About this item
- Package Content: Contains 1 backer rod with a diameter of 5mm / 0.2 inch and a total length of 3000cm / 98Ft.
- Durable Rubber Material: This backing rod is made of flexible silicone rubber and offers reliable adhesion and moisture resistance. It performs consistently across a wide range of temperatures. Suitable for both indoor and outdoor use, this foam strip provides a long-lasting seal that resists degradation and waterproofing.
- Closed-cell closed design: The closed-cell structure effectively prevents moisture absorption, creating an optimal backing for sealants. This design ensures a tight air and water barrier, enhancing caulking results. It retains its shape under pressure, offers reliable sound and thermal insulation, and supports energy efficiency while reducing noise transmission.
- Easy Installation: To install, measure the gap, cut to length with scissors, and press firmly into the joint or crack. Position it at the proper depth to achieve a professional finish. This method prevents three-sided adhesion and reduces sealant waste, saving time and material.
- Wide Applications: This versatile gap filler is perfect for multiple sealing tasks. Use it to fill concrete expansion joints, pavement cracks, and wall seams before caulking. It also functions effectively as weather stripping around doors, windows, and closets. Suitable for automotive and marine applications, it seals against airflow, dust, and noise.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
