Sealant dimensions
W = Sealant width, D = Sealant depth, C = Contact area.
EXPANSION JOINTS - The minimum width and depth of any
sealant application should be 1/4” by 1/4” (6mm by 6mm).
The depth (D) of sealant may be equal to the width (W) of
joints that are less than 1/2” wide. For joints ranging from
1/2” to 1” (13mm to 25mm) wide, the sealant depth should be
approximately one-half of the joint width.
The maximum depth (D) of any sealant application should be
1/2” (13mm). For joints that are wider than 1” (25 mm) contact
Tremco’s Technical Service Department, or your local Tremco
field representative.
WINDOWPERIMETERS–Forlletbeads,oranglebeadsaround
windows and doors, the sealant should exhibit a minimum
surface contact area (C) of 1/4” onto each substrate.
Surface preparations
Surfaces must be sound, clean, and dry. All release agents,
existing waterproofing, dust, loose mortar, laitance, paints, or
other finishes 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
Guide for Applying Sealants in Cold Weather that can be found
on our website at www.tremcosealants.com.
Priming
Where deemed necessary, use Vulkem Primer #171 for porous
substratesandTREMprimeNon-PorousPrimerformetalsand
plastics. 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. The field adhesion test can be found in appendixes
X1ofASTMC1193,StandardGuideforUseofJointSealants.
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 tool to insure 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.
Cure time
Vulkem 116 generally cures at a rate of 1/16” per day at
75°F (24°C) and 50% relative humidity. It will skin in 5 hours
and be tack free in 30 hours. The cure time will increase as
temperatures and/or humidity decrease. A good rule of thumb is
one additional day for every 10°F decrease in temperature.
Clean up
Excess sealant and smears adjacent to the joint interface can
be carefully removed with xylene or mineral spirits before the
sealant cures. Any utensils used for tooling can also be cleaned
with xylene or mineral spirits.
