Soft Type Backer Rod is a soft, grey, pliable, non-gassing backup material inserted into an expansion or contraction joint to control sealant depth, create a backstop to allow proper tooling, ensure sealant adhesion to joint surfaces only and to yield a proper bond break between backup material and sealant.
Ideal in irregular joint applications particularly where self-leveling, flowable sealants are employed. Compatible with all known cold applied sealants including butyl, polysulfide, acrylic, polyurethane and silicone.
