The CHT733 Brick Mortar Gun can be used as a mortar or tile grouting gun
and can be used for jobs such as re-pointing walls, filling gaps in patio slabs
and grouting floor and wall tiles.
When using the gun for re-pointing and filling gaps in patio slabs etc, it is
important that the correct mix of soft building sand is used.
Ensure the mix is lump-free and is of a smooth, creamy texture. The use of a
plasticiser is recommended.
Do not use sharp sands or gravels.

2. Insert either a straight or angled
nozzle into the opening of the
ring.
3. Screw the ring back into the body
of the gun as in Fig 2.
When working with ready-mixed
grouts, ready mixed tile adhesives or
ready-mixed fillers use the tapered
nozzle as follows:
1. Unscrew the end retaining ring
from the body of the gun.
2. Insert tapered nozzle (Fig 3) and

Fill the gun with mix as follows:
1. Unscrew the trigger end of the
gun from the body and withdraw
the trigger assembly and plunger.
2. With the scoop provided, fill the
body with the correct mix of
mortar to within 3 cm of the top
as shown in Fig 5.
3. With the plunger fully retracted as
shown in Fig 6, attach the trigger
back onto the gun body by
screwing the ring clockwise until
finger tight.
Your mortar gun is now ready for use.
OPERATION
1. To use, simply squeeze the trigger
with a steady pressure. To stop the
flow at any time, push the trigger
plate forward with your thumb, as
shown in Fig 7 and withdraw the
plunger slightly.
• If mortar does not flow, it could
be that the mixture is too dry,
lumpy, or that something other
than soft sand has been used, or
that the mixture has started to set.
• If this happens, you will need to start again, ensuring the mix is correct and
that the interior of the body and nozzle are clean and free from any dry
mix or other obstruction.

2. For working with patio slabs or floor tiles, use the angled nozzle and hold
the mortar gun at 45º to the work as you apply the mix.
• To withdraw the plunger, push the
trigger plate forward and pull the
rod backwards until it is fully
retracted as shown in Fig 8.
• If using powdered grouts and
powdered fillers, ensure you mix
to the manufacturers instructions
and ensure the mix is free from
lumps and is a smooth, creamy
texture.
• Do not allow the mix to be too
wet as this will flow uncontrollably from the nozzle. Likewise, making the
mix too thick will block the nozzle.

MAINTENANCE
1. After use, wash all parts immediately in clean water, ensuring all the mix is

• A spare plunger end, which may occasionally need replacement, is
included with your mortar gun. To replace it proceed as follows.
2. Hold the retaining nut below the
plunger end with a suitable 14mm
spanner as shown in Fig 9.
3. Turn the cup containing the nylon
plunger end anti-clockwise.
4. Remove the metal cup and nylon
plunger end with nut from the
plunger as shown in Fig 10.
5. Refit the nut into the hexagonal
opening in the replacement
plunger end.
