should I consider Aldax Moulds?
Aldax is a small family company that comes
from a background of 25 years as an importer, manufacturer
and wholesaler in the hobby ceramic industry. During
this period we developed expertise in a wide range
of mould making and mould making products.
With the downturn in ceramics due to the emergence
of China as a major exporter, we decided to concentrate
on developing a niche market in the broad field
of moulds and mouldmaking. Based on our prior experience
in helping people set up small ceramic businesses
we commenced developing this informational site
2 years ago. It is designed to assist the do-it-yourselfer
and small business people to take advantage of the
rapid strides being achieved internationally in
developing applications and markets for decorative
How do I order?
This web site gives you the information you need
to do that small job around the house or to consider
the prospect of adding to your income by entering
the decorative industry, be it part time or full
time. Select any mould or mould product on this
site and you will be taken back to our main company
site www.aldax.com.au to place an order. A single
click will bring you back so you can continue moving
seamlessly between the two sites.
does to it take to receive my order?
We manufacture all moulds and many of the back up
products to order and do not keep stock. This way
you receive a brand new plastic or rubber mould
made to your order, enabling you to receive maximum
life from the mould. We try to manufacture plastic
moulds in 1 - 2 days, rubber moulds in 1 - 2 weeks,
Concrete Plastic Moulds in 2 - 3 days and custom
moulds in 3 - 4 weeks, depending on the complexity
of the job.
manufacture plain moulds without designs?
Yes we have a comprehensive range of plain moulds,
square, round and hexagonal. They are available
in 300mm 400mm and 600mm sizes. Many of these can
be used for making mosaic stepping stones.
Can I colour the
Iron oxide can be added to the concrete mix before
casting into the moulds to give a permanently coloured
stone. Most colours available are in the red, brown
or yellow range. Use sparingly as most additives
to concrete have a tendency to weaken it. Too much
colour will vary the drying times or cause the paver
to be streaked or cause cracking or breakage. About
half a teaspoonful to a paver should provide a good
pastel coloured product.
The big advantage in using colour as an integral
part of the concrete mix is that the paver is coloured
right through. Subsequent wear or chipping does
not reveal a base grey concrete colour as a painted
finish would do. See Tech Tips for antiquing suggestions
to provide additional colour variations to your
Do I need
a mould release?
Concrete sticks to a mould after it dries and needs
a mould release or lubricant to enable it to be
removed from the mould cleanly. A light grade machine
oil is the most effective release. However the plastic
and rubber manufacturers warn us that continued
use of a petroleum based product causes a breakdown
over time of the plastics and rubbers used in the
concrete industry. For this reason we recommend
that a vegetable oil be used. Industrial castor
oil is best but peanut, canola or other oils work
The thinner the viscosity of the oil the better
as heavy oils seem to retain air and yield air bubbles
on the surface of the concrete. Wipe the mould out
with a T- shirt type of material to leave only a
thin film of oil in the mould. Excess oil clinging
to the surface of the concrete after curing makes
painting or antiquing almost impossible.
of concrete should I use?
In our mould instructions we recommend a sand and
cement mix for the smaller pavers but the use of
bags of ready mix sand and cement gives good results.
For larger pavers ready mix containing sand cement
and aggregate is to be preferred for added strength.
Pour the mix into the mould until 1/3 full and then
bounce the mould against your bench to remove all
the air bubbles. Continue this process until the
mould is full.
Paver manufacturers use mechanical vibrators to
achieve the same effect. The bouncing or wrapping
action in addition to removing air bubbles, moves
the larger pieces of gravel aggregate to the centre
of the mould. The finer parts of the mix such as
the sand, go down into the design of the mould.
Properly vibrated moulds will show no sign of rough
aggregate on the surface of the finished concrete
paver, thus spoiling its appearance.
