Paper mesh?
I hope you're not planning to use this for fursuit work

Paper Mache is very strong, and easy to work with. It was used by the Chinese as body armor at one point. It makes a very good and cheap mask.

I wasn't worried about the strength. Its the fact that sweat will just melt the work e____e

Yes water is its number one enemy, but sweat isn't enough for that. I built an all black furred mask with paper mache base and that refused to melt while it was being worn on a hot summer day. Sweat isn't enough. Since the fur is applied with glue, they provide an almost waterproof layer and it also adds strength to the mask. You need to apply 4 layers to make it strong enough for this job.

Sorry, typo, what I meant was paper mache, (now updated), it is actually just as strong as resin once fully dried. Think of it as paper dipped into paper mache paste then pressed onto the mold.

KanataWolf and Wafrex have you ever thought of sealing the mask before you start furing like with a clear spray sealent or somthing along those lines so it can get wet and wont damage the mask

We did thought about that too. I usually spray the inside with paint. to make it look nicer and prevent internal moisture from ruining it. Spraying it from the outside with either paint or clear coat is not a good idea, because that means the glue for the fur will be holding onto the paint not the paper Mache, which is a weaker bond. The only idea I had was to spread glue on the outher layer covering the entire surface and as you are furring. That way it will make the mask stronger, make it watertight as you are furring it.

I didnt think about that i just started a toony mask (have no clue what animal) and i was going to do the spray but now hearing what you have to say its sounds like not the best idea
