Hi,

Could anyone advise me on how best to seal the inside of a paper mache mask?

I recently made a mask using wheat paste. I had read that adding salt to the paste would help in preventing mold, so i did that. I live in a hot, humid climate. So far so good, the mask is a a couple of months old, and while it's lost its shape a little, I see no mold. I would like to seal it, though, to be on the safe side. I'll probably use paint or Mod Podge on the outside, but on the inside, i e the part that touches the face (and it's a close-fitting mask) I would like to use something that I know will not be harmful to my skin. I have considered Mod Podge as it's supposedly non-toxic, but I think that it might feel kind of sticky. Another thought was maybe to paint it with a couple of layers of plaster of paris. Or maybe use plaster gauze?

I'd appreciate your thoughts. Thanks!
