Description

PR102 Usage Guidelines
– Select a diameter greater than the joint width to ensure the backer rod is compressed when installed (typically 25% compression is acceptable).
– Push into the joint to a depth appropriate to the required depth of sealant. Ensure the depth is consistent along the joint length.
– Take care not to puncture the material as gas may be emitted from the cell structure which can react with the applied sealant. If this does happen, wait minimum of 30 minutes before applying sealant.
