c. Extra Nozzles, bag of 10 (Item #1109-002)
Directions for Use:
1. Application Surface and Temperatures:
a. For best results, all surfaces to be bonded must
be clean, dry and free from dirt, dust, oil, loose
paint, wax or grease, etc.
b. The temperature of the adhesive should be
between 70 - 90 ˚F (21 - 32 ˚C) and the surfaces
being bonded should be at 40 ˚F (4 ˚C) or above.
Temperatures outside this range may affect
bonding range, dispensability and performance of
the product.
2. Equipment Set Up:
a. There are two cylinder tanks per system: an “A”
cylinder that is RED and a “B” cylinder that is
BLUE. These two cylinders must have matching
fill dates to be used together.
b. The cylinders can only be used in the upright
position (never open the valves unless the
cylinders are upright).
c. The lids on the boxes are designed to shield the
cylinders from direct sunlight and keep the
product from getting too hot. For this reason, the
box lid should remain closed during use.
d. Using the wrench included in the nozzle pack,
connect the RED striped hose to the “A” cylinder.
e. Connect the BLACK striped hose to the “B”
cylinder.
f. Slowly open the cylinder valves and inspect the
connections for any leaks. Tighten if needed.
Fully open the valves.
g. Activate the trigger, dispensing into a proper
waste receptacle, until all the air is released from
the hoses and a good stream of both chemicals is
visible through the applicator orifices.
h. Clean residue from the output tips.
i.
Attach the mixing nozzle to the applicator. Insert
the bottom tab of the nozzle into the bottom slot
of the applicator gun. Secure the top latch by
pushing towards the back of the applicator until it
“snaps” into the locked position.
3. Adhesive Test Spray:
a. When spraying for the first time or when starting
a new kit, it is recommended to trigger the gun
only ½ to ¾ open, until the desired output and
spray pattern is achieved. This controllable
metering ability is a major advantage of the gun,
allowing the user complete control of the flow rate
and spray pattern that best fits the application.
b. Apply several test shots on plastic or cardboard
before beginning the job.
c. Extremely Important - When spraying is stopped
for more than 1 minute, the nozzle should be
removed and replaced with a new nozzle. The
chemical in the nozzle will begin to cure and will
clog the nozzle when spraying has stopped for
more than a few minutes. If the trigger is pulled
while a clogged nozzle is on the gun, the
chemical from the cylinders (which is under
pressure!) will be blocked by the clogged nozzle
and will cause a “back-up” of chemical into the
hoses, which is called a crossover. The gun will
no longer dispense chemicals in the right
proportions and the adhesive will not function
properly. This situation can be easily avoided by
simply changing nozzle when spraying is stopped
for more than 1 minute.
4. Adhesive Applications:
a. To dispense foam, point the applicator’s nozzle at
the surface to be sprayed, holding it
approximately 20 inches from the surface.
Squeeze the trigger and move hand at a speed
which delivers the desired adhesive pattern.
b. Refer to the "Determining Bead Spacing" section
for the spacing between beads.
c. Insulation boards are to be placed immediately
on the wet adhesive but not walked-into-place or
compressed into the adhesive until the adhesive
has begun to thicken and has started to develop
its initial bond.
d. The time involved in this process is contingent on
the ambient as well as deck surface temperature.
The chart below illustrates the approximate time
required prior to walking in or adding ballast to
the boards.
Ambient / Deck Temperature Time Before Walking In
40 - 60 °F 6 - 10 minutes
60 - 80 °F 3 - 6 minutes
80 - 100 °F 1 - 3 minutes
