How to Make a Silicone Mask Part 3

< Go Back to Page 2

silicone masksOnce I got my mold cleaned out (by removing the sculpture and any remnant clay), I mixed up some Smooth-On Dragon Skin platinum cure silicone rubber (I had the medium cure time) and poured it into the nose and chin areas first, to make sure they got the most silicone.

I added a little bit of pigment for each mask I made.  In the photo above, the middle mask was my first (video), and I didn’t mix it correctly, so it didn’t cure correctly (it is still tacky, several weeks later).  Make sure to follow the directions to the ‘T’ when you work with platinum cure silicones!

My second mask (video), on the right in the photo above, didn’t have enough silicone, but it cured and turned out strong.

The last one–the fleshy colored one–turned out nicely, and you can  see how it works in the following video:

Halloween Post: Airbrush Tattoo for Pregnant Woman

Although I didn’t do it for Halloween, when my good friend, Amy, asked me this 4th of July ( a day when I airbrush tattoos on any guest to our annual barbecue) if I would paint a representation of her baby trying to escape the womb, here is what I came up with:

Here is a mask I’m working on possibly for Halloween this year (2013)

How to Make a Silicone Orc Mask Part 2: Urethane and Plaster Mold

< Go Back to Part 1

Orc Goblin Silicone Mask Sculpture (8)

I made a brush-on silicone mold of the orc sculpture I created the other day.

two part urethane and plaster mold for silicone mask of an orc (1)First, I bought some two-part urethane 70-20 mold making rubber and mixed it 1:1.  Gotta make sure you use a decent mixing container –preferably with see-thru measurement gauge on the side.

I made my first couple layers runny, so as to pick up all of the details in the clay–especially the rotten and mottled skin texture.  Only mix about 8-10 oz. (4oz part A to 4oz. part B) to do each layer.  Once it gets a bit tacky, it’s good to start mixing the next layer–this stuff kind of needs to be layered up before it cures fully, or you risk de-lamination.

After about two solid layers of runny, I added some fumed silica to it to thicken it up.

Here is the first video of the mold-making in progress:

NOTE!  Wear a mask and mix this stuff outside if possible–it creates little clouds of dangerous silica particles that are very toxic to your lungs (I found this out the hard way).

After making about three layers of the thickened urethane, especially in areas like the eyes, nose chin, ears, and around the neck, I let the urethane dry and cure overnight.

Then, I added an ultracal 30 plaster mother mold in two parts, using fiberglass mat for a strengthening material.  This is a task you shouldn’t undertake without watching several videos.  I’d recommend Mitch from Brick in the Yard on Youtube.  He’s a genius.

So, once I pried apart the mother mold, then slit the back of the urethane mold from the clay sculpture, I de-molded it and got two separate parts.

So far, so good!  I’m VERY excited to add silicone into this mold and add the mannequin armature back into it to make it fit a human head a bit more snug.

This is all an experiment, so you might want to see the next part before you follow any of my advice.
