Polypropylene joint sealing backer rod D=25mm 5m/pack

The AB polypropylene joint sealing backer rod D=25 mm is designed for filling gaps, joints and connections before applying sealant. The backer rod helps create the correct sealant depth and reduce unnecessary sealant consumption.

The joint filler cord is inserted into the gap as a backing material, helping the sealant perform better in moving joints and preventing adhesion to three joint surfaces at the same time. This supports better elasticity and long-term sealant durability.

The product diameter is 25 mm, and one pack contains 5 m of material. Before use, check the joint width and depth, as well as the compatibility of the selected sealant with the backer rod.
