How to make your own mold silicone putty


Mold puttys are often really expensive and sometimes hard to get, so I want to show you a cheap and great alternative. Here I show you, how you can make your own kneadable silicone putty for molding.


All you need is:
silicone caulk in your favorite color (you can get it from your local hardware store),
 cornstarch or baby powder,
latex gloves,
a small bowl and something to stir,
things you want to make a mold of (for example: cabochons, metal pieces and more),
if you want to color your putty, you'll also need acrylic paint.


Step 1: Cover the bottom of your bowl with a thin layer of cornstarch. Take your silicone and add a big blob onto the cornstarch. Take something to stir and mix the components together.
It's not bad if your mass become crumbly at first, after some minutes of kneading the ingredients will be mixed - add more silicone if necessary. If your mass become sticky again, add some more cornstarch. 
At the end your putty should have a smooth, non sticky touch and a matt finish.

Note: Don't add too much of cornstarch, otherwise your putty doesn't hold together and become too crumbly. Add just a bit of cornstarch, knead it under your silicone mixture and add a bit more, if your putty is still sticky. Make it in several steps.


 Step 2: If your putty have the right consistency, it's time to color it. For this we use acrylic paint, but you can also use glitter or other paints too. Wear the gloves for this step, because it's really messy. ;)


 Now it should look like this.


 Step 3: After coloring, it's time too make the molds. Take some of your putty and shape it into the right form. Now take the parts that you want to molding and press them gently into the mass.

Let the molds dry for about 3-4h. After this time, you can take the pieces out of the putty, then let the molds dry again for about 2h. So you can be sure that the molds are completely dried. Then you can use them for different clays and resin. :)

Note: The drying time depends on the size and thickness.
After drying the molds are flexible, so it's easy to remove clay or resin.
The impressions are very clear and air bubbles should not occur, because the mass is more dough-like.
However, elaborate impressions should be hard to make, because the mass is a bit too hard.

Here you can see three resin pieces, which I've made with the molds. Really detailed, right? ;)


My personal opinion is: This putty is a much better as the putty which I bought! It's cheaper, the impressions look better and more clear. My bought putty often got air bubbles, so the molds were unusable. Also it's easy to make and I have the materials usually at home, and if I don't got them, they are easy to get. You should give this a try, so you can look, which putty you will like more. :)
The only thing which is really bad, is, that the molds aren't durable for a long time. After a few weeks they will be brittle.

  1. Hi!
    Ich kenne das als 'oogoo' und hab selber schon viel mit diesem 'Teig' gemacht. Ihn als Abformmasse zu nutzen, darauf bin ich allerdings noch nicht gekommen :) Wird aber auf jeden Fall ausprobiert, denn wie du schon sagst, es ist günstig und leicht zu machen. Und wenn man was daneben geht ist es nicht so tragisch wie bei der teuren Abformmasse aus dem Internet.
    Hattest du keine Probleme beim Einfärben der Masse, insbesondere mit dunklen Farben? Denn bekanntlich nimmt Silikon Farbe nicht so gut an und bei mir wurde zB ein Braun, das einen schönen braunen Teig ergeben sollte, nur marmoriert. Mit hellen Farben wie Rosa geht es einigermaßen, ich denke, weil da der Unterschied zu dem eigentlich Weiß der Masse nicht so deutlich ist. Dunkle Farben werden beim Einfärben aber fleckig bei mir.

    So, freue mich schon auf neue Posts (insbesondere Fimo-Berichte :)) )

    LG

    1. Huhu,

      "oogoo" sagt mir leider gar nichts, ich kenne diesen Teig nur als Abformmasse, aber ich bin mir sicher, dass sich damit gut modellieren lässt, wenn man die richtige Konsistenz erreicht hat. :)

      Ja, das ist mir leider auch passiert. Ich wollte eine braune Masse erstellen, doch bei mir sah es hinterher auch sehr marmoriert aus. Ich hatte aber das Gefühl, dass es eher daran lag, dass ich zu viel Stärke untergemischt habe, denn wenn ich mehr Silikon habe, lässt es sich problemlos einfärben.

      Liebe Grüße, Carrie :D
