🛠️ Seal smarter, not harder — the pro’s secret to flawless joints!
The SIKA Backer Rod is a 3/4" diameter, 20-foot long closed-cell polyethylene foam rod designed to partially fill deep cracks and joints before sealant application. It controls sealant depth, prevents three-sided adhesion, and offers excellent resistance to water, oils, and solvents. Lightweight and flexible, it’s perfect for professional-grade glazing, expansion joints, and perimeter sealing, ensuring durable, moisture-resistant finishes.
