A good place to purchase a backer rod is the concrete supplies section of your local hardware store. It comes in two sizes: a large one that is 29 fluid ounces and a small one that is only 10 fluid ounces. If you need a large one, I recommend getting two tubes and slicing them in half so that you can use the smaller one. A backer rod can make a big difference in the look of your basement.
A cylinder-shaped piece of foam called backer rod is a material that is used to fill the gaps between building materials. Backer rods are important because they ensure the proper hour-glass shape when the building sealant is applied. They also prevent the sealant from adhesion to itself or other materials in a three-sided manner. They should be installed at consistent depths along the joint length and have a thickness equal to the sealant application's final depth.
Depending on the width of the crack, choose a backer rod with a diameter slightly larger than the gap in the joint. For smaller joints, allow three millimeters, while larger joints need a diameter twenty-five percent larger. To fill cracks, you can also use soft tools like rollers or brushes to avoid puncturing them. Using soft tools helps prevent the rod from bending, puncturing the surface.
Backer rods should be flexible enough to stretch and return to their original shape. A closed cell product will not wick moisture, which is important for joints that tend to be wet. A closed cell rod will also improve the bond between the sealant and its backing material. Closed cell products have greater bonding surface area than open cell products. Closed cell PE backer rods include FillPro Standard and Armacell Hot Rod XL.
