WR Meadows CERA-ROD 1/2 Inch Backer Rod - 2500 LF Carton
WR Meadows CERA-ROD is a closed-cell, round, flexible, continuous-length backer rod extruded from cross-linked polyethylene. It is non-absorbent, non-gassing, non-staining, and non-shrinking, and it keeps its original diameter when exposed to high sealant temperatures. In joints or large cracks in Portland cement or asphalt concrete, it sets the correct sealant reservoir, holds joint depth, stops sealant run-out through the bottom of the joint, and acts as a bond breaker against bottom-side adhesion.
Key Features
- Works in concrete joints and cracks and in asphalt cracks
- Will not melt, shrink, evaporate, or stain with hot-applied sealants
- Keeps its original diameter and stays non-gassing at high sealant temperatures
- Prevents run-out through voids or the joint bottom, which reduces sealant loss
- Acts as a bond breaker so sealant does not adhere to the joint bottom
Applications
- Joints and large cracks in Portland cement concrete
- Joints and large cracks in asphalt concrete
- Crack and joint sealing with hot-applied sealants
- Joints that need a controlled sealant reservoir depth

Frequently Asked Questions
What sealants is CERA-ROD used with?
CERA-ROD is intended for hot-applied joint sealants. It will not melt, shrink, evaporate, or stain, and it stays non-gassing when exposed to high sealant temperatures. Its temperature limit is 410 F (210 C).
How do I choose the CERA-ROD diameter?
For joint widths up to 3/4 inch, choose a rod 1/8 inch larger than the joint width. For joints 3/4 inch and wider, add 1/4 inch to the joint width when selecting the rod. CERA-ROD must be held in compression to work.
How is CERA-ROD installed?
Remove all dirt and foreign matter from the crack or joint. Install the rod with a single-wheeled or three-wheeled roller, depending on the work, and avoid stretching or puncturing it.
How soon can sealant go on after CERA-ROD is installed?
Hot-applied joint sealants from WR Meadows can go on immediately after the rod is in place.
