Liquid latex rubber lends itself well for both mold making and casting purposes. But there’s a lot more going on for this handy material and not everyone may be aware of the varied possibilities waiting to unfold.
Latex rubber is a multi-purpose use material if ever there was one! It can niftily be used for a multitude of applications even as artists are finding new and innovative uses for the same.
By now, all of us are well aware that this humble rubber is one of the least expensive mold making materials. Yet, it is famed for its durable and long-lasting properties. Being inherently tough and tear-resistant, latex molds will outlast molds made of other materials. Needless to say, it becomes the mold making material of choice!
But there is a lot more going for latex and not all artists may be aware of the finer details and applications. Such as:
- Liquid latex can be easily applied to vertical surfaces – like for making molds of architectural details where they are – without the latex running off. It does not even need to be thickened for such applications.
- Latex molds are usually used to cast plaster, polyester resin or urethane parts. They are also used to make masks, gloves and other thin skin products apart from faux foods. It also serve well for casting abrasive materials without any damage to the mold whatsoever.
- The molds will stay reusable for a long time to come.
- The same latex rubber is formulated in a less viscous form (more fluid) for use for casting purposes. This is usually cast in plaster molds.
- Casting latex is the staple product for creating special effects makeup in theatre, TV, movies, etc. An experienced hand can easily create realistic looking wrinkles, gashes and scars with latex.
- The same material is used for prop making in general. The simplest application is to carve foam in the desired shape before coating it with liquid latex. However, the surface cannot be expected to be perfectly smooth.
- What’s more, it can also be used as an adhesive for bald caps.
- There’s still more to come as liquid latex can be used as a dipping rubber. Simply dip the model in the latex a number of times to form successive coats. This technique can be used for creating a waterproof coating as well.
- Dipping tools in liquid latex will form a coating that not only makes them comfortable to use, but also insulates them from electrical hazards.
- The degree of flexibility of latex casts can be controlled by adding an appropriate filler.
Note of Caution
Always keep in mind that:
- Liquid latex has a good bit of alcohol mixed in it.
- Regular paints and dyes do not work well with latex as they will tend to crack and chip. Specially formulated latex dyes are compatible with latex casts.
- Liquid latex should never be allowed to be frozen. Store it carefully in cold temperatures, as once frozen, it becomes unusable.
