I'm using latex molds inside mother molds made of plaster or of fiberglass. Do any of you have suggestions of something to make the floppier parts of the latex mold stick to the mother mold, so that I can handle the whole thing better without any flopping or bending of the interior mold (does this make sense?). I've tried a few adhesives, of course not much sticks to latex, and I don't want to use anything that would damage the inside mold.
Great forum, and thanks in advance for any suggestions

Normally, while making the rubber mold, you would add some ribs in those weak spots, so that the rib actually has to be pushed into the mother mold to hold it still.
Once the mold is made, however, I don't know what you might do to change it unless you're ready to make a new mother mold. In that event, you could add a few ribs to your rubber mold first.

HI MELTED STONE. if your mother mould is made already.then you would put the latex mould inside your mother mould first to stop the latex from flopping about then fasten the mother mould together on top of the latex before pouring in your casting material.hope that's what you mean.

HI MELTED.STONE i would like to ad though that a latex mould should not flop about unless it is large or if its small to medium it maybe over thin so you would have more success with making thicker moulds several coats of latex.at least.
