When to Use a 1/2 Notch Trowel?

Choose the right trowel for a long-lasting tile job.

Choosing the right trowel size is essential to ensuring a tile job stands the test of time. Professionals with a full understanding of the principles involved require many types of trowels to cover various working conditions.

Know the Tile Type

Tile location and layout style are other factors to consider.

The material tile is made from is one determining factor for deciding on a trowel size. Generally, the accepted standard for ceramic tiles 8 inches or larger is a 1/4 inch square notch trowel.

Other Types of Notches

Trowels are manufactured with square, V, and U notches. Square notches and U notches are the most frequently used for applying the thin set mortar used for tile, where V notches are most often used for glue.

Special Concerns with Natural Stone Tiles

Natural stone, depending on the material and size, usually requires a 1/2 inch square notch trowel. The increased size and weight over standard ceramic tile demands a deeper bed of mortar. The porous nature of natural stone also demands a higher degree of coverage.
