Schluter Kerdi Square-Notch Trowel 1/8in x 1/8in – TRL-KER (1-Pack)

Overview

Meet the Schluter Kerdi Square-Notch Trowel, a compact tool purpose-built to help you lay Kerdi waterproofing membranes with confidence. Built for durable, repeatable results, it withstands daily use on professional projects and weekend renos alike.

Durable Design: The trowel's sturdy construction is designed for sustained performance, helping you work steadily through showers, bathrooms, or other tile installs where Kerdi membranes are involved. The reliable build reduces the need for frequent replacements, so you can focus on the job at hand.

Precise Application: The 1/8in x 1/8in square-notches deliver consistent thin-set mortar coverage, supporting even bead distribution as you apply Kerdi membranes. This helps promote proper adhesion and a clean substrate prep, especially on larger surfaces.

Ergonomic Handle: A thoughtfully shaped handle offers a comfortable grip and balance, reducing hand fatigue during longer tiling sessions. The result is smoother, less-strain tiling work, whether mounting a full bathroom wall or a multi-plane shower niche.

Precision Notches: The square-notch geometry is designed for accurate adhesive application across tiling projects, helping you achieve uniform coverage on varied surfaces and edge transitions. This is particularly helpful when working around curves or tight corners.

Long-Term Coverage: When used as directed in the Schluter Installation Handbook and Technical Data Sheet, this trowel is backed by a 2-year limited warranty against manufacturing defects. Follow guidelines and industry standards to maximize performance and durability.
