Product Description
Vulkem® 116 is a textured, single-component, moisture-curing, gun-grade
polyurethane sealant.
Basic Uses
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. Vulkem 116 is approved for exterior
use only.
Features and Benefits
• 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 suitable for certain water immersion applications.
• Vulkem 116 is rated for +/-25% movement capability.
• The cure of the sealant can be accelerated with the addition of the Vulkem
Catalyst 45/116.
• Vulkem 116 is durable, flexible, and offers excellent performance in
dynamic joints.

Limitations
• Do not apply Vulkem 116 over damp, green or contaminated surfaces.
• Vulkem 116 is approved for exterior use only. Do not use this product
inside an occupied building even if there are no occupants present during
use.
• Always utilize the sealant’s SDS found on our website at
www.tremcosealants.com for information on proper ventilation, Personal
Protective Equipment (PPE) and other health concerns.
• Do not use in chlorinated, potable, heavy or waste water.
• Although this product is paintable, this does not imply adhesion to and
compatibility with all paints. Please refer to Tremco Technical Bulletin No.
S-09-05 for more information.
Substrate Preparation
Surfaces must be sound and clean. All release agents, existing
waterproofing, dust, loose mortar, paints, other finishes or field applied
coating must be removed. This can be accomplished with a thorough wire
brushing, grinding, sandblasting, or solvent washing, depending on the
contamination.
Tremco recommends that surface temperatures be 40 ˚F (5 ˚C) or above at
the time the sealant is applied. If sealant must be applied in temperatures
below 40 ˚F, please refer to the Tremco Technical Bulletin for Applying
Sealants in Cold Conditions (No. S-08-44 rev 1) that can be found on our
website at www.tremcosealants.com
Priming
Vulkem 116 typically adheres to common construction substrates without
primers; however, Tremco always recommends that mock-up or field
adhesion test be performed on the actual materials being used on the job to
verify the need for a primer, proper cleaning and prep requirements. The field
adhesion test can be found in appendix X1 of ASTM C 1193, Standard Guide
for Use of Joint Sealants.
Where deemed necessary, use Vulkem Primer® #191 Low VOC QD for
porous substrates and TREMprime® Non-Porous Primer for metals and
plastics.
Application
Vulkem 116 is easy to apply with conventional caulking equipment. Ensure
that the backer rod is friction-fitted properly and any primers have been
applied.
Fill the joint completely with a proper width-to-depth ratio, and then tool to
ensure intimate contact of sealant with joint walls.
Dry tooling is always preferred, although xylene can be used in limited
amounts to slick the spatula if needed.
For a cleaner finish, mask the sides of the joint with tape prior to filling.
Joint Design
Vulkem 116 may be used in any vertical or horizontal joint designed in
accordance with accepted architectural/engineering practices. Joint width
should be 4 times anticipated movement, but not less than 1/4" (6 mm).
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.
