What Is a Backer rod?

Backer rods are flexible polyethylene foam rods used to seal joints and gaps in construction projects. The foam is inserted into the joint before an adhesive or sealant is applied. It is designed to provide a watertight seal and maintain the integrity of the sealant. They are usually available in various sizes, ranging from 2mm to 50mm in diameter.

A backer rod is a great way to ensure the sealant forms a uniform layer across the entire joint. At the same time, it provides a backing that prevents the sealant from sagging or running. By providing a uniform backing, a backer rod will also help ensure that the sealant adheres correctly and that the joint remains sealed over time. It also helps keep joints from becoming clogged with dirt and debris.
