Description
Overview

Applications
Use when spreading the mortar beneath standard DITRA.
Plan Your Installation
- Identify the membrane before choosing the tool: the 11/64-inch square notch is the standard-DITRA trowel size.
- Use it for the mortar layer bonding that membrane to the substrate, with the mortar preparation and embedding method in the DITRA instructions.
- Choose the tile-setting trowel separately according to the tile installation requirements.
- The manufacturer specifies a 1/4-inch square-notch trowel for DITRA-HEAT and DITRA-XL, distinct from this 11/64-inch DITRA tool.
Common Planning Questions
Is this also the KERDI trowel?
No. The dedicated KERDI trowel uses a smaller 1/8-inch square notch.
Should I select it just because the membrane name contains DITRA?
No. DITRA-HEAT and DITRA-XL have their own specified trowel size; confirm the exact membrane.
