SIZING BACKER-ROD: Select a backer-rod diameter that is approximately 25% larger than the width of the joint for very large sizes. Large size do not compress as easily.

APPLYING CLOSED CELL BACKER ROD:
1. Joint fillers have three major functions: Controls depth of the sealant in proper relation to joint width; Provides backing against which the sealant is applied, forcing the sealant to the sides of the joint; Prevents 3-sided bonding, ensuring proper function of sealant.
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. Don't 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
