Schluter Kerdi Band Waterproofing Strip — 33 ft x 5 in x 4 mil

Overview

Schluter Kerdi Band Waterproofing Strip is a precision-made, ultrathin reinforcement strip designed to create a continuous moisture barrier at critical seams and transitions. The 0.1 mm thickness keeps tile surfaces flush, allowing you to tile with confidence while avoiding uneven edges that can telegraph through the finish. The strip’s flexible yet firm structure helps it maintain a tight seal at butt joints and floor-to-wall connections, even around corners. It is designed to work with Kerdi and Ditra membranes as well as Kerdi-Board panels, enabling cohesive multi-material projects that match a single aesthetic across surfaces. When installed according to the Schluter Installation Handbook and the current Technical Data Sheet, Kerdi Band supports a durable edge detail across interior wet zones such as bathrooms and kitchens, helping the finished space resist moisture intrusion and look consistently professional over time. The packaging provides a manageable length for typical projects, and the material cuts cleanly with standard tools, reducing install time and rework in busy job sites.
