APPLICATIONS:

SIZING SOFT BACKER-ROD:

Select a backer-rod diameter that is approximately 25% larger than the width of the joint.

APPLYING BACKER ROD:

1. Joint fillers have three major functions:

2. To install, compress backer-rod into the joint before sealants are applied. Joint or opening should be clean and dry and free of obstructions. Install backer-rod using a blunt probe or a plain faced roller to force the rod to the desired depth.

3. Compress to a depth of about 1/2 of the width measured at the crown of the backer rod.

4. A template or roller gauge may be used to control the depth at which the rod is placed.

5. Do not stretch, puncture or tear backer-rod during installation but gently force into the joint so that the backer-rod fits tight against the sides of the joint.

PRIMING:

1. Follow suggestions for joint-sealant application as directed by sealant manufacturer.

2. Where priming of the joint is necessary, primer should be applied only to the joint surfaces and allowed to dry before Backer-Rod is placed. DO NOT prime Backer-Rod.
