Reliable joint sealing with PU backer rod
- Prevents unwanted three-sided adhesion: You prevent joint sealants from bonding to the bottom, allowing elastic sealants to expand and contract freely without cracking.
- Resistant to common chemicals: The open-cell polyurethane foam withstands direct contact with silicone, polyurethane, and acrylic sealants as well as mild acids.
- Quick and effortless installation: With its flexible 15 mm round profile, you easily press the backing material into construction joints at the exact depth.
With the Soudal pu backer rod, you ensure professional joint preparation and sealing for expansion and construction joints. This flexible round profile made of open-cell polyurethane foam prevents three-sided adhesion, allowing elastic sealants to expand and contract freely without cracking. Featuring a 15 mm diameter and a length of 1 m, it easily presses into roughly 10 mm wide joints, setting the correct depth while significantly reducing sealant usage. Highly resistant to silicone, polyurethane, polysulfide, and acrylic sealants, this versatile profile can also be used as a practical draught excluder.
