SIZING SOFT BACKER-ROD:
Select a backer-rod diameter that is approximately 25% larger than the width of the joint.

Joint Width Diameter
3/16" - 1/4" 3/8"
3/8" - 1/2" 5/8"
1/2" - 3/4" 7/8"
3/4" - 7/8" 1-1/8"
7/8" - 1-1/4" 1-1/2"
1-1/4" - 1-1/2" 2"
2" - 2-1/2" 3"
2-1/2" - 3" 4"

APPLYING 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.
