Sealant Dimensions
W = Sealant width, D = Sealant depth,
Expansion Joints- The minimum width and depth of any sealant application
should be 1/4" x 1/4" (6 mm x 6 mm). The depth (D) of sealant may be equal
to width (W) of joints that are less than 1/2" wide.
For joints ranging from 1/2" to 1" (13 mm to 25 mm) 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" (13 mm). For joints that are wider
than 1" (25 mm) contact Tremco Technical Services or your local Tremco
Sales Representative.
Cure Time
At 75 °F (23.9 °C), 50% RH a skin forms within 5 hr. Curing continues at a
rate of approximately 1/16" (1.6 mm) per day. The cure time will increase as
the temperature and/or humidity decrease. A good rule of thumb is one
additional day of cure for every 10 °F decrease in temperature. Cure time can
be decreased by adding water when using pails of Vulkem 45SSL. Please
refer to the Technical Bulletin No. S-17-01 on Vulkem 45SSL/445SSL
Activator that can be found on our website at: www.tremcosealants.com
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.
