1. Joint or opening should be clean and dry and free of all contaminates, loose materials, dry, and free of water or frost.
2. To install, compress backer-rod into the joint
before sealants are applied. Install backer-rod using a blunt tool or a plain faced roller.
3. Force the rod to the depth recommended by sealant manufacturer, (typically about 1/2 of joint width measured at the crown of the backer rod). A template or roller gauge may be used to control the depth at which the rod is placed.

4. 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.

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

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