Soft Backer Rod is particularly well suited for specialty applications where standard backer rods are not appropriate. Soft Backer Rod is ideal in irregular joint applications where self-leveling, flowable sealants are employed. Soft Backer Rod is also recommended for use with sealants where bubbling concerns arecritical. It is compatible with all known cold applied sealants including butyl, polysulfide, acrylic, polyurethane, and silicone. Soft Backer Rod may be used in place of most standard backer rod applications or as a temporary joint seal.
Joint or opening must be clean, dry, and free of obstructions. Using the “Size-to-Joint Width” table,select proper rod diameter and cut to length or use
directly from spool. With a blunt instrument or roller, uniformly install rod at the level recommended by the sealant manufacturer, specifier, or architect
involved. Generally, the depth of the joint after the backer rod is installed is one half the width. Very large or very small joints vary in terms of this depth
to width ratio. Avoid puncturing, stretching, or over compression.
