Description
Open cell backer rod is great in terms of application, it is very easy to compress and in can even help facilitate the cure of the sealant
from both sides instead of an outside to inside direction, or top down. Typically, sealants will cure through a reaction with
atmospheric moisture or evaporation. Using a permeable backer rod will allow the sealant to react with atmospheric moisture to cure
on the interior side. Open cell backer rod should not be used in flat or horizontal joints that can have water ponding on them as they
can wick moisture to the underside of the sealant.
• Suited for irregular and varying joint widths
• Backer rod limits the depth of sealants and helps the sealant form hourglass shape
• Serve as a bond breaker to prevent bottom-side adhesion
• Backer rods do not stain sealants, and are chemically inert, non-gassing, non-exuding, and virtually dust-free
• Compatible with virtually all known cold sealants
• Limits the depth of the sealant, thereby preventing excessive use of the sealant
Available in multiple diameters and sold per hundred lineal feet
