In this detailed guide, we'll cover everything you need to know about using a backer rod.

How to Effectively Use a Backer Rod?

When using a foam rod, it is important to ensure that the rod is properly positioned in order to maximize its effectiveness.
The foam rod should be placed so that it is level with the surface of the joint and extends slightly beyond the ends of the joint. It is also important to compress the backer rod slightly in order to create a tight seal.
Once the foam rod is in place, you can begin applying your sealant. It is important to evenly distribute the sealant over the length of the joint, making sure to fill any voids or gaps. After the sealant has been applied, you can use a tool to smooth it out and create a uniform appearance.
