Buying Guide for 1 1/2 Inch Backer Rod
Understanding Backer Rod
When I first encountered backer rod, I was curious about its purpose. Backer rod is a foam material used to fill gaps and joints before applying sealants. It plays a crucial role in ensuring a clean, professional finish. The 1 1/2 inch size is particularly versatile, fitting a variety of applications, which is why I decided to explore it further.
Why Choose 1 1/2 Inch Size
I found that the 1 1/2 inch backer rod is ideal for larger joints and gaps. Whether I’m sealing around windows, doors, or even in concrete joints, this size provides the right amount of support. It offers sufficient depth to accommodate different sealant applications, which is an advantage I appreciate.
Material Matters
During my research, I discovered that backer rods come in various materials, primarily closed-cell foam and open-cell foam.
