Assemble the mortar set and place the injection cartridge
into the applicator gun.
Expel a 10 cm length of mortar or two full presses of the
gun until the mortar has an even grey colour. This material
must be discarded. Insert the extension tube to the bottom
of the drill-hole. Draw the applicator gun slowly back out
of the drill hole during the fi lling process allowing
the pressure of the mortar to determine the
exiting speed. Inject about 11 ml mortar in
each drill hole. Observe the processing
and curing periods in the table below.
