Description
- Joint Backing Closed cell or reticulated polyethylene backer rod is recommended as joint backing to control sealant depth and to ensure intimate contact of sealant with joint walls when tooling. Where depth of joint will prevent the use of backer rod, an adhesive backed polyethylene tape (bond breaker tape) should be used to prevent three-sided adhesion. All backing should be dry at time of sealant application.
- Vulkem 116 is suitable for certain water immersion applications.
- Vulkem 116 is rated for +/-25% movement capability.
- Vulkem 116 is durable, flexible, and offers excellent performance in dynamic joints.
- Vulkem 116 has a 30-year history of delivering superior primerless adhesion to porous substrates, which makes it the choice for sealing expansion joints in commercial construction applications.
Vulkem 116 is a textured, single-component, moisture-curing, gun-grade polyurethane sealant. Vulkem 116 is an excellent general-purpose sealant designed for use on poured and precast concrete, masonry work, window and door perimeters, and similar types of construction joints.
