CERA-ROD™
NON-GASSING, HEAT-RESISTANT BACKER ROD
DESCRIPTION
CERA-ROD is a closed-cell, round, flexible, continuous-length, non-absorbent, non-gassing, non-staining and non-shrinking material extruded from a cross-linked polyethylene. Compression/deflection is approximately eight psi (55.2 KPa) at 25% deflection.
USES
CERA-ROD is used in joints or large cracks in Portland cement or asphalt concrete. It provides the correct sealant reservoir configuration, controls joint depth, and prevents sealant run-out through the bottom of the joint. CERA-ROD also acts as a bond-breaker to prevent bottom side sealant adhesion.
FEATURES/BENEFITS
- Works equally well in concrete joints/cracks or
asphalt cracks.
- Use with hot-applied joint sealants ... will
not melt, shrink, evaporate, or stain.
- Retains its original diameter and is non-gassing when exposed to high sealant temperatures.
- Prevents run-out through voids or bottom
of the joint ... saves sealant material.
- Acts as a bond breaker to stop sealant adhesion to the bottom side of the joint.
- Fast and easy to apply.

APPLICATION
Crack and Joint Preparation … Remove all dirt and foreign matter.
Application Method … Install CERA-ROD with a single-wheeled or three-wheeled roller, depending on application. Avoid stretching or puncturing the material. CERA-ROD needs to be held in compression to work effectively. The diameter of the rod should be 1/8" larger than the width of the joint for joint widths up to 3/4". For joints 3/4" and larger, add 1/4" to diameter rod selection. Applications for all hot-applied joint sealants from W. R. MEADOWS can follow immediately.
PRECAUTIONS
Read and follow application information
and Material Safety Data Sheet information.
