Moldmaking Tutorial: Seamless Skull Mold With 5110 Silicone

In this tutorial we make a 1 piece, seamless skull mold using 5110 Platinum Silicone thickened with Thixo thickener. We made the mother-mold with our 6" plaster bandages. This is an easy, inexpensive way to make bust molds that can be used for casting rigid casting foam, resin, and other polyurethanes.

Thank you!

This was a great video

[@brickintheyard]

Thanks!

Para não rasgar o melhor seria usar borracha látex, ou o silicone é melhor?

[@brickintheyard]

Latex is great for concrete casting but not for resin and foam. 5110 is ideal for casting polyurethane resins and expanding foams.

@@brickintheyard Muito obrigado pela dica, gratidão.

[@CherylBrune-tg1lo]

What is the original skull u started with made of?

[@brickintheyard]

ArtKast Polyurethane resin.

How can I pour concrete skulls in this manner?

[@FuzzyBunnyofInle]

I'm so happy I'm not the only person researching this,..for totally normal person, normal reasons.

[@brickintheyard]

You could use this for concrete casting. But you might want to make a slightly thicker mold with a resin mother mold using TC-5130.

Great video! Would I be able to pour flexible prop foam in a 5110 silicone mold?

[@brickintheyard]

Yes, but the firmer silicones, like 5130 or 5140 are better suited for self-skinning flexible foam.

[@HesCrafty]

@@brickintheyard Awesome! Thank you for the reply. Can I still make a mold out of the 5130 silicone? Thanks again. And thank you for all the awesome content.

[@brickintheyard]

@@HesCrafty yes. Just be sure to account for the expansion force of the foam.

[@HesCrafty]

@@brickintheyard Thank you so much again. Very appreciated 🙏🏼

[@jacklambert4958]

Is the 5110 better to use for than your platsil 10 silicone?

[@brickintheyard]

Not so much as better as different. 5110 is a slower setting, lower viscosity formula so there is more working time and it is much easier to use for poured molds, also less expensive.

[@jacklambert4958]

I do like the idea of a longer working time. Thank you

Gorilla brand hot glue doesn’t cause inhibition.

Thanks!
