Installation Guide
For Vertical outside Corners, repeat process steps 1-8 as listed in Vertical Flat Panel Seams
VERTICAL INSIDE CORNERS
1. Repeat process listed in Vertical Flat Panel Seams except for the format to smooth the sealant
2. Smoothing the Sealant
A. After the sealant has been dispensed, smooth the sealant beads flush with the panel
surface using the Radial Seam Finisher if a rounded corner joint is desired.
B. The Inline Seam Finisher can also be used if a flat inside corner bead is desired.
C. Finishing/smoothing tools and techniques to be at the discretion of the operator and/or
the end user.
D. Smoothing of the sealant must occur within the open time of the sealant.
E. As soon as the smoothing of the sealant is complete, remove the painters tape. Any
excess sealant on panels can be cleaned using a solvent dampened rag.
HORIZONTAL FLOOR AND CEILING JOINTS
1. Material should be dispensed into each seam at a rate such that the seam is completely
filled with sealant but completed within the necessary open time for the sealant.
2. It is recommended to pull dispensing gun away from bead during application.
3. Ensure vertical seams are cured prior to processing horizontal seams.
4. It is also recommended that operators ensure that there is enough sealant in the
cartridge to complete a full seam. Performing a cartridge change in the middle of a seam
application could increase the risk of exceeding the open time of the sealant.
5. If the seam has a large gap and/or cannot be filled by the sealant in one pass, an initial
“filler bead” can be applied and then a secondary bead can be applied over the top of
the initial bead after the initial bead has reached full cure. Mechanical filler, such as
weather-strip putty, may also be used to fill large gaps prior to the application of the
urethane sealant.
6. Smoothing the Sealant:
A. After the sealant has been dispensed, smooth the sealant beads flush with the panel
surface using the radial seam finisher if a rounded corner joint is desired.
B. The inline seam finisher can also be used if a flat inside corner bead is desired.
C. Finishing tools and techniques to be at the discretion of the operator and/or the end
user.
D. Smoothing of the sealant must occur within the open time of the sealant.
E. As soon as the smoothing of the sealant is complete, remove the painters tape. Any
excess sealant on panels can be cleaned using a solvent dampened rag.
