Product description: Backing Rod is a versatile and essential component for joint sealant applications, designed to provide a reliable backing for cold-applied sealants in expansion and construction joints. Made from compressible, closed-cell polyolefin foam, this gap filler rod ensures an even depth and shape for the sealant, promoting a strong and lasting bond. It prevents sealant from adhering to the bottom of joints, allowing it to function as a bond breaker.
Available in various sizes, Backing Rod conforms to AU/NZ standards for quality and performance. The sizes include 6mm x 250m, 10mm x 200m, 13mm x 100m, 15mm x 100m, 20mm x 60m, 25mm x 50m, 30mm x 50m, 40mm x 2m, and 50mm x 2m. Its compressible nature allows it to fit snugly into joints, preventing sealant sagging and ensuring optimal performance.
The closed-cell structure provides excellent dimensional stability, resistance to most chemicals, and rot-proof properties. It is non-toxic, odourless, and does not adhere to sealants, making it highly durable with excellent aging characteristics.
