Schluter Kerdi Square-Notch Trowel – Durable Metal 1/8″ x 1/8″ Notch

Description

Product Overview

The Schluter Kerdi Square-Notch Trowel is engineered for tiling professionals who demand accuracy and durability in every application. Crafted from high‑grade steel, the tool offers a robust construction that resists bending, warping, and corrosion, even after repeated exposure to wet mortar and tile adhesives. Its 1/8″ x 1/8″ square notch is precisely machined to deliver a consistent thin‑set layer, which is essential for achieving a flawless bond between Kerdi waterproofing membranes and tile surfaces. The trowel measures 11 x 5 x 4.5 inches and weighs just 12.8 ounces, providing a balanced feel that enhances control without sacrificing strength. An ergonomic, non‑slip handle is integrated into the design, reducing hand fatigue during long‑duration projects and allowing users to maintain a steady rhythm while spreading mortar. The product is backed by a two‑year limited warranty, reflecting Schluter’s confidence in its manufacturing quality and long‑term performance.

Usage

This trowel excels in a variety of tiling scenarios, from residential bathroom remodels to commercial floor installations. Its square‑notch geometry is specifically suited for the application of Schluter’s Kerdi‑C, Kerdi‑S, and Kerdi‑L waterproofing membranes, ensuring that the thin‑set mortar is applied at the optimal thickness for maximum adhesion and water resistance. The tool is equally effective when working with traditional cement boards, stone slabs, porcelain tiles, and ceramic mosaics. Because the notch size is calibrated for 1/8″ mortar coverage, installers can achieve a uniform layer without the need for multiple passes, which speeds up the workflow and reduces material waste. The ergonomic handle makes the trowel comfortable for both right‑handed and left‑handed users, and its lightweight profile allows for easy maneuverability in tight spaces, such as shower niches or under‑cabinet areas.

FAQ

What size mortar does the 1/8″ square notch apply?

Can I use this trowel with other brands of waterproofing membranes?

Yes, the trowel works well with any membrane that requires a thin‑set application at the 1/8″ thickness, including many generic cement‑based waterproofing products.

Is the ergonomic handle suitable for left‑handed users?

The handle is symmetrically designed, allowing both left‑ and right‑handed users to maintain a comfortable grip and control the mortar flow effectively.

How do I clean the trowel after use?

Rinse the blade with warm water immediately after each use to prevent mortar buildup. For stubborn residue, a mild detergent and a soft brush can be used without damaging the steel surface.

What does the two‑year warranty cover?

The warranty covers manufacturing defects in materials or workmanship when the trowel is used according to Schluter’s installation guidelines. It does not cover damage caused by improper use or accidental impact.
