KOOL-ROD
BACKER ROD FOR COLD-APPLIED SEALANTS

DESCRIPTION
KOOL-ROD is a closed cell, polyethylene, flexible, rope-like foam joint backing material.

This material is virtually non-absorbent and chemically inert to most solvents. KOOL-ROD will not stain or adhere to sealant materials. It is fully compatible with acrylic, butyl, polyurethane, polysulfide, silicone, and most other cold-applied sealant compounds.

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

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 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.
