Artestone is a very pourable, plaster-like mass that cures to a very durable, snow-white material. It can be used for pouring figures and shapes when the desired final surface is one that is very smooth and porcelain-like. When cured, the material is, even in the case of thin walls, extraordinarily break and abrasion resistant – considerably more durable, it should be noted, than the usual MODELLING PLASTER. It is not, however, capable of achieving the durability that can be attained using acrylic-based casting and laminating materials like ACRYSTAL (which, by the way, looks a lot like this product).
Another positive attribute: When cured, Artestone is hydrophobic, which means that the material will not absorb any water. This feature allows you to place a poured figure in the garden if you like or hang your new relief on an exterior wall of your house or even employ your new, beautifully shaped bowl as a bird bath. And its not only birds that have nothing to worry about: this casting powder is completely safe for humans as well!
Moulded parts made from Artestone take very well to paint: we have had great success using TONING PIGMENT and PIGMENTS FOR ACRYSTAL GYPSUM/ACRYLIC RESIN for this purpose. After curing has occurred, you can work on your piece with all the usual mechanical methods like sawing, drilling and grinding. This casting powder can be used in moulds made of plastic, SILICONE, POLYUTETHANE or LATEX.
Treatment: Four parts Artestone is mixed with one part water. In doing so, the powder should be slowly stirred into the water with a STIRRING SPATULA. A mass is thereby formed that can still be easily poured – you should wait one or two minutes after mixing before actually pouring to allow enough time for any trapped air to escape.
Uses: Plaster is not only good for fixing broken bones but is a great material for many creative purposes as well. It can be used in model making or handicrafts either as a natural product (made from burned selenite) or as a recycled material (so-called REA plaster which comes from a flue-gas desulphurizing facility).
Treatment: Plaster will cure after only a really short working life of a few minutes. In doing so, temperatures of over 50 °C will occur. In liquid form, plaster can be poured into moulds like, for example, ones made of SILICONE RUBBER. Liquid plaster can be coloured by means of PIGMENTS or, subsequent to curing, painted with most commercial paints (including water-based paint).
Once plaster has solidified, you cannot make it pliable again by adding water because it will never become solid again. By adding cellulose paste (WALLPAPER PASTE) the setting time can be increased somewhat.
If you want to do additional work on a cured plaster piece you must soak the area with water. The plaster will then be amenable to reworking with the appropriate tool without the piece itself breaking. Once dried, plaster models can be sawn, drilled, filed, cut, sanded, etc. Before subsequently levelling out the surface with more material, the plaster should be made moist because otherwise the second coat will not hold.
