No matter how well you take care of your home, there will always be the chance of something going wrong. One issue you may encounter is cracked tile flooring. While this problem is not always serious, it can be unsightly and can cause a trip hazard. 

Potential Causes of Cracked Tile Flooring

1. Poorly Installed Subfloor

If the subfloor is not level or is not secured correctly, the weight of the tile and grout can cause the floor to crack.

2. Using the Wrong Type of Mortar

If the mortar is too weak or not designed for use with ceramic tile, it can fail and cause the tile to crack.

3. Changes in Temperature

As the temperature changes, the tile and grout expand and contract. This can cause cracks in the tile or grout, especially if the tile is not properly secured.

4. Impact Damage

If something heavy is dropped on the floor, it can crack the tile. Even walking on the floor can cause the tile to break if the tile is not properly supported.

5. Use of Harsh Cleaning Chemicals

Some cleaning chemicals can be too harsh for tiles and cause them to crack.

6. Natural Disasters

Earthquakes, floods, and other natural disasters can damage tiles and cause them to crack.

Tips for Preventing Cracked Tile Flooring

Now that you know the potential causes of cracked tile flooring, it’s time to follow the tips on how to prevent them.

1. Inspect the Subfloor for Any Damage

If the subfloor is damaged, it can cause the tile flooring to crack. Be sure to repair any damage to the subfloor before installing new tile.

2. Use a Moisture Barrier

A moisture barrier helps to protect the tile flooring from moisture, which can cause the tile to crack. Make sure to install a moisture barrier before installing the tile.

3. Use a Tile Sealer

A tile sealer helps to protect the tile from damage and also makes it easier to clean. Always apply a sealer to the tile before grouting.

4. Use the Right Adhesive

The wrong adhesive can cause the tile to crack. Be sure to use an adhesive that is designed for use with tile.

5. Use the Right Grout

The wrong grout can also cause the tile to crack. Make sure that you are using grout that is suitable to use for tiles.

6. Avoid Using Cleaning Products That Contain Acid

Acidic cleaning products can damage the tile and cause it to crack. Invest in cleaning products that are designed for tile use.

7. Have the Tile Professionally Installed

This will help to ensure that the tile is installed correctly and won’t crack.
