Oodles Of Noodles Closed Cell Foam Backer Rod For Caulking And Joint Depth Control Grey 4 Inch Diameter By 72 Inch Long 1 Pack

The Oodles of Noodles Closed-Cell Foam Backer Rod is a high-performance polyethylene foam solution designed to provide structural depth control for heavy-duty sealing and construction applications. Engineered specifically for large-scale concrete expansion joints, driveway cracks, and highway pavement joints, this flexible round foam rod acts as an ideal backing support. It limits the depth of elastomeric, silicone, polyurethane, acrylic, latex, or butyl sealants, ensuring you use just the right amount of caulk while promoting an optimal structural shape for max elasticity. Made from chemically inert, stain-resistant, and non-absorbent polyethylene, it repels moisture and withstands extreme ambient temperatures ranging from minus ninety degrees Fahrenheit to one hundred and ninety degrees Fahrenheit. Beyond commercial and residential masonry or glazing repairs, its substantial four-inch diameter serves as excellent structural cushioning, protective padding, or specialized craft foam. This durable foam rod offers over ninety percent compression recovery, meaning it maintains a snug fit inside varying joint widths without breaking down over time.
