DURO-GRIP BOARD-MAX INSULATION ADHESIVE
®
ORDERING BOARD-MAX:
1. The following items are available when ordering.
a. A/B Tank Kit. (Item #11035)
Each kit includes:
 “A” & “B” Tanks
 Hose/Gun Kit
 8 Nozzles
 Wrench
 Installation Instruction Sheet
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 75 – 85˚ F (24 – 29˚ C) and the
surfaces being bonded should be between
30˚ F and 100˚ F (-1 – 38° C). Temperatures
outside this range may affect bonding range,
dispensability and performance of the
adhesive.
2. Equipment Set Up:
a. There are two tanks per system: an “A” tank
and a “B” tank that are both beige. These two
tanks must have matching fill dates to be used
together.
b. Shake the tanks for 1 to 2 minutes. Turn the
tanks upside down at least twice to ensure
complete agitation of the adhesive.
c. The tanks can only be used in the upright
position (never open the valves unless the
tanks are upright).
d. The lids on the boxes are designed to shield
the tanks from direct sunlight and keep the
adhesive from getting too hot. For this reason,
the box lid should remain closed during use.
e. Using the wrench included in the nozzle pack,
connect the RED striped hose to the “A” tank.
f. Connect the BLACK striped hose to the “B”
tank.
g. Slowly open the tank valves and inspect the
connections for any leaks. Tighten if needed.
Fully open the valves.
h. 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.
i. Clean residue from the output tips.
j. 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 1/2 to 3/4 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 30 seconds, 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 minute. If the
trigger is pulled while a clogged nozzle is on
the gun, the chemical from the tanks (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 the nozzle when spraying is stopped
for more than 30 seconds.
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. Apply adhesive in a serpentine
pattern. Nozzles are temperature-activated.
If nozzles turn blue, then adhesive is too
cold to apply. Adhesive must be warmed
up prior to proceeding.
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
