APPLICATION
Joint Design:
The width of the joint should be a minimum of 4 times the anticipated movement. In joints up to 1/2” wide, the depth of the sealant should be equal to the width but not less than 1/4”. In joints wider than 1/2”, the depth should be maintained at 5/8”. Lap shear joints should have a width of at least twice the anticipated movement.

Joint Backing:
Joint depth should not exceed 5/8”. An open cell backer rod should be used to control joint depth. In shallow joints, a bond breaker tape should be installed to prevent three point contact.
Service Temperature:
– 40°F to 150°F (- 40°C to 66°C)
Application Temperature:
– 40°F to 150°F (- 40°C to 66°C)
Application and Tooling:
Apply with conventional caulking equipment. Fill joints from the back to prevent voids and air pockets. If application temperature is below 40°F (5°C), precautions should be taken to ensure the substrates are completely dry and frost free. Immediately after application, tooling is recommended to ensure firm, full contact with the joint sides.
