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
 | Works equally well with concrete or asphaltic surfaces
| Use with either hot or cold-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 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.
