2008 IMPERIAL
Remove old sealant that is not adhered.
Sealant that is secured need not be removed.
Dirty or damp surface areas will compromise
sealant effectiveness. Thoroughly clean and dry
the surface area before applying new sealant.
Lay masking tape around the area to be sealed
to stop sealant from spreading beyond the
desired area. Using a caulking gun, apply new
sealant as needed. Work the caulking gun in a
manner that will cause the sealant to fully adhere
to the applied area. Allow adequate cure time.
Roof air conditioners use a closed cell foam base
gasket and do not require sealant. The roof air
conditioners should be regularly inspected for
tightness at the four mounting bolts, one located
in each interior corner of the air conditioner
roof opening. Torque speci
fi
cation is 40 to 50
in/lbs. The base gasket should be compressed to
approximately a ½".
Acrylic Sealants:

thinners or ketone based solvents as these
chemicals can damage painted surfaces.
Con
fi
rm that surface is clean and dry before
a new application. Cut the tube at an angle
with the smallest usable opening. Avoid a
heavy bead. A little goes a long way. Wear a
disposable latex glove and use
fi
nger at a 45°
angle on beaded surface to smooth out product.
Keep rags or paper towels handy for clean up.
Use care when applying silicone and plan ahead
before applying. Look for obstacles that may
impede application.
