The Many Faces of Liquid Latex Rubber

Posted by EnvironMolds , Labels: , , , , , Sunday, April 23, 2023 6:07 AM

Liquid latex rubber is in a class of its own with a broad range of artistic applications that are not just limited to mold making and casting. It occupies a special place in the world of masks and special effects.

Liquid latex rubber is like the Holy Grail of artistic applications. This fluid material is easy to use and can be used for different purposes. It proves to be flexible, tear resistant and displays exceptional tensile strength across its varied range of applications. It is not only durable but also economical as compared to other mold making and casting materials.

Let us take a look at some of the uses of latex rubber:

  • Molds – Liquid latex can be easily used to make molds of different objects. It will capture details well and can even be applied on vertical surfaces – like architectural details – without it running off. Anything from plaster to urethane or polyester resin can be cast in the latex molds to make figurines, moldings and the like.
  • Casts – What sets casting latex rubbers apart from their mold making counterparts is that they are less viscous. The casts turn out to be like a thin skin, making it perfect for making props, gloves, hollow toys and the like.
  • Mask making – Liquid latex rubber is most identified with making masks. It is the first choice for making different types of masks that replicate the contours of the face to the last detail. It can be finished with monster, zombie or other spooky effects.
  • Costumes – The same rubber is also used to make customized costumes for Halloween and other occasions.
  • Special Effects – Name any kind of special effects on the body and liquid latex can be used to create the same for film, television and theatre productions. Realistic looking wounds, gashes, scars and other effects become possible in the hands of an experienced artist. Many people use it for body painting and even nail art.
  • Protective Coating – Latex rubber is used to form a protective coating on tools and other surfaces. Simply dipping the object in the liquid latex a couple of times (while allowing each successive coat to dry in between) will render a better grip and comfort in usage apart from providing electric insulation.
  • Waterproofing – Dipping a material in liquid latex will make it waterproof after curing. This is usually used for making raincoats and rubber boots that will not allow water to seep through them.
  • Repair Jobs – Pouring a bit of liquid latex serves well for covering up holes and tears in certain fabrics.
 
When it comes to making a choice of liquid latex rubber, RD-407 Mask Making and Casting Latex is useful for all the above purposes. It remains the prime choice for making a latex mask.

In sum, there’s not much that cannot be done with liquid latex. The humble material is easy to use – as simple as pouring it into the mold or dipping the model into the rubber!

The How To’s of Latex Molds and Casts

Posted by EnvironMolds , Labels: , , , Wednesday, March 1, 2023 10:00 PM

Latex rubber is a versatile material that lends itself well for different uses. It is relatively easy to make latex molds and casts, though the processes vary a lot. Find out more about them right here.

Liquid latex rubber is an impressive rubber that finds varied applications on both the mold making and casting platforms. The rubber forms a thin and flexible skin which is used to make different items like gloves, swimming caps, rubber bands, balloons, catheters and other hollow-molded objects. The most common application is in making props apart from regular things like mattresses, tennis shoes and other sporting goods. The same latex finds its way into chewing gums and even serves well as an adhesive for bald caps. Not to mention that latex rubber is widely used as a special effects product to create wrinkles, scars, gashes and other simulations of injury, age or non-human characteristics for television, movies and theatre. The rubber lends itself well for making a latex mask which is popularly used for Halloween!



How to use?


One of the best parts about working with one of the most economical, resilient, versatile, tough, tear resistant and durable materials, latex rubber, is that it can be used to make both molds and casts. The mold making variations are generally more viscous than their casting counterparts, however, experienced artists even use them interchangeably.

A latex mold is usually made by painting the rubber on the model. This is a slow and lengthy process as it requires a good number of coats to build up the required thickness while allowing sufficient time for each subsequent coat to dry. This rubber can even be applied on models where they are, without the worry of the material running off the vertical surface. These molds can be used to cast plaster, polyester resin or urethane parts.

When it comes to latex casts, they are usually made in plaster molds. The process is quite simple and straightforward. Fill the mold with the rubber and allow it to sit for around 15 to 20 minutes before pouring off the excess back into the container. A thin layer of latex will remain in the mold. The plaster will slowly suck the water from the rubber, thus creating a latex ‘skin’, around 1/8th inch thick, inside the mold. The mold should be left as it is overnight or so for curing. The latex cast can be demolded after dusting the inner surface with talcum powder so that the latex does not stick to itself.

This is how latex masks are usually made. In case numerous copies of the cast have to be made, it is prudent to first make a master copy with rubber. This is because plaster molds tend to wear quickly. The master can be used to make subsequent plaster molds for repeated use.

The cured and demolded latex rubber cast can be finished using special latex dyes and paints before being used as desired.

All About the Mold Making and Casting Materials

Posted by EnvironMolds , Labels: , , , , , , Wednesday, October 26, 2022 10:59 PM

 There is a broad range of materials that can be used to make molds, casts and life casts. Check out some of the options available along with their varying properties and usage in the world of artwork.


EnvironMolds is home to a complete line of mold making and casting materials along with the requisite supplies, tools and equipment. Quality is always a top priority for this leading art supplier which actually makes a difference in the molds, casts and life casts.

Let us take a look at some of the commonly used products:


Latex rubber: Liquid latex rubber is an economical material that is easy to use as well. The molds turn out to be tough, durable and tear resistant. A slightly less viscous form of the rubber is suitable for casting purposes as well. In fact, latex casting rubber is regularly used for making masks and other special effects for films and stage.



Silicone rubber: This is a more expensive rubber but the efficiency and applications more than justify the price. Apart from regular silicone rubbers, there are special formulations for using on the human body, on food items and even for doll reborning. This rubber is again versatile and can be used for making silicone casts as well.

 




Resin: This family comprises of polyester, epoxy and polyurethane resins that come with their own set of properties and usage. Generally speaking, polyurethane resins are most preferred for making casts. This material lends itself well for cold casting that can replicate the look of different metals, stones, wood, etc.

 




Clay: Clay is a versatile material if ever there was one. It comes in different types and is suitable for a range of mold making applications apart from other minor uses like sealing edges, making mold boxes and so on. However, artists prefer plasticine to regular clay for molds.

 



Alginate: This dental impression material is not only safe for the skin but also captures details well. It is the material of choice for making body molds for life casting. Varying set types and times are available to suit different applications. But the molds are good for one-time use as they tend to shrink and have to be used quickly.



Moulage: This is a reusable mold making material that is heated to melt before use. The mold can be remelted and reused again and again. It is skin safe too.



Wax: This is a simple material that can be modeled, carved and cast as desired.



Plaster: This white powder can be mixed with water and used to cast objects. It is widely preferred for life castings. However, regular plaster of Paris is better avoided as it tends to get chalky and flaky over time. Plaster-embedded bandages are also available that can be used to make shell molds to provide support to flexible rubber molds.



Apart from latex rubber and other materials, the ArtMolds website also stocks release agents, fibers, fillers, cold casting powders and more.

What You Need to Know About Latex Casting Rubber

Posted by EnvironMolds , Labels: , , , , , Thursday, August 11, 2022 4:29 AM

Latex rubber is fun to use and lends itself well to varied projects. It can be used by beginners as well as experienced artists. It is fun to play around with the rubber with unending creative possibilities.

Liquid latex rubber can be split into two categories – mold making and casting rubber formulae. While the purpose is obvious from the names, it should be noted that liquid latex casting rubbers are always less viscous than the mold making ones. Therefore, they are preferred for making props, masks and other theatrical work.

As this category of rubber is more fluid, making the cast is as easy as pouring the material into the mold and letting it sit for some time before pouring it out again. This forms a thin skin inside the mold – the perfect way to make stretchable masks, props and other thin rubber items. RD-407 Mask Making and Casting Latex is the preferred product for such applications.

The same latex can be applied on the skin to create varying kinds of special effects. It will dry quickly to form a second skin of sorts, making it perfect for creating gashes, wounds, cuts and even horrifying effects.


Working with latex rubber


Latex rubber compounds are very easy to use as they do not require any mixing or other preparations. Application is direct and simple and the molds/casts capture excellent details to create an exact reproduction.

Latex casts are inherently flexible, more so than the casting formulations. However, the degree of flexibility of the latex cast can be controlled by adding an appropriate filler. RubRfil Latex Mold Rubber Filler And Extender is an excellent product that can make the latex cast turn out to be very flexible or very hard depending on the combination. The following proportions are suggested to get varying results:

  • 1 part latex to 1/2 part RubRfil - very flexible
  • 1 part latex to 1 part RubRfil– flexible
  • 1 part latex to 1 1/2 part RubRfil - medium flexibility
  • 1 part latex to 2 1/2 part RubRfil - very hard

The versatility of latex casting rubber comes to the fore when it is used for dipping and coating purposes. Fabrics can be dipped in liquid latex to make them waterproof. The same coating can also insulate tools from electric hazards. Apart from the protection, the coat also improves grip and comfort during usage.

Latex rubber usually has a transparent or white finish. It can be colored using special paints and dyes as the regular ones tend to chip and crack easily. These can be used intrinsically by mixing in the latex rubber or be painted on the cured latex surface. Varying shades are available.

When it comes to storing the liquid latex casting rubbers, both the material and the molds/casts have a long life and extended durability. However, keep in mind that liquid latex has a fair amount of alcohol mixed in it and should be handled with care. It should be stored in airtight containers and kept away from sunlight.

What You Need for Mold Making and Casting

Posted by EnvironMolds , Labels: , , , , Friday, July 22, 2022 2:16 AM

Making molds and casts involves a range of materials, supplies and equipment. Following is a look at the different items that should be kept at hand before beginning a mold making or casting project.

Mold making and casting are intricate arts that require different materials, supplies, tools and equipment. A lot of details are involved in these processes and it calls for careful and precise usage of the procedures as well.

To begin with, there is a choice of a variety of materials like clay, wax, plaster, alginate, liquid latex rubber, silicone rubber, polyurethane resins and more. The selection depends on the technique, artist’s dexterity and preference. The common tools and supplies range from brushes, spatulas, gloves and containers to knives, rasps, scalpels, pliers, calipers, etc. In case the materials involve an element of risk to the artist, it is advisable to wear protective equipment like gloves, goggles, mask and coat. Some even use a respirator to prevent inhalation.
 
The mold making usually starts with a mold box and a base plate. The master model is either placed in the mold container or secured to the base with clay or a suitable adhesive. A sealant may be required if the model has holes or happens to be porous. Applying a thin coat of an appropriate release agent is usually recommended as it will help in easy demolding.

Again, depending on the mold making material, it may have to be degassed using a vibrating table, pressure pot or vacuum chamber with pump. This will eliminate air pockets in the material which show up as unsightly bubbles in the mold.

Once the mold has cured properly, the demolding process can involve cutting the mold with a sharp knife, scalpel or using other tools to extract the model from the mold. The mold is smoothened using certain specific tools before it is ready for casting.

In case the mold is made in two or more parts, it will require placing keys that facilitate an easy coming together of the mold parts. If the mold is very flexible, it may even have to be reinforced with a shell mold that is generally made with plater bandages.

The casting process usually begins with applying a release agent on all the surfaces of the mold to ensure easy demolding later. The material may also have to be degassed before pouring into the mold. Once the cast has cured, it is extracted using tools and finished as required.

The cast can even be painted to create the desired effect. Some rubbers and resins require special paints and dyes as the regular ones are not compatible with these materials.

Last but not the least; all the materials, supplies and other requirements – like say, latex rubber, silicone rubber, scalpel, mixer and vacuum chamber – should always be sourced from a established and reliable source to ensure that everything is of top quality and will work as expected. This will ensure best results in the mold making and casting.

Effect of Temperature on Mold Making and Casting

Posted by EnvironMolds , Labels: , , , , Wednesday, November 10, 2021 2:15 AM

Temperature can play havoc with the curing of molds and casts by delaying/accelerating the process or not allowing the material to cure at all. Knowledge of the properties will ensure better results.

It is not just about the technique or dexterity of the artist; the quality of the mold or cast is affected by many other characteristics as well. Temperature plays a starring role here – ranging from the temperature and humidity of the surroundings to even the warmth/coldness of the material and model/mold.

This is why it is always recommended that all rubber and resin compounds should be stored at room temperature (72°F/23°C). For instance, if a material is stored at elevated temperatures, like in a hot garage or in direct sunlight, both the shelf life and pot time will get reduced drastically. In contrast, if latex rubber freezes, it becomes unusable and has to be thrown away. Other frozen materials can still be used after they are brought back to room temperature.
 
Let us take a look at how the temperature factors can affect the making of molds and casts:

Cold – A cold environment will usually prolong both the working time and cure time of most materials like epoxy resins, urethane rubbers and platinum cure silicones. The evaporation process of latex rubber also gets delayed in colder temperatures. In case the environment is too cold, some of these materials may even fail to cure at all. However, tin-cured silicones are not as dramatically affected by colder temperatures.

Heat – The opposite is also true as higher temperatures are known to accelerate the cure time and most materials tend to cure much more quickly when it is hot. In fact, many artists deliberately apply heat to hasten the curing process. However, tin-cured silicone rubbers are again an exception as they are not as affected by heat and cannot be ‘heat cured’.

Humidity – Rubbers are best used in a low humidity environment. Higher humidity tends to accelerate the curing in tin-cured silicone rubbers while it has the opposite effect of slowing the evaporation and curing process in latex rubbers. Making molds or casts of urethane rubbers, plastics or foams in humid environments can cause bubbles or foaming in the material. However, platinum-cured silicones and epoxy materials are not affected by humidity.

In addition to this, if the model that is being used to make the mold happens to be too cold, the curing of the mold will take unnecessarily longer to cure and vice versa. Therefore, the model/mold should be brought to room temperature prior to use. When making a mold of a frozen model, it will start condensing once the mold material is applied which will in turn delay the curing. This is why it is better to use accelerated silicones as they will not be affected by the moisture.

Finally, good quality liquid latex rubber, silicone or epoxy materials can be easily sourced from EnvironMolds at https://www.artmolds.com/ at the most reasonable prices.

Working with Mold Making Latex Rubber

Posted by EnvironMolds , Labels: , , , , , Friday, September 10, 2021 4:45 AM

Latex rubber molds are easy to make, economical, last for years and can be used for multiple castings. Following are a few pointers to be kept in mind when making a latex mold through the brush-on method.

Latex rubber is considered the best material for making molds – it trumps in terms of affordability, durability, reusability, convenience and more. The molds turn out flexible and can be used to capture a negative impression of statues, figurines, plaques, life castings, etc. The most complicated models can be easily captured down to the minutest details.

In fact, latex is formulated in liquid form to allow ease of use for making molds. Take Kreemtex Premium Liquid Latex for Mold Making for instance. The liquid rubber can be brushed, sprayed or poured over the model to capture its shape in a mold. The thick consistency makes it easy to apply and also allows for easy coverage with minimum coats. However, if the rubber seems to be too concentrated, it can be thinned to a more viscous consistency by adding distilled water to get the requisite runniness.

Latex rubber should be stored in a cool place; it should not be allowed to freeze as this will make it unusable. It should be stirred properly prior to use. In case the ammonia content of the latex has evaporated or diminished over time, it is better to replenish the same before use. However, the ammonia should come from a chemical store and not grocery ones as the latter contain more of soap. Add a bit of ammonia at a time till the original texture is obtained.



How to apply?


Brushing multiple coats of latex over the model is the most common method of making a latex mold. Some models may have to be sealed prior to late application. Applying a suitable release agent is preferable.

Start from the top of the model and brush the latex in a thin and even coat while making sure that all air bubbles are brushed out. From the bottom, continue out to form a two inch flange which will serve handy when using the mold for casting.

Allow each coat to dry properly – it should be dry to the touch - before starting the next one. Here it is advised to apply the liquid latex in a checkerboard fashion by alternating the direction of application. This will ensure that the mold does not shrink and the dimensions do not change. A heat source can be used to hasten up the drying between coats.

Once the desired thickness is built up (will take 10 to 12 coats at least), the mold can be removed from the model and allowed to dry further for 72 hours or so. Curing in a warm atmosphere to ensure proper strength and toughness to the mold.

Molds made from Kreemtex Premium Liquid Latex for mold making will be stable, tear resistant and can be used to cast different materials. The outcome will be perfect as long as the proper procedure and precautions are followed!

The Ins and Outs of Latex Rubber

Posted by EnvironMolds , Labels: , , , , , Wednesday, March 31, 2021 4:29 AM

Latex rubber is an artist’s weapon that can be wielded in varying manners. The properties and versatility of liquid latex rubber are to be experienced to be believed. Let’s find out more about this….

Liquid latex rubber is a versatile product that lends itself well to varied applications. The wonderful part about the rubber is that it is suitable for making both molds and casts. Changing the viscosity will change the application – latex molds require more thick and viscous formulations than casts. The degree of flexibility of the latex can be further controlled by adding an appropriate filler during the casting process.


Latex mold rubber is commonly used for mold making as it is economical, durable and easy to use. The molds will be tough, tear resistant and can be reused multiple times. They are used to cast plaster, polyester resin, urethane and even abrasive materials like concrete.

On the other hand, the casting variant of latex rubber is used for making hollow molded rubber articles like toys, balls, props and even display articles. It enjoys great patronage for making masks, puppet heads and even special effects like wrinkles, scars and gashes for theatrical work.

Latex rubber can be brushed, sprayed, poured or dipped for making the molds and casts. Brushing requires successive coats and sufficient time should be allowed for drying between each coat. This process is continued till the desired thickness is obtained. Spraying will also involve a similar process.

Latex is usually cast in plaster molds because of the porous nature of plaster. When the rubber is poured into the mold, the plaster sucks the water out and leaves a thin latex skin behind. Slip latex casting is a commonly preferred method as it is comparatively easy and does not leave any brush marks either.

When it comes to demolding the latex mold or cast, an easy trick is to dust the latex with talcum powder before peeling it off slowly. The powder will keep the fresh latex from sticking to itself. The latex mold will need to be supported before casting so that the flexible rubber can retain its shape.

Latex rubber is also used to form a protective coat on different items. The latex coat can make fabrics waterproof. It can also form a protective covering on tools that will provide a sound and comfortable grip even while insulating them against electrical hazards.

The most common use of latex rubber is for making a latex mask. This can be used for special effects in movies or even a fun element for Halloween and other occasions. It is usually cast in a face mold made of plaster bandages and then the desired characteristics are built on it step by step.

Other tips to keep in mind when working with latex rubber is that it contains a good amount of alcohol. Proper ventilation is required and do not inhale it too deeply or frequently. Similarly, the rubber will become unusable if frozen. Store it carefully in the winter months of the year.

Using Liquid Latex Casting Rubber

Posted by EnvironMolds , Labels: , , , , Tuesday, September 15, 2020 10:58 AM

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.

Making Latex Molds and Casts

Posted by EnvironMolds , Labels: , , , , , Thursday, April 23, 2020 4:30 PM

Latex rubber is a popular choice for making both molds and casts. Latex has several useful properties and it is also relatively easy to make both latex molds and casts by following the right procedures.

Liquid latex rubber is a versatiles material that is considered tough, durable and economical as well. It lends itself well for various applications in the fields of mold making and casting.

Latex molds capture details well and are usually used to make plaster and resin casts. They are also handy for casting abrasive materials like concrete as the mold will not tear despite the coarseness. The latex can also be applied on architectural details on the walls or even ceilings without the latex running off. This works especially well for making molds for restoration works.

Latex casting is usually used for making hollow molded rubber articles, toys, balls, imitation pottery, display items and flexible props. Liquid latex is popularly used for mask making as well as special effects works like wrinkles, scars and gashes for theatre, television and films. It is even commonly used as an adhesive for bald caps.

Apart from this, latex is useful for slushing casting clays for ceramic works and for coating polystyrene and other fabrics and even tools. This forms a protective and water proof coating on the items. It even allows for better handling and insulation for the tools.

How to do?

It is easy to use latex rubber for making molds and casts. The most common method is dipping for mold making and pouring for casting - No elaborate process or expensive molds are required.

Latex molds are created by dipping the model directly into the latex rubber itself. Simply dip the model into the container to get a uniform coating and then let it dry. Repeat the procedure 10 to 12 times to build up the adequate thickness. Alternatively, the latex can also be painted on the model multiple times, while allowing each subsequent coat to dry properly.

The procedure for making latex casts is also quite similar. Here, the latex rubber is poured into the mold and allowed to sit for some time. Then the rubber is poured out again. A thin film gets deposited on the inner side of the mold and will dry to form a flexible cast. Keeping the latex inside for a longer time or repeating the procedure will increase the thickness of the latex cast.

Usually plaster molds are preferred for making latex castings. This is because the porous plaster will absorb the water in the latex and allow it to cure to form a cast. Therefore, latex and other molds are generally not preferred for latex casts.

Demolding liquid latex molds and casts is also simple as they can be easily peeled off the model or mold. However, it is advisable to dust the latex surface with talcum powder before demolding, else the latex will stick to itself. Latex casts can be painted with special latex paints to get the desired finish.

Using The Best Latex Casting Rubber

Posted by EnvironMolds , Labels: , , , , , , Wednesday, August 28, 2019 3:17 AM

RD 407 Mask Making Latex is considered the best liquid latex casting rubber not just for making masks, but also gloves, props, coating and other uses. It is easy to use but does require some careful handling.

Liquid latex rubber is a popular mold making material because of its tough, durable, tear resistant and economical aspects. The same is also used as a makeup and special effects product to create varying effects for film and theatre.

In addition, there is latex casting rubber variants which are less viscous than the mold making latex rubbers. These are commonly used for making hollow toys, props, puppet heads and masks. In fact, RD-407 Mask Making Latex is considered the industry standard for making latex masks, props, gloves and a skin over polyurethane foams. This is a high quality latex that is favored by professional artists for masks, body parts and other thin skin latex products.

Latex casting rubber is very easy to use when compared to other casting materials. It comes in a ready-to-use liquid form and just has to be poured into the mold. It is swished properly in the mold and allowed to sit for a couple of hours before being poured out again. The latex that remains clinging to the sides of the mold will dry gradually and can be peeled out to become the actual thin skin cast.

Apart from making masks and props, the same RD 407 latex rubber can also be used to coat fabrics for waterproofing and insulating tools. Dipping the model into the latex and allowing the coat to dry before repeating the steps will build up a suitable protective coating over the same. Alternatively, the same latex can also be used to coat foam that has been carved into the desired shape.

A latex cast can be sanded, painted and finished as required. It will be elastic and flexible but still stays durable for years to come. Even the amount of hardness and flexibility of the rubber casting can be manipulated by adding an extender and filler like RubRfil.

Care during use
 
Liquid latex rubber is a simple product that can be used easily. It has a long shelf life and can be used whenever desired.

In case a stored latex rubber turns thick, it can always be thinned by adding some distilled water to get the desired consistency. The ammonia in the latex will also tend to evaporate. In case the ammonia smell is diminished, adding some aqua ammonia from a chemical store will restore it back to normal. However, latex should never be allowed to freeze as this will render it unusable. Special handling is necessary during the freezing months of winter.

In sum, casting latex rubber is a multi-use product that is commonly used to make latex mask but has other useful applications as well. In fact, it can be used to create almost any effect as a cast or directly on the skin as well.
