DESCRIPTION
WATERPROOF JOINT SEALANT
 
VULKEM 116 is a one-component, moisture-curing, gun-applicable polyurethane sealant. VULKEM 116 is durable, flexible and provides excellent action on moving joints. Vulkem 116 does not require a primer for most construction materials.
 
MAIN APPLICATIONS

VULKEM 116 is an excellent general purpose sealant designed for use in precast, masonry, window frames and other similar construction joints. VULKEM 116 is suitable for continuous immersion in water and is designed for interior and exterior use.

APP
 
Joint Design
It can be used in any vertical or horizontal joint, designed according to standard architectural or engineering practices. The thickness of the joint must be 4 times the anticipated displacement. The displacement must not exceed 25% of the minimum thickness of the joint.
 
Joint Dimensions

For joints between ¼ – ½” (6.4 – 12.7mm) wide, the thickness/depth ratio must be the same. Joints ½” (12.7mm) or larger must have a sealant depth of at least ½” (12.7mm). The minimum size of the joint must be ¼” by ¼” (6.4mm by 6.4mm).
 
Surface Preparation

For good adhesion, the joint must be clean and dry. If release agents, masonry waterproofing agents, dust, loose mortar, or architectural paints are present, the joint surface may require brushing, sanding, grinding, cleaning with a solvent, and/or the application of a primer.
 
Cleaning and finishing

Finishing is recommended immediately after placement to ensure firm and intimate joint contact. Dry finishing is preferably recommended. Excess sealant on or adjacent to the joint can be carefully removed with Xylene or Toluene before the product has cured.
 
Joint filler

Bond Breaker Tape: Polyethylene Backer Rods are recommended for backing to control joint thickness. Where joint thickness precludes the use of joint filler, an adhesive polyethylene tape should be used to prevent trilateral bonding. Joint filler must be dry at time of sealant application.
 
App

VULKEM 116 is easy to apply with conventional caulking equipment. Fill the joint completely and finish. At 75ºF (24ºC), and 50% RH, a durable layer forms within 24 hours. Curing continues at a rate of 1/16” (1.6mm) thickness per day. Cure speed is reduced at lower temperatures and lower humidity.
 
Maintenance

Damaged sealant can be repaired. Consult your Tremco products distributor or SPC, SA Technical Assistance Department for repair procedures.
