What is the 10 mm Abelrod used for?

It is a closed-cell polyethylene backer rod pressed into joints before sealing. It sets the correct sealant depth, breaks the bond to the joint base and improves long-term sealant performance.

What joint width suits the 10 mm rod?

The 10 mm rod compresses into joints around 8–12 mm wide. For wider joints, step up to the 13 mm or 20 mm Abelrod for the right compression and sealant depth.

Is Abelrod compatible with all sealants?

Yes. The closed-cell structure resists sealant absorption and is compatible with most polyurethane, silicone and MS polymer sealants used on construction joints.

How is Abelrod installed?

Roll the backer rod into the joint with a blunt tool to the required depth. Avoid puncturing the closed-cell skin, then apply your sealant over the top.

What is the shelf life?

Shelf life is unlimited when the rod is stored in a cool, dry place out of direct sunlight.
