PE backfilling cord for deep joint preparation

PE backfilling cord fills the depth of joints and gaps before sealant application, ensuring the sealant achieves the correct thickness for optimal adhesion and flexibility. This closed-cell polyethylene cord is pressed into deep joints between frames, walls, floors and facade elements to create a firm backing surface at the right depth.

Without backfilling, sealant would fill the entire joint depth, creating an overly thick bead that cures slowly, wastes material and fails to stretch properly when the joint moves. The closed-cell structure prevents moisture absorption, maintaining the cord's shape and insulating properties over time.

This product is essential for professional window installation, facade sealing and expansion joint preparation in both new construction and renovation work. Correct joint preparation with backfilling cord is a requirement for sealant manufacturers' warranties, as it ensures the sealant works within its designed thickness range. The pack contains 5 pieces, providing sufficient material for multiple joint sealing tasks on a single project.
