Using Liquid Latex Casting Rubber

EnvironMolds Premium Latex Casting Rubber is a consummate liquid latex formulation that serves well for varied applications. It can be used to make masks and other hollow items with different methods.

Liquid latex rubber is a popular material in the world of mold making and casting. It is tough, durable and tear resistant, apart from being an economical product. It is commonly used to make different types of molds for casting plaster, resin and other materials. The same material can also double up as a casting product, albeit in a less viscous form.

In fact, latex casting rubber is a popular theatrical product to create special effects like wrinkles, scars and gashes. It is also used to make all kinds of masks and other thin skin products.

EnvironMolds Premium Latex Casting Rubber is an exceptional casting rubber specifically formulated for making hollow molded rubber articles, toys and flexible props. It lends itself well for making masks, puppet heads, imitation pottery and display articles. It is especially useful for creating general special effects for film, television and stage work. Furthermore, the same product is considered appropriate for coating and texturing foams such as polystyrene, especially for special effects applications.

The liquid nature of latex casting rubbers makes it very easy to use. Pouring or painting are the common methods of making latex casts. All it takes is successive coats of the latex over or inside the mold to make the hollow or thin skinned rubber items. It is useful for making gloves, fake food and other such items.

On the other hand, artists usually pour the latex casting rubber directly into the mold. The mold is filled till the brim and the latex is allowed to sit for some time post which the rubber is poured back into its original container. A thin layer of latex clings to the sides and base of the mold. This sets like a skin overnight and can be demolded easily. This method is commonly used for making masks.

Apart from this, you can also simply dip the mold into the latex to form a coating. Each coat has to be allowed to dry before dipping again to build up the required thickness. In fact, EnvironMolds Premium Latex Casting Rubber serves well for dip casting and can be used to form a protective coating on tools.

These latex casts cannot be finished with regular paints as it will tend to chip, crack or peel away. Special latex paints and dyes are available. These can be added to the rubber before starting the casting process or painted on the cured surface later on.

Moreover, you can also use a filler and extender like RubRfil to control the level of flexibility of the latex rubber cast. In case the liquid latex is too viscous for a particular application, mixing the requisite quantity of RubRfil will thicken the rubber and render it less flexible, hard or even very hard. This also serves to extend the quantity of the material.

How To Make A Front Torso Cast

 Making a front torso cast can seem intimidating at first. However, it is the easiest life casting that can be tackled by beginner life casting artists as well. Let’s find out what lies in store….

A front torso casting can seem like a tall order because of the bigger dimensions involved. However, this is one of the easiest life castings as the body surface from neck to mid-section will be broad and mostly even, with hardly any undercuts. In fact, novice life casting artists often prefer to begin with torso casting before moving on to more complicated life casts like face and full body.

Yet, care is required when working on a living, breathing person. The model should be carefully briefed about what lies in store and warned about the issues like staying stationary, application of mold material, mold getting entangled in the body hair, waiting for the mold to set and so on.

The key to making a good torso cast lies in the posing. The model has to pose in a standing position, preferably propped up against a board or the wall for support. The pose can be a slightly leaning one to reveal the muscle tone, arms spread-eagled or on the sides of the waist. Women usually prefer to pose with hands on their breasts or encircling the belly in case of a pregnancy casting.

Once the model has been prepped, the body mold making process begins with applying petroleum jelly or other release agent all over the torso. Then apply a couple of layers of the alginate mix to form a thick and even coat. This alginate is skin safe and will not harm the model or the artist. It sets quickly and will capture all the fine details as well.

Once the alginate mold has set, it is covered with plaster bandages. The bandages are soaked in water and squeezed before applying on the alginate mold in a crisscross fashion. This will form a shell mold that supports the alginate and helps it retain the shape.

Allow the plaster mold to dry properly. Once it has set, the body mold can be easily demolded by loosening the edges with the fingertips. It will lift away easily and can then be cast with plaster or other choice of casting material. The casting should be done quickly as the alginate is likely to shrink on exposure to air.

There is a choice of making faux metal or stone life casting also by using the appropriate cold casting powder along with the casting material.

In sum, it is pretty easy to make a front torso life casting. It will take time and patience, but the artist will get better with practice. For further ease, EnvironMolds offers the comprehensive Front Torso Casting Kit. This contains the appropriate quantities of alginate, plaster powder and plaster bandages along with mold release, gloves, sandpaper and a handy instruction booklet as well.

The website, also throws up a helpful ‘How To Create A Front Torso Casting’ book. This how-to manual provides necessary instructions about the materials, preparations and techniques as well as tips for preparing the model, demolding and finishing the life cast. A model release form is also included.
