CRL B0CBR2 Black 2" Open Cell Backer Rod - 102 ft

C.R. Laurence B0CBR2 Black 2" Open Cell Backer Rod - 102' is an essential tool for effective sealant application in vertical wall joints. This soft, round polyurethane foam backer rod features an open cell design that is compatible with all cold-applied sealants, ensuring optimal adhesion and performance. Its flexibility accommodates dynamic joint movement, making it ideal for areas with potential joint damage while preventing sealant failures caused by outgassing. Measuring 2 inches in diameter, the backer rod should be oversized by 50% for a secure fit, controlling the depth of the sealant bead and acting as a bond breaker. Designed for use in temperatures ranging from -65°F to 400°F, it is highly recommended for high-performance sealants such as silicones and urethanes. Ease of installation is another advantage, as the backer rod is packaged on convenient spools and can be inserted with a blunt tool or roller. However, it is important to note that this product is not suitable for horizontal traffic joints or hot-applied sealants. To ensure the best results, joints must be clean and dry prior to installation. For a reliable solution to your sealing needs, trust C.R. Laurence B0CBR2 Open Cell Backer Rod to enhance the longevity of your sealants.
