How to Lay Ceramic Tile on Concrete: Step-by-Step Guide

1. Gather Your Supplies

Before starting, ensure you have the following tools and materials:

Ceramic tiles
Thin-set mortar (tile adhesive)
Notched trowel
Tile spacers
Grout
Grout float
Tile cutter or wet saw
Measuring tape
Level
Chalk line
Sponge and bucket
Rubber mallet
Safety gear (gloves, goggles, and knee pads)

2. Prepare the Concrete Surface

Proper preparation is key to ensuring the tiles adhere properly and last for years.

Clean the Concrete

Sweep and vacuum the concrete floor to remove dirt, dust, and debris.
Wash the floor with a mild detergent and water to remove grease or stains.
Allow the concrete to dry completely.

Inspect for Cracks and Uneven Areas

Check the concrete for cracks, holes, or uneven areas.
Use a concrete patching compound to fill in any imperfections.
Allow the patching compound to dry according to the manufacturer’s instructions.

Check for Moisture

Test the concrete for moisture by taping a plastic sheet to the floor and leaving it for 24 hours.
If condensation forms under the plastic, the concrete may need additional sealing or drying time.

3. Plan the Layout

Measure the room and mark the center using a chalk line. This will serve as your starting point.
Dry-fit the tiles to ensure they align properly and make any necessary adjustments.

4. Apply the Thin-Set Mortar

Mix the thin-set mortar according to the manufacturer’s instructions.
Using a notched trowel, spread the adhesive evenly over a small section of the concrete.
Work in manageable sections to prevent the adhesive from drying out before you lay the tiles.

5. Lay the Tiles

Start at the center of the room and place the first tile firmly into the adhesive.
Use tile spacers to maintain even gaps between tiles for grout lines.
Continue laying tiles, working outward from the center. Use a level to ensure the tiles are even.
Cut tiles as needed to fit around edges, corners, or obstacles using a tile cutter or wet saw.

6. Allow the Adhesive to Set

Let the adhesive dry for at least 24 hours or as recommended by the manufacturer.
Avoid walking on the tiles during this time to prevent shifting.

7. Apply Grout

Mix the grout according to the manufacturer’s instructions.
Use a grout float to spread the grout evenly over the tiles, pressing it into the gaps.
Wipe away excess grout with a damp sponge, being careful not to remove grout from the gaps.
Allow the grout to dry for the recommended time.

8. Seal the Grout

Once the grout is fully dry, apply a grout sealer to protect it from stains and moisture.
Allow the sealer to dry according to the manufacturer’s instructions.
