NO. 790

CERA-ROD

NON-GASSING, HEAT-RESISTANT BACKER ROD
Retains original diameter when used with hot-applied sealants. SEALTIGHT CERA-ROD Non-Gassing, Heat-Resistant Backer Rod provides correct form and control depth for proper joint configurations. CERA-ROD retains its original diameter and will not shrink, melt or emit gas when used with hot or cold-applied joint sealants.

Technical 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 25 % at 8 psi (55.2 KPa).

Uses
CERA-ROD is used in joints or large cracks in Portland Cement or asphaltic 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. The product works equally well with either hot or cold-applied sealants.

Advantages and Benefits

Application Tools

 
Three-Wheeled Roller

 

Application
JOINT OR CRACK PREPARATION: Remove all dirt and foreign matter.

METHOD OF APPLICATION: Install CERA-ROD with a double-wheeled roller or any smooth, blunt instrument that will insert the material without stretching or puncturing it. 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. All SEALTIGHT hot-applied or cold-applied joint sealant applications can follow immediately.

Packaging
