Have you heard about a backer rod and what it does? If you are looking for a simple yet useful material that will serve as backing in joints or gaps and create a backstop, then it is what you are looking for. This humble foam comes in different sizes or diameters, allowing you to select the one for the optimal backing of the joint you need to seal. Apart from the shape, a crucial feature of the rod is that it is available in different types of foam cell structures. These include closed-cell structure, open-cell structure, and bi-cellular.
It is so important to know that it is the specific cell structure of a backer rod that largely influences how it works for a certain application. It can particularly affect the desired flexibility of the joint and the specific sealant to be used for the task. Most often, backer rods are made from polyethylene or polyurethane foam, making them suitable for common caulking materials and joint sealants.
The key benefits that a backer rod provides are so diverse. It increases the elasticity of the sealant, reduces caulking consumption by regulating the depth of the sealant, which prevents its excessive use. Another important benefit it offers is that it drives the bond material to come into contact with the sides of the joint that creates a superior bond. More importantly, it also creates a bond-breaker that enables the joint to be cleaned quickly and easily as well as for easier refilling later on.
So, if your application will particularly benefit from the use of this foam material, but you are not sure which one you need, simply ring us up. We can help you determine the right backer rod for your project, we do it by helping you know all the things that can impact its use for your specific application, whether it is for interior or exterior installation.
