BACKER ROD FOR COLD-APPLIED SEALANTS

FLEXIBLE, CLOSED-CELL JOINT FILLER BACKING MATERIAL
SEALTIGHT KOOL-ROD is specifically designed as a compressible backing material to be used in conjunction with a wide variety of cold-applied joint sealants.

USES
SEALTIGHT KOOL-ROD is highly adaptable for both vertical and horizontal applications. It is commonly used in glazing operations, copings, between pre-cast panels, around door and window perimeters. It provides the perfect backing for all types of construction, expansion, isolation, control and pavement joints.

FEATURES / BENEFITS

• Controls depth of sealant / Ensures proper joint design ratio
• Forces sealant against joint sidewalls / Provides maximum sidewall adhesion
• Sealants will not adhere to KOOL-ROD / Eliminates 3-sided joint adhesion failure
• Closed cell foam technology / Does not allow air or moisture entrapment
• Easily compressible, lightweight / Installs quickly, stays in place
• New, easy to handle, smaller packaging / Added contractor convenience

INSTALLATION
Joint or opening must be clean, dry and free of obstructions. Select the proper rod diameter and cut to length or use directly from the spool. With a blunt instrument or roller, uniformly install rod at a level recommended by the sealant manufacturer, specifier or architect. Generally, the depth of the joint after KOOL-ROD is installed should be one-half the width. Very large and very small joints vary in terms of this depth-to-width ratio.

Do not tear, puncture, twist or overly compress the backer rod during installation. Caution should be used to avoid any situation where voids may form and trap air / moisture between backer rod and sealant. Care should also be taken to prevent the introduction of air bubbles into the sealant during mixing (if, any) and / or installation.
