Den Braven PU Foam Backing Cord PU Foam Joint Backing Rod

Den Braven PU Foam Backing Cord is a flexible PU foam backing rod designed to control sealant depth in suitable joints and expansion gaps. It helps provide the correct joint profile while reducing unnecessary sealant consumption and supporting effective adhesion to the intended joint surfaces. It is a practical accessory for contractors, sealant applicators, construction professionals and maintenance teams across South Africa.

Den Braven PU Foam Backing Cord is suitable for use behind compatible sealants in expansion joints, construction joints and other suitable gaps. The flexible foam material can be compressed to fit the joint and helps establish a consistent sealant depth. Proper sizing is important to ensure the backing cord fits securely without being excessively compressed or stretched.

Den Braven PU Foam Backing Cord provides a convenient solution for preparing joints before sealant application. By controlling the depth of the sealant bead, it can help improve material efficiency and support the intended movement and performance of a suitable joint sealing system. Always select the appropriate cord diameter for the joint dimensions and specified sealant system.

For best results, ensure the joint is clean, dry and free from loose material before installation. Insert the backing cord to the required depth without damaging the foam, then apply the compatible sealant according to the manufacturer's recommended procedure.

For South African construction, waterproofing, expansion joint and maintenance projects, Den Braven PU Foam Backing Cord offers a practical solution for joint preparation. It is a useful choice where controlled sealant depth, efficient material use and professional joint finishing are required.
