A backer rod is used for concrete precast building. Backer rods are inserted between the concrete panels to fill the gap, thus providing a ‘backer’ for the caulking that is applied. These backer rods can be used around doors, windows, wall joints, as well as foundations.
The closed cell backer rod is best in horizontal or flat joints. Backer Rod performs as a depth control for most known cold applied sealants and also helps sealant to assume the optimum hour-glass shape.
A backer rod is used for the following:
- Saves caulking material by controlling depth in the gaps of most joints
- Around doors, windows, wall joints and foundations
- Concrete precast building
- Provides additional insulation
- Blocks drafts
- Creates the required Hour Glass shape and depth for all joint sealants
Packaging
Backer Rod is available in a wide variety of diameters.
