Casting With Plaster

Plaster is an extremely versatile and inexpensive casting material which can be used for many different casting projects.
Items which can be made with plaster
Decorative Ornaments Christmas Tree Ornaments
Childrens plaster painting objects Frig Magnets
Aquarium ornaments Cake decorations
Picture Frames Wall Plaques
and much more!

We recommend the use of Casting Plaster as opposed to the other commonly available plasters such as Plaster of Paris as sold by hardware stores, Pottery Plaster as sold by ceramic studios and Dental Plaster.

Plaster of Paris is more of a builders utility plaster, Pottery Plaster is made to absorb the water in ceramic slip and while Dental Plaster could be used it is unnecessarily expensive.

We carry stocks of Casting Plaster in our factory at all times in the large 20kg size as well as re-packed smaller sizes and these can be found on our web store under the name "Moulding Plaster". Click here for more information.

Casting Plaster is designed to dry with a hard exterior surface to prevent chipping and to make it easier to decorate.

We have a detailed instruction sheet available on our website on how to mix and pour plaster moulds with Casting plaster. Click here to read this instruction sheet.

Heavy Duty Plasters

There are times when a heavier duty plaster is needed such as when casting objects which are handled often such as Chess Pieces. It is advisable to use one of the harder plasters or as they are correctly known gypsum cement. We stock several types of heavy duty plaster such as HydroCal and Hydrostone.


Plastic Plaster Moulds

Flat backed plaque style plastic plaster moulds (Plaster Molds)

Aldax Moulds manufactures one of the largest ranges of plastic hobby moulds ready to cast over and over.

These types of plaster molds are by far our most popular and are by far our biggest range. We manufacture these plaster moulds using 0.5mm PVC food safe plastic and as a result they are often used to cast chocolate into. We have a large range of chocolate shapes. We make all plaster molds carefully to ensure the that the plaster whiteware is easily released from the plaster molds, with designs suitable for plaster painting and many other decorative uses around the home.

The plaster moulds are made in 3 standard sizes as shown below and may be used for casting plaster, papier mache, chocolate or other food products.

Holding moulds straight and level during casting has always been a problem. Various methods have been devised over the years from setting the mould in loose cloth to holding it level in wet sand. None have been particularly satisfactory.

After considerable experimenting we have developed a mould holder which we call our "Level Caster". We have several sizes available to fit each of our standard plastic moulds.

Latex 3D Plaster Moulds

Plastic moulds have always had the limitation of not allowing the casting of figurines and objects with large undercuts. They have been fairly limited to flat backed plaque style items.

Latex 3D plaster moulds are flexible enough to allow objects to be cast of high complexity and containing undercuts.

Aldax Moulds also manufactures their own range of moulds which is one of the largest and we have teamed up with SuperCast Moulds of England to bring you the largest range of latex rubber moulds in the world. Our range also includes the worlds best chess set moulds imported direct from England.

How to Paint Plaster Castings

Plaster is extremely versatile as a casting material and once set it can be decorated in many ways including painting, marble effects, guilding with gold leaf and even patinas which can give an antique effect.

Once the plaster casting has set completely it can be easily painted with cheap and readily available acrylic paints. This allows children to paint their plaster castings with non-toxic classroom paints with minimal supervision.

Customers have always been asking us where to get their hands on good quality and inexpensive classroom acrylic paints and we have sourced large 2 litre bottles of the primary colours.

We have these primary colours available seperately or in packs at a discounted price. Click here for the packaged set of paints.

We also have a range of paint pumps to allow easy use of the paints and aprons.
