Ensure that there is enough sealant to complete the current seam. Sealant should be dispensed into each seam at a
rate such that the seam is completely filled with adhesive but completed within the open time. Allow vertical seams
time to cure before completing horizontal seams.
If a seam cannot be filled by sealant in one pass, an initial filler can be applied, then a secondary application over the
top of the initial application once the initial application has dried. Weather-strip putty may also be used for larger gaps
prior to finishing the seam with sealant. After smoothing remove painters tap before the sealant fully cures. Any
excess adhesive on panels can be cleaned using a solvent dampened rag.
Preparation of Applicator
•
Remove the plastic nut from the outlet end of the sealant cartridge
•
Remove the metal retaining clip and the plastic plug in the outlet ports of the cartridge and discard
•
Load the cartridge into the dispense gun, ensuring that the plungers are lined up properly
•
The plungers need to be level at the start of each new cartridge prior to use
•
Prior to installing the mix tip, slowly advance the plungers until a small amount of material is equally dispensed
from each port
•
After leveling the plungers fit the plastic mix tip onto the outlet end of the cartridge and secure with the plastic nut
that removed previously ensure the a proper mix ratio is being dispensed
After all panels have been seamed, apply seam sealant to any other cracks, such as gaps within the window frame, along
the perimeter of air vents and outlets, or joints between the FRP panel and the ceiling frame.
