Plaster of Paris HELP?

[renayh]

This week I received my Monster Clay in the mail
I decided to make some test scales out of the clay, I then poured plaster of paris over the top
When it was time to lift the plaster off I found it was sticking to the mdf board I had placed the scales on and when I tried to get the plaster of it cracked into pieces. There were a few bubbles on the scales but they were barely noticeable

How do I solve this problem ?

Put Vaseline all over where you are pouring the plaster. This will act as a release agent. For the clay fluke mold you won't need to use Vaseline. LOTS of Vaseline is used! I bought three of the big jugs (cashier thought my mom and I were nuts), I only have 1 1/2 left.

Thanks so much for the help :)!! I will give it a try

Are you casting a silicone or latex tail?

If you're doing latex, just make sure you get all the Vaseline off your mold before you cast any latex.

Good luck with your tests!

Im casting a silicone tail :)
Will vaseline effect the silicone as well ?
Thanks :)

It might! Just clean your molds really well.

ive had an extremely light coat of Vaseline in my molds and the silicone cured fine, but please do small tests once you've cleaned your molds. you don't want to wast product.

Yeah i will have to do heaps of tests seeing as though silicone is so expensive in australia

[Trident True]

yeah you've got that right nearly 400.00 for a gallon of silicone.

[Mer-gal]

OMG, it is that expensive in Australia! That is insane!

yep that is for smooth on's dragon skin. the mold max 27T is between 250. 280 depending where you buy it from. the reason its so expensive here is because of the custom duty business have to pay to import it into aus, so the business has to make a profit.

Yeah it is so pricey :( i'm very nervous too use it and I really don't want to mess up

Does anyone know a mermaid that has used mold max, I might look into it
