Pouring statues, latex molds
Hullo everyone at Hypertufa,
I wonder if anyone can help me. I've got a latex mold of a Moai head/bust, only poured one cast so far, but made the mix too dry, and got unwanted voids in it.
I read the post on cement/polymer/water slurry to coat the inside of the mold first, then fill with dry pack. My piece is about 2'4" high, and 12" square. It's real heavy, and I thought to paint slurry inside mold first, then fill and tamp, then scoop/cut/cup out the middle, to reduce the weight a bit.Finding it hard to get any definitive info on this, especially the dry pack mix design, and how dry is 'dry pack'?
Any info at all would be much appriciated.
Love this forum, very creative,
