What Size Notched Trowel Should You Use?

Choosing the right trowel notch size is crucial. The size of the notches determines the thickness of the adhesive layer. So, if you’re wondering what size notched trowel to use for a specific project, consider the tile size and the substrate. For example, a 12mm notched trowel is excellent for larger tiles that require a thicker adhesive layer to ensure proper adhesion and level placement. Here’s a rough guide to refer to:

  • 6mm Notched Trowel: Ideal for small tiles (less than 100mm).
  • 8mm Notched Trowel: Suitable for medium tiles (100mm-200mm).
  • 10mm Notched Trowel/ 12mm Notched Trowel: Perfect for medium to large tiles (greater than 200mm).
  • 15mm Notched Trowel/20mm Notched Trowel: Great for very large tiles.
  • 6/8mm & 10/12mm trowel for large format tiles (6mm for back-buttering the tile)

How to Use a Notched Trowel

Using a notched trowel effectively involves a few key steps:

  1. Preparation: Ensure your surface is clean, dry, and level. Any dust or debris can prevent the tile adhesive from bonding properly.
  2. Applying the Tile Adhesive: Scoop the adhesive with the smooth side of the trowel and spread it over a small area of the surface. This helps to initially spread the adhesive evenly. Our key suggestion is that you would want to be back-buttering the tiles.
  3. Creating the Grooves: Hold the trowel at a 45-degree angle and run the notched edge through the adhesive. This motion creates even grooves, ensuring uniform thickness.
  4. Setting the Tiles: Place your tiles onto the tile adhesive, pressing firmly and with a slight twisting motion to ensure they are set correctly and the adhesive spreads evenly underneath.

Tips for Best Results When Using A Notched Trowel
  • Work in Small Sections: Only spread tile adhesive over a small area at a time. This prevents the adhesive from drying out before you set the tiles.
  • Check for Coverage: Periodically lift a tile to ensure that the adhesive covers at least 80-90% of its back.
  • Clean as You Go: Clean any excess adhesive from the tile surface and your tools as you work to avoid a messy finish. Shop cleaners.
