UCANVIN Waterproofing Membrane Band Roll — 30 Mils Thick, 5-Inch x 98.5-Ft Underlayment for Tiles & Showers

Overview

UCANVIN's Waterproofing Membrane Band Roll is a reliable tile underlayment designed to support projects from start to finish. The roll measures 30 mils in thickness and 5 inches in width, extending up to 98.5 feet to cover larger areas with fewer seams. Made from sturdy polyethylene fabric, this membrane creates a durable moisture barrier behind tiles in bathrooms, showers, and other wet zones. When installed following standard practices—such as aligning seams, using compatible adhesives, and ensuring proper overlap—the membrane can contribute to a smooth tile surface and a tidy, professional look. This is not a guarantee, but it may improve substrate performance in damp environments.

Material & Performance

The 30-mil thickness and flexible polyethylene fabric strike a balance between strength and adaptability, helping the membrane conform to curves and corners. The broad 5-inch width is designed to minimize seams on typical floor and wall layouts, while the long 98.5-foot length supports larger installations with fewer roll changes. Proper seam overlaps and adherence to installation guidelines remain essential for best results. This membrane is intended to work as part of a comprehensive tile installation plan in damp areas.

Installation Tips

Prepare a clean, dry substrate. Align seams with a tight overlap, and press firmly to ensure good contact with the substrate. Trim along edges to fit around fixtures, then proceed with tile, following your chosen mortar and grout system’s instructions. Allow proper curing times and seal joints as recommended by tile and adhesive suppliers.

Quality & Compliance

UCANVIN provides clear labeling and consistent thickness across the roll. While performance depends on correct application, this membrane is designed to integrate with common tiling systems and standard waterproofing practices. Always follow local building codes and manufacturer guidelines for the best results.
