Set-up and Operation
3.
After filling tanks, dispense polyurea through manifold assembly watching
flow. An errant stream out of one or both sides of the manifold will generally
indicate that there is a restriction in the manifold and disassembly and
cleaning should be performed.
4.
If flow is even and equal, attach static mixing tip to end of manifold.
5. Dispense a small amount of material through the tip into waste container
to ensure thorough mixing in the tip. Then dispense small amount of
material onto cardboard or other disposable sheet to monitor cure. Allow
to set for 10-15 minutes or until significant cure has been achieved prior to
commencing. This will ensure proper ratio and cure of future material.
6. While waiting on test material to cure, remove static mixing tip and discard.
7.
Pump grease (white lithium supplied with pump) into fittings on manifold to
prevent cross contamination.
8.
Upon confirmation of test sample cure, install new static mixing tip.
9.
Install filler into joint of crack per product installation guidelines.
Work Interruption:
1. If work is stopped for short term (5 minutes or so, to move pump, etc.)
periodically trigger applicator wand to dispense material every 30-45
seconds to ensure material in static mixing tip does not set.
2. If dispensing is stopped for longer term (lunch break, etc.) remove static
mixing tip and discard. Pump Grease into fittings on the manifold as
described above. Upon commencement, re-install a new static mixing tip.
End of Day:
1. If possible, stop material placement when tanks are “nearly” empty
(material is down to within a couple of inches of the tank bottom). DO NOT
RUN tanks dry of polyurea or improper ratio and cure may result if one tank
empties slightly ahead of the other.
2. In case material is run to the bottom of the tank, remove static mixing tip
and dispense remaining material into a waste container until tanks are
empty and line sputters at the static tip.
a. Fill both tanks with hydraulic fluid to approximately 3 inches from the
bottom.
b. Dispense hydraulic fluid to purge the pumps and lines. Ensure some
