. Next, measure and mark the center of the room to create a guide for tile placement. When learning how to lay porcelain floor tiles, apply thin-set mortar to a small area using a notched trowel, then set the tiles one at a time, pressing them firmly into place.
Use tile spacers to ensure even gaps between each tile. After the mortar dries, apply grout between the tiles and wipe away excess grout. Follow these steps for porcelain tile installation, and allow the floor to cure for 24-48 hours before walking
Tools and Materials You’ll Need
First you need to gather all the necessary tools and materials. You will have all the pieces you need should you need to install it.

Tools:
- Notched trowel (1/4 inch for most tiles)
- Tile spacers (1/8 or 1/16 inch, depending on your grout width)
- Tile cutter (manual or electric, based on tile thickness)
- Grout float
- Measuring tape
- Rubber mallet
- Level
- Bucket and sponge
Materials:
- Porcelain floor tiles
- Thin-set mortar (suitable for porcelain)
- Grout (sanded or un sanded, depending on grout width)
- Tile sealer (optional, depending on grout type)
Step 1: Prepare the Subfloor
For a long lasting floor tile installation, you need a stable, clean subfloor. And here’s how to make it ready for tiles.

1.1 Clean and Inspect the Sub Floor
- Dust, dirt, debris may be swept and mopped away.
- Look for spots that are not even cracks, dips, or bumps can cause loose or cracked tiles.
1.2 Level and Secure
- Use a level to check for high or low points.
- For minor uneven areas, apply a floor leveling compound.
- If your subfloor is plywood, secure it with screws every 8 inches.
Step 2: Plan Your Tile Layout
Planning the layout is critical to avoid small cuts or uneven edges. Take your time with this step to achieve a professional look.

2.1 Find the Room’s Center
- Measure and mark the room's center by snapping chalk lines from the midpoint of each wall.
- Where the lines intersect is your center point this is where you’ll begin laying tiles.
2.2 Dry Layout
- Lay tiles without adhesive along the chalk lines to see how they’ll look.
- Adjust the layout to avoid having narrow tile slivers on any side, as these can weaken the installation.
Step 3: Mix and Apply Thin-Set Mortar
By mixing and applying it right, your tiles stay in place with the thin set mortar.
3.1 Mix Mortar Properly
- Read and follow the manufacturer’s directions exactly.
- Don’t mix so much in advance that you are left with dried out cake.
3.2 Apply the Mortar
- Using the notched trowel spread the mortar in small section (3-4 square feet).
- Make ridges the width of your trowel by holding the trowel at a 45 degree angle for maximum adhesion.
Step 4: Set the Tiles
With the mortar spread, it’s time to start laying your tiles.

4.1 Press and Position Tiles
- Starting from the center point, press each tile into the mortar firmly.
- Tiles must be set with tile spacers so that the grout lines between tiles will remain consistent.
4.2 Check Alignment
- After every few tiles, check with a level to ensure they are even.
- Use a rubber mallet for slight adjustments if any tile sits higher than others.
Step 5: Cutting Tiles to Fit
Not all tiles will fit perfectly around edges or obstacles. Cut tiles to the required size, using tile cutter.

5.1 Mark and Measure
- Measure the space that needs a cut tile and mark it with a pencil.
- Always cut a tile slightly smaller than the actual space to allow for grout.
5.2 Use the Tile Cutter
- For simple cuts, use a manual tile cutter. For intricate cuts or harder porcelain, a wet saw is ideal.
Step 6: Allow Mortar to Cure
Let the tiles set according to the thin-set manufacturer’s instructions.

- Avoid treading on the tiles when curing (usually for 24 hours).
- However, curing time depends on the temperature and humidity of the room.
Step 7: Apply Grout
Once the tiles are securely set, grout fills the spaces between tiles and provides a polished finish.

7.1 Choose the Right Grout Type
- For joints wider than 1/8 inch, use sanded grout.
- For narrower joints, un sanded grout is ideal for a smooth finish.
7.2 Apply the Grout
- Spread grout over the tiles with a grout float held at a 45-degree angle.
- Use a diagonal motion to press the grout into the joints, covering all gaps.
Step 8: Clean Off Excess Grout
There are times when you may leave excess grout so that it leaves a haze on your tiles and for that reason it is so important to remove it gently.

8.1 Initial Cleaning
- 10 to 15 minutes, once you’re done let the grout set, then use a damp sponge to clean up the excess.
- Wash your sponge often to prevent grout haze leaving marks on tiles.
8.2 Final Buffing
- After grout has dried completely, clean any remaining haze from grout out of the tiles using a dry cloth or buffing pad.
Step 9: Sealing (Optional)
Sealing some grouts protects against stains and moisture.
- After the manufacturer’s instruction, apply sealer and focus on the grout lines.
- Use the floor fully allowed to cure.
Further Installation Tips for Success
- Mind Your Mix: Don’t use too much mortar or grout at one time, because it will dry before you get to it.
- Consistent Spacing: You can become consistent with the use of tile spacers to get professional grout lines.
- Allow for Expansion: Provide a small space all around the perimeter of the room for the environment to expand and contract naturally.
Common Mistakes to Avoid
It is important to avoid common tiling mistakes to get to the professional result.
- Not Leveling the Floor: Bypassing this step means it's possible that tiles will crack or even pop up, especially if continued use causes additional weight on the system.
- Skipping the Dry Layout: If you don’t have a dry layout, you may end up with uneven tiles and awkward cuts.
- Applying Mortar Over Too Large an Area: As drying mortar is quick, working in small sections will guarantee adhesion.
