Description
Professional open cell foam backing rod for very wide joints, designed to regulate sealant depth and achieve the correct profile. The breathable structure aids curing while preventing three-sided adhesion, improving movement capability and durability. Suitable for polyurethane, hybrid, and silicone sealants across façades, precast elements, and interior joints. Compressible and easy to install, the 40mm x 30m roll is ideal for large-scale projects requiring consistent performance and reduced sealant consumption with clean, reliable tooling outcomes.
