DESCRIPTION
The SikaSeal 414 Backer Rod is a high-quality, non-absorbent, compressible backing material manufactured from grey closed-cell polyethylene foam. It is specifically designed to support the correct installation and performance of cold-applied joint sealants across a wide range of construction and sealing applications.
When installed within joints, SikaSeal 414 Backer Rod helps control sealant depth, ensuring the correct joint geometry and reducing unnecessary sealant usage. Its closed-cell structure prevents moisture absorption, making it suitable for both internal and external applications where long-term durability is required.
The backer rod also acts as an effective bond breaker, preventing three-sided adhesion and allowing the sealant to move freely within the joint. This improves joint performance, accommodates movement, and reduces the risk of sealant failure. In addition, it creates a firm backstop that supports accurate sealant tooling, resulting in a clean, professional finish.
Easy to install and highly compressible, SikaSeal 414 Backer Rod can be used in expansion joints, movement joints, façade joints, glazing applications, and general construction sealing where controlled sealant depth and reliable performance are essential.
