Introduction: Inexpensive Reusable FX Wounds With Silicone and Make-up

Hi, welcome to my instructable.

In the past year i've been experimenting with common silicone (grout sealer), perfecting the process so it can be used as an alternative for sugru. I started with this instructable about oogoo.

So a while ago my friend had a halloween birthday.
I have made molds and bellows with silicone so why not some prosthetic wounds and  scare some people really good.

In this instructable i'll show you how to make your own  wounds, fake blood and other prosthetics on the cheap.
All made  with common silicone(grout).

Step 1: What You Need

You'll need some mixing tools to mix your silicone and additives
these will get messed up with silicone after use(preferably not plastic because the naptha will dissolve it).
-Mixing cups 
-Stirring sticks (popsicle sticks, brushes, ruler, spoon)
-Something to smear your silicone on to (preferably flat and smooth so you can peel it off easily)
  you can always tape an area of a table or cardboard with smooth packaging tape.

-Silicone (transparent)
-Foundation (Make-up)

photo 3 For the siliconeBlood you'll need:
-Silicone (transparent)

-Silicone (white)
-Acrilic paint
-FX prosthetic glue
-Red and Blue make-up (blush works nice this you can mix into your silicone)
-Toilet paper
-Plaster of paris
-Petroleum jelly 
-Brushes different sizes

Step 2: Inspiration and Research

Do your research and draw inspiration from the craziest scars blood and FX wounds there are!
Your options are limitless you can build any wound you want with this method.
Just take your time give it some love and the result will be mindblowing.

now i want to make a zipper face-mask!

Step 3: Safety Precautions

Before heading on
if you are working with my mix
the ingredients used are toxic 
the naphtha is toxic
and the silicone is also toxic (mine is 100% silicone dissolved in vinegar)
Safety precautions!
Repeated or prolonged skin contact can cause irritation and dermatitis.
May cause drowsiness or dizziness. Extreme exposure such as intentional
inhalation may cause unconsciousness, asphyxiation and death.
Harmful to aquatic life.

Precautionary statements
Prevention Keep away from heat, sparks, open flames, welding and hot surfaces.
No smoking.
Keep container tightly closed.
Ground and/or bond container and receiving equipment.
Use explosion-proof electrical equipment.
Use only non-sparking tools (if tools are used in flammable atmosphere).
Take precautionary measures against static discharge.
Wear gloves, eye protection and face protection (as needed to prevent skin
and eye contact with liquid).
Wash hands or liquid-contacted skin thoroughly after handling.
Do not eat, drink or smoke when using this product.
Do not breathe vapors.
Use only outdoors or in a well-ventilated area.
Response In case of fire: Use dry chemical, CO2, water spray or fire fighting foam to
If swallowed: Immediately call a poison center, doctor, hospital emergency
room, medical clinic or 911. Do NOT induce vomiting. Rinse mouth.
If on skin (or hair): Take off immediately all contaminated clothing. Rinse
skin with water/shower.
If in eye: Rinse cautiously with water for several minutes. Remove contact lenses,
if present and easy to do. Continue rinsing.
If skin or eye irritation persists, get medical attention.
If inhaled: Remove person to fresh air and keep comfortable for breathing.
Get medical attention if you feel unwell.
Storage Store in a well ventilated place. Keep cool. Store locked up. Keep container
tightly closed . Use only approved containers.
Disposal Dispose of contents/containers to approved disposal site in accordance with
local, regional, and national regulations.


Step 4: SiliconeFlesh

Now to make some sick wounds you'll need a base.
These first layers of silicone will give you a base to work on .

First you need to know how much pigment(make-up) you need to add for your desired skin color 

Remember to mix tiny portions at a time, this will set up pretty fast as the naphtha evaporates quickly.
-mix your silicone grout with naptha just enough to thin it out and make it stirrable 
-add your make-up, try to use tiny dots at a time it will blend as long as you mix it properly

Now you need to know how thick you want your mix to be(it needs to be easy smearable and still hold its shape).
-now you can add some more naphtha to your mix.. or not

The skin color used in these photos is my first try it was white silicone with red acrylic paint.
Later on i used make-up with transparent silicone to mimic real skin.
This didn't harm my sculpt as i builded it  in layers.

In order to create a cut you need to smear out 2 globs of your mix.
With your popsicle stick/ruler and take a glob of your mix.
Hold your stick at a angle so you create an ridge.

Ridge one
Draw an ridge with your silicone make the ends go down.
Ridge two
Do the same here only mirror it so the highest edges face each other.

Now let your sculpt cure.

Don't panic if it not looks like how you wanted it.
It takes several layers of this to build a nice scar, just make sure your sculpt cured before you seal it with more silicone.

At this point thicken your ridges so it looks more thorned.
Quick tip: thin layers are better than in thick globby layers it gives you more control over your sculpt but it takes more time

For each layer you need to prepare a new batch , this is time consuming but gives you the opportunity to add different colors to your sculpt.When you use transparent silicone it's well...... transparent just like a real skin.
Add a bit of Blood Red and Bruise Blue to your layers and cover it with normal skin color to give the effect YOU want!

I made some video's about the sculpting process.

Step 5: SiliconeBlood

To make your silicone blood 
take your silicone and fake-blood

-mix your silicone grout with naptha just enough to thin it out and make it stirrable
-add your Fake-Blood
The more fake-blood you add the more runny it will be and it won't cure properly. Some blood then sit in droplets on the rest of the cured mix it is a nice effect but wont last long you can rub it off and it will bee too runny better to use pure fake blood for the finish then this.

If you are happy with your consistency try sculpting.
Sculpt either on your scars or make a new sculpt it doesn't matter.

Step 6: Depth and Layers

Continue to add more layer with each layer you'll add more depth.
Don't forget to make bruises, some blood silicone will do  and some blue makeup works also good.

When you are adding bruises / spots :
You dont have to make a mix of silicone with colored make-up for the bruises.
Just simply paint/sponge it on with a brush like you do on a real human.The the next layers of silicone that go on top of that will seal it.
Your silicone will not stick to the make-up initially so dont cover the whole sculptwith make-up. Work in layers!

Add some black spots in your cuts/wounds to give more depth this can be done before the blood process or after just do it when you want it.

As in icing on a cake,
give your sculpted wounds a topping of siliconeBlood.

After this last layer of blood has cured you have 2 options:
The silicone is very shiny
If you don't like this
- buff out some areas with your some cloth
If you do like this and thus to protect this look
-give it a light coating of just transparent silicone remember that you don't want to see any brush strokes

This last option gives a glass like finish and you can see through it, it stays shiny and gives more depth

Step 7: Get Ready to Become a Zombie

When you are done and satisfied make sure to let it cure for about 24 hours.
Now it has cured its time to peel of your prosthetic, make sure to be careful although the silicone is pretty though thin thin pieces can rip or deform easily.

At this stage your prosthetic is cured and will shrink slightly (depends on how much naphtha u used).

I have noticed that most things including my fx skin glue(spirit gum) will not stick to cured silicone.
So in order to make an prosthetic that will stick to your skin you need to upgrade it a little bit with TP... Toilet Paper Man's best friend.

Getting ready to TP your prosthetic
most luxury toilet paper is in multiple layers and nice little designs on it
if you have this you need to take apart the layers try to use only the layer without the design or else you have a chance that it will show up on the bits that sticks out and glued on the skin(its not the end of the world you can put make-up over it).
Or just buy some plain old single sheet toilet paper and you can skip this process 

Your pieces of single sheeted toilet paper should be bigger then your prosthetic.
It should and unbroken as you want no gaps and preferably no overlapping pieces of tp on the back(it just gets messy)

TP your prosthetic
-mix some clear silicone with naphtha
-smear it on the back of your prosthetic
-stick your toilet paper on top of the wet silicone
Make sure the silicone doesn't  penetrate the toilet paper, it just needs to stick to the back.
At this stage i took some naphtha and poured it onto the back on top of the toilet paper so it would combine the layers more effectively.

For safety its better to let your prosthetic cure for about a week or more to make absolutely sure that no solvents will seep into your skin after applying.

Apply your prosthetic 
Now that there is some surface for your FX(spirit gum)glue to adhere.
-clean your skin where you gonna apply of any dirt and greasy and wait until its completely dry
-apply your glue on your prosthetic and wait till its it becomes really sticky
-now with a cotton swab stick apply some glue on the edges and your skin
-press firmly and continue until the glue has dried

Finish the applied prosthetic
In order to blend your prosthetic with you skin you need to use make-up.
-apply some blue blush with a brush
-make bruise spots on the edge of your prosthetic and your skin
-add some red over the blue to make it look more real (or not)
-wipe some of it off  if it is too much or even wipe off most of the makeup it will give a dull finish with a little color
-now its time to get really messy  add some FX fake-blood and cover your wounds with it. The more the better....=D it will wear off and mess every where.
You can never use too much fake-blood!

Step 8: Molds and Other Variations

Once you are done experimenting and are familiar with the process you can start to make wounds out of molds.

This replaces a whole step of making the base at the scarring process.
You still need to add more layers and depth into it but its a nice head start.

Making a positive
To make molds you need to make a positive wound.
Note that you only need to make a BASE for the wound
You can either make one from silicone or you can create some awesome effects with clay or play-dough.

Making the mold
Make sure your mold is modeled on a tray or somewhere you can make a clay wall so that you can pour it.
-make a clay wall/divider
-grease up your positive base wound (anything that will come in contact with the plaster)with some petroleum jelly.
-mix your plaster with water
with your bag should come instructions o how to mix it and with what amounts i'm not reinventing the wheel.
-pour the plaster into your positive
try to make sure there are no air bubbles in the plaster while and after pouring(by gently tapping on it  or vacuumize it )

Working with clay gives you some advantages as over silicone. You can have more control over the outcome as clay is forgiving you can fix mistakes. Also like i did you can make scratches with your own hand in the clay.
I even made a replica of a plaster denture replica (mold made with silicone then poured with plaster of paris) which i used to make bite marks in my clay.

This video shows how to fill a mold and how to apply toilet paper to it.

Step 9: A Few Words

Although using silicone for these wounds came out quite nice, the processing of it is quite harmful if you do not take care of your safety!
Also the silicone is quite stiff and though compared to other rubber/flesh like materials you would use for FX wounds.

Meaning its durable but because of these properties the silicone prosthetic will:
-Release from your skin in areas where your skin moves too much.
-This also happens if you have a big prosthetic and the skin underneath it twists.
-Same thing happens where the areas of your prosthetic are too thick.
The silicone is way stiffer then your skin so it will not flex as much and begin to release.
I imagine if u use liquid latex, modeling wax or gelatin or anything else it would would do the same depending on the stiffness.
Conclusion: don't get your prosthetic too thick or big cut it up in parts, else it will release easily after it has been applied to the skin.
