The foam backer rod is a material designed to shape joint cross-sections before filling them with flexible sealants. It is suitable for use in both interior and exterior joints, including vertical and horizontal applications.

Using a backer rod minimizes the consumption of sealants and ensures the joint maintains the proper shape, enhancing its durability and functionality over the long term.

Features of the Backer Rod:

• Closed-cell structure (polyethylene)
• Waterproof
• High chemical, UV, and aging resistance (compression and expansion movements)
• Suitable for horizontal, vertical, static, and expansion joints
• Flexible and elastic – does not restrict the movement of sealant in the joint
• Oval shape improves the joint’s durability and increases lateral sealant contact area
• Reduces sealant consumption by providing a shallower joint fill
• Easy and quick application

Applications:

• Profiling construction joints to prepare them for the application of sealants
• Filling expansion joints in building structures that require long-term durability
