6mm Backer Rod

6mm Backer Rod

Closed cell joint backing foam also known as backer rod or polycord, is a flexible polyethylene cord. It allows the volume of sealant or mastic used to be minimized and reduce overall cost as well as allowing the user to obtain the optimum sealant shape or design, which prevents joint failure. Foam backer rod is chemically and physically neutral, which is non-absorbent and will not rot. It can also be incorporated into side insulation and expansion joints preventing heat loss and provide acoustic properties.

Backer rod is a flexible foam material used in construction projects to fill gaps and voids between two building materials. It is commonly used as an alternative to other sealing methods, such as caulking or foam insulation, to provide an effective and long-lasting seal. The primary purpose of backer rod is to control the depth of the sealant and prevent it from bonding too deeply into the joint. This allows the sealant to maintain its flexibility and stability over time, avoiding cracking or breaking under pressure.

Backer rod is typically made from a closed-cell foam material, such as polyethylene or polyurethane, which is flexible and compressible. This allows it to conform to the shape of the joint and provide a consistent and uniform seal. It also helps to control the flow of the sealant, ensuring that it is distributed evenly and adheres to the surfaces of the joint.

When installing backer rod, it is important to carefully measure and cut the rod to the correct length for the joint. The rod should be inserted into the joint, pushing it down until it reaches the bottom of the joint. This will create a cushion for the sealant, providing a stable base for it to adhere to. It is important to avoid over-compressing the backer rod, as this can cause it to lose its shape and affect the performance of the sealant.

Once the backer rod has been installed, it should be left in place for a few hours to allow it to settle into the joint. This will ensure that it is properly positioned and provides a consistent base for the sealant. When applying the sealant, it is important to use the right tools and materials, such as a silicone gun or a sealing tool, to ensure that the sealant is distributed evenly and adheres properly to the surfaces of the joint.

In addition to backer rod, there are other tools and materials that can be used to achieve a perfect silicone joint, including silicone sealants, and tapes. These products can help to ensure that the joint is properly sealed and protected from moisture, air, and other elements that can cause damage over time.
