These backer rod will only act as a support for the joint and you’ll need a sealant over it in order to keep it intact. However, what makes this material especially great compared to others is the fact that the sealants won’t stick to the rods itself, but only to the building materials or the joint which will provide a better flexibility for them. Bubbling will also not occur even if it’s accidentally punctured and it can be used as substitute for other types of backer rods like the closed-cell type. If you’re intrigued by it now, you’ll be more astounded as it can be used for different indoor construction needs: Expansion and Contraction joints; Chinking of log homes; maintenance of pavement constructions even for highways and bridges; Construction of Partitions for Wall curtains; and even glazing of windows.
Installation
A Soft backer rod is your best friend whether you’re working on filling gaps for tiles, bricks and many more. However, you just don’t do it recklessly. Since it’s part of your construction project, you must do it intricately and carefully.
- Find the Right Size of Rod. A Soft backer rod is available in various diameters. You could have a 63mm diameter rod which is the largest or a 10mm diameter which is the smallest. You should gauge properly what the size of the gap you’re going to fill. However, you must at least take note that the diameter should be a bit larger compared to the gap. This is to ensure that it will last longer even in the most extreme seasons like summer.
- Cut The Rod. In most cases, the length of rod you bought may exceed the actual gap. Just cut it accordingly and you’re good to go.
- Clean the Joint. It is empirical that you clean the joints beforehand. Be aware that it must not possess any kind of outside elements – dirt, contaminants, etc. You could use water-soaked cloth with detergent.
- Wait for the Joint to completely dry after cleaning it.
- Put the Rod. Now, it’s time to put the rod onto the joint. Just let it slide and stop when it reaches about a half inch below from the surface of the joint.
- Apply Sealant. Once the rod is in the indicated position, stick it there by pouring the sealant on the joint. Afterwards, intricately smooth the surface using a groover.
- Let it Dry
After this last step, you’ve completely managed to apply the rod and sealant properly on the joint. It’s that simple. So if you’re on the midst of construction or you’re planning for one, once you’re on the process where you have to use a soft backer rod, make sure to carefully follow these steps in order to reach your desired outcome.
