Easily Conforms to Joint Irregularities
Non-Gassing if Damaged
No Moisture Absorption
Sof® Rod is a state-of-the-art sealant
backing material combining the best properties of both open and closed cell
backer rods in a single, trouble-free product. Sof® Rod is a continuous length
of extruded polyolefin foam made with a non-absorbent outer skin and a highly
resilient interior network of open and closed cells. Sof® Rod will not out-gas
if ruptured. It can be used in temperatures from -45º to 160º F (-43º to 71º C).
Benefits: Backer rod limits the depth of
the sealant and prevents excessive sealant use. It also helps sealant assume
optimum shape factor to prolong sealant service life and acts as a barrier to
the flow of sealant through the joint.
Compatibility - Bi-cellular polyolefin
foam is basically an inert material; and therefore, it is compatible, both
physically and chemically, with virtually all known
cold applied sealants,
including self-leveling types.
Diameter of Rod: 5/8 in (16 mm)
Feet per Pack: 1550 ft (472 m)
Proper installation includes the following. Verify that the joint is clean,
moisture-free, and clear of obstructions. Use Sof® Rod in a diameter
approximately 25% larger than the joint. Always install using a blunt tool or
roller. The Backer Rod Insert Tool Set is designed specifically
for the smooth installation of all types of backer rods.

Do not tear, puncture, crease, over compress or stretch during insertion. Always
use the correct size backer rod for the particular application. Do not use with
hot applied sealants or hot melt adhesives where their surface temperature is
over 160 degrees F (71 degrees C).
