Waterproofing paper mache ideas?

Hi there. I want to water proof my paper mache masks taken off clay forms for all weather wear.

I was thinking of trying Hod Podge or whatever it's called, my friend gave me some.

Any other ideas?

    I use Krylon Crystal Clear (satin or gloss) spray paint to weatherproof shiny masks. Sometimes I also paint on a layer of Sculpt-or-coat (a tough theatrical goo similar to acrylic medium) before I spray on the krylon. The sculpt-or-coast is moisture resistant, but needs the crystal-clear layer on-top to really shed water well.

    And I use Dorlands Wax medium (from most art stores) to weatherproof matte-finish masks.

    Make sure to coat the inside and edges of the masks too, you don't want rain sneaking in the edges or the back of the mask.

    If you really want any paper mask to hold up to water you really should use an oil based sealer or resins. I often use spray polyeurethane or brush on if I want a more solid coat.
    Polycrylic is good but is is meant for water clean up so it can soften and allow moisture to penetrate eventually.
    Another option is to use a slow setting epoxy resin, mix and brush on with a chip brush so you can toss it afterward

      Got to agree with my brother on this one,
      All waterbased pruducts will eventually soften with enough exposure. I started usin epoxy resin on the insides of my masks, as they were softening from my own breath and sweat when I used masks for dance or such.
      Oil based products tend to be glossy so this with affect the finish of your mask. I have been using Polycrylic to seal most of my masks but I won't wear that in full on rain.
