Mold can’t grow without water, so the way you can keep mold out of your paper mache is to: Use the fewest layers of paper and paste or the thinnest layer of paper mache clay that you can get away with. I use no more than three or four layers of paper and paste, and sometimes use less.

What happens if paper mache gets wet? The inside of the sculpture is foam, not crumpled paper or any other organic material. That means that even if there’s a pinhole in the outside ‘skin,’ water leaking inside won’t cause any damage. The ‘paper mache’ uses mortar mix with the paper strips, instead of paste.
Why is my paper mache cracking?
The splitting is due to the balloon expanding while the papier mâché is drying. If you place it outside in the sun to dry, for example, an increase of even just a few degrees can be enough to expand the balloon enough to split the papier mâché. The solution is simply to add another layer of papier mâché over the split.
What can I use as a base for paper mache?
How to Paper Mache. Find a base — you can use masking tape and cardboard to create almost any shape. You can also use chicken wire, or anything already the shape you want such as a basket, bowl, or box. Balloons are popular if you want a hollow item.

Plastic shopping bags — You can also wrap your base shape with plastic bags and tape, and then add paper maché. The bags will stick inside the paper maché but they won’t stick to the base. I find that paper maché on plastic wrap also takes a lot longer to dry than these other materials.

One of the most common, and easiest, ways to create paper mache is to use glue and water as the paste. A few different types of glue will work, but most people use wood glue or white Glue-All. Using glue is very similar to using flour, but it creates a stronger structure that is less likely to rot.
Does paper mache dry hard?
Use thin layers of paper mache. The mixture dries very hard, so there’s no need to add more than 1/8″ layer. I often use a paper-thin layer of the paper mache clay, and that’s strong enough for almost any project. The armature makes the sculpture strong, and the paper mache gives us a nice surface for our paint.
