Are Backer Rods Really Useful?

A backer rod is a cylindrical foam rod that is inserted into an expansion joint or cracks before caulking. Its purpose is to fill the joint so that the caulk can be applied in a smaller bead, which will last longer and look better. But are these foam rods really helpful? In this blog post, we will explore the pros of using backing rods in order to help you make an informed decision about whether or not they are right for you.

What are backer rods?

Made of polyethylene foam, they are tools that help to seal gaps or cracks in a surface. The rod is placed into the crack and then covered with a sealant. This creates a barrier that helps to prevent water, air, and other materials from entering the crack. These rods come in different diameters and lengths, so they can be used for a variety of applications.

There are many benefits to using foam rods, including the following:

-They help to create a tight seal around the perimeter of a gap or crack, which can improve the overall appearance of the surface.

-They can save time and money by preventing the need for frequent repairs.

-They can extend the life of a surface by protecting it from weather damage and other wear and tear.

Overall, backer rods are an effective way to seal gaps and cracks in surfaces. They are easy to use and provide lasting protection against water damage and other elements.
