Product description
The Mada Gypsum Backing Rod is an essential component for professional gypsum board installation, serving as a depth controller and gap filler for expansion and control joints. Manufactured from high-density closed-cell polyethylene foam, this rod maintains its shape and provides a consistent backing that ensures the sealant achieves the correct depth-to-width ratio for optimal performance and durability.
Key Features
- Consistent Depth Control: Prevents the sealant from adhering to the bottom of the joint, ensuring single-sided adhesion which allows the joint to move freely without tearing the sealant.
- Closed-Cell Structure: Resistant to moisture, water, and chemical degradation, making it suitable for both interior and exterior applications.
- Easy Installation: Compressible enough to fit into various joint widths while maintaining structural integrity after installation.
- Compatibility: Designed to work seamlessly with Mada sealants and other standard construction adhesives.
Applications
Primarily used in drywall and gypsum board systems to fill gaps between panels before applying joint compound or sealant. It is also widely used in concrete and masonry construction for expansion joints, control joints, and perimeter joints where a flexible sealant is required.
