22 Mortar consistency
The processing-related properties of the mortar are improved by
re-stirring following the pumping and the longer dwell time in the
mixing zone.
The correct consistency is reached, if the material mixes on the
surface to be sprayed (preferably apply on wall surfaces from top
to bottom). If the water quantity is too little even mixing and
spraying is no longer guaranteed; blockages may form inside the
hose and high wear of the pump parts will become an issue.
23 Interruption of work or end of work
The break duration (machine standstill with mixed material) is
determined depending on the respective mortar. If a remixer is
attached, the break times must be reduced by approximately 1/3 to
avoid settling of the mixing impeller. In case of a longer standstill,
the remixer must be dismounted and cleaned.
Longer breaks should be avoided as otherwise there is a risk that
the mortar will solidify in the pump, remixer and the hoses.
NOTE!
The guidelines of the material manufacturers have to
be observed regarding breaks.
It is advisable to clean the pump before longer
interruptions.
NOTE!
Any interruption of the spray operation results in a
slight irregularity in the consistency of the
material.This irregularity normalises by itself as
soon as the machine has been working for a short
while.
Therefore it is important not to change the water
quantity for each irregularity.Wait until the
consistency of the material has been set again.
