How to Prepare Subfloor for Tile | The Home Depot!


This article discusses how to prepare a subfloor for tile installation. The subfloor is the base layer beneath the actual flooring, and it is important to ensure that it is properly prepared to ensure a successful tile installation.

To begin, it is crucial to inspect the subfloor for any damage, such as loose boards or cracks. These issues should be repaired or replaced before moving forward. Next, any debris, dust, or dirt should be thoroughly cleaned from the subfloor. This can be done using a vacuum cleaner or broom.

Once the subfloor is clean, it should be leveled. If there are any uneven areas, they should be filled using a leveling compound.


This compound should be spread out evenly across the subfloor using a trowel. It is important to follow the manufacturer's instructions when using the leveling compound.

After the leveling compound has dried, it is necessary to apply a layer of thin-set mortar to the subfloor. This creates a strong bond between the tile and the subfloor. The mortar should be applied using a notched trowel, ensuring that it is spread evenly.

Finally, the subfloor is ready for tile installation. It is important to select the right type of tile adhesive for the specific tile being installed.


The tiles should be laid out carefully, with spacers used to ensure even gaps between each tile. The adhesive should be allowed to dry completely before grouting.

In conclusion, preparing the subfloor is an essential step in ensuring a successful tile installation. By inspecting, cleaning, leveling, and applying the appropriate materials, the subfloor will be ready to support the tile and provide a long-lasting and durable flooring surface.
