This application of RedGard
®
has proven to be very successful;
the key element is training on the equipment. The operator must
understand and be able to make adjustments to the system along
the way. If not, there will be loss of efficiency and time. The
second man on the team must keep the unit filled and assist the
operator with hose movement and equipment adjustments. This
is not a difficult operation to learn, and once a team is trained,
efficiency will increase.
Maintenance and cleaning of the equipment is essential. Periodic
cleaning of filters throughout the day and at final clean up will
eliminate problems with system clogs and down time.
Spray tip selection, pressure adjustments and hose length all
have a direct effect on the system. Replace tips after applying
every 20 units (100 gallons) of material (to maintain proper
spray patterns and coverage). The use of wet film gauges is also
recommended, to ensure that material application is not too thick
or thin.
