Mix
the sand & cement together in a cement mixer or suitable mixing
vessel such as a barrow or bucket. Add some water and the plasticizer
directly to the mix (do not add the full amount of water at
this stage). mixing thouroughly in a semi-wet state will allow
the plasticiser to add air bubbles to the mortar. Add more water
and mix vigorously until a creamy consistancy is achieved. Carry
out a quick test in the Point Master. You will soon become familiar
with the consistency required for easy use.
The
use of plasticiser in bricklaying mortar is standard practice
& not a special requirement of the Point Master.
Some
pre-mixed mortar products may require slightly more plasticizer
to be added, especially when mixed by hand.
2.
A step-by-step guide to using the Point Master.
1.
“Liven up” the mortar. A quick stir is usually sufficient.
2.
Partially fill the Point Master until you are familiar with
using it.
3.
Hold the Point Master just above the nozzle in one hand, place
the other on the “end” of the handle grip. Keep the point Master
out to one side of you (not in front of you).
4.
A slight twisting action of the handle whilst applying pressure
will help to encourage an even flow.
5.
Before each refilling, shake or gently tap out unused mixture.
6.
Fill the Point Master & use immediately, holding the nozzle
square to the joint (see below).
7.
Slightly overfill the joints with either a series of movements,
or a continuous sliding motion.
8.
For a raised or overfill joint, customise the sides of the nozzle
with a notch or a groove.
9.
Wash out periodically. Clean the tool thoroughly after use.
