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.
