CERA-ROD™

NON-GASSING, HEAT-RESISTANT BACKER ROD

DESCRIPTION
CERA-ROD is a 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 with concrete or asphalt surfaces.
  • 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.

PACKAGING
Cartons weigh 11 lbs. (4.99 kg) each, except the 1 ½” and 2” (38.1 and 50.8 mm) sizes that weigh 30 lbs. (13.61 kg) each.

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.
