What Size Trowel For 12×24 Floor Tile? (Find Out Now!)
Are you planning to install tile floor in your home? When it comes to completing do-it-yourself flooring projects like this one, it is crucial to have the right tools on hand. Arguably, the most important tool you will need is a high-quality trowel.
The trowel you choose for your project will depend heavily on the tile size, how thick the mortar needs to be, and what type of surface you are working on.
In general, the best trowel to use for 12×24 floor tiles is a square-notched trowel with notches that are either ½-inch by ½-inch or ¼-inch by ½-inch. The size of the notches is important because it determines where the mortar collapses once the tile is installed and pressed down.
If you’re ready to jump into your DIY project, you are in the right place. Read on to learn more about the right trowel to choose and any other information you may need to make your flooring remodel a breeze.

What are Notched Trowels?
A notched trowel is a tool that is designed to spread mortar onto the surface of your floor, walls, and any other surface in your home. The design is quite simple, featuring just a handle and a flat metal plate with different tooth shapes around the edges.
The notches on the trowel help ensure you leave an even amount of mortar on the floor, so your tiles set properly.
Too much mortar will leave you with a terrible mess to clean, and it can cause the tiles not to set evenly. Too little mortar, on the other hand, won’t properly support the tiles. This will lead to weak spots and will eventually break the tiles all together.
Different Types of Notches
There are a few different types of notches that trowels can have. The notches themselves impact how much mortar will be between the tile and substrate. They help apply the mortar in even lines and create spaces between the lines of mortar, too. Here are the three shapes you should know about:
Square-notch trowels spread the most mortar out of the three types. They can have either square or rectangular notches that are great for tiles over 4 inches. As you may have gathered from the rest of this article, you’re better off completing any floor tile project with a square-notched trowel.
U-notch trowels can spread a fair amount of mortar. They feature small arch-shaped divots that line the edge of the trowel. It is best to use U-notch trowels for tiles that have at least one edge larger than 4 inches.
V-notch trowels have a continuous edge that zigzags like a saw. They are preferred for mosaic tiles, or tiles that are less than 4 inches. This is because this type of trowel spreads the least amount of mortar.
Proper Mortar Coverage
Using the proper amount of mortar is not just a suggestion; it’s a standard that the American National Standards Institute (ANSI) sets. For indoor spaces like bathroom floors, 80% is the minimum coverage.
The best way to make sure you have enough mortar down is to place a tile down and check it. If there are any gaps in coverage on the floor or the tile, you don’t have enough mortar down.
