Description
Professional open cell foam backing rod for joint preparation under sealants. It regulates sealant depth, prevents three-sided adhesion, and helps achieve proper width-to-depth ratios. The breathable, compressible foam supports curing and neat tooling. Suitable with polyurethane, hybrid, and silicone sealants in façade, glazing, and internal movement joints. The 15mm x 150m roll covers medium-sized joints efficiently, reducing material use and enhancing seal durability and performance across commercial and residential construction projects, both indoors and outdoors.
