Liquid latex rubber is good for use almost indefinitely. However, this is subject to proper storage so that outside air cannot come into contact with the material. Simple precautions will help.

Latex rubber is a natural material that is derived from rubber trees. It is versatile and easy to use. You can use it to make molds and casts or even to create special effects. It is equally usable for making masks and thin skin props or toys as for coating tools or making materials waterproof.

The rubber is available in a liquid form and can be used directly without mixing with any solvent. Simply pour the liquid into the mold and pour it out again, dip the tools in the latex or apply successive coats to build up a thick layer of latex rubber. The latex will be tough, durable and tear resistant even when in contact with abrasive surfaces.

What’s more, liquid latex allows a sufficient window of pot time before it will start to set. You can work comfortably while you build up successive layers of latex on the model or mold.

The latex also has a long shelf life and can be stored for years. It will continue to deliver the same functionality and ease of use. However, it is important that the container should not be left open after use. In fact, latex rubber should be stored in an airtight container and kept away from direct sunlight. If the container is exposed to heat, the rubber inside will take on a pinkish tint. But this still does not affect its workability.

One rule of thumb is that the latex should never freeze as it will become unusable. Special care is required during the freezing winter months.

In case you find that the latex rubber has thickened for some reason, the mixture can always be thinned by adding water or household ammonia. The thinning agent should be added slowly while stirring gently. But do not thin the latex too much as it will weaken the strength of the material.
