Nulon PE Foam Backing Rod (50m Roll)
Available in sizes from 6mm to 25mm, backer rods are pushed into joint gaps to form a uniform and firm base for controlling the depth of gun-applied sealants.

It is perfect for:
- Joints between precast concrete panels
- Saw cut joints in concrete floors
- Peripheral joints around aluminium and timber windows
