Do you have a paper mache project that needs to be done by a certain time?
Or are you concerned about drying your paper mache quickly so your sculpture won’t be destroyed by mold? Either way, drying paper mache quickly is one of the most important keys to creating a successful sculpture.
an instant art medium. Both paper strips and
paste and paper mache clay
will take time to dry. Fortunately, if we keep air moving around our projects we can speed things up.
1. Use thin layers of paper mache.
If you use a firm armature, (made with either crumpled paper and masking tape or crumpled foil and hot glue), your sculpture only needs a few layers of paper strips and paste. Those few layers should be ready to paint in just a few days.
If you’re using my paper mache clay recipe
instead of traditional paper strips and paste, you can apply it in a very thin layer that will dry in a day or two. 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.
Almost all of the projects on our paper mache blog
use a firm armature made over a pattern
. The armature makes the sculpture strong, and the paper mache gives us a nice surface for our paint.
2. Put your wet sculpture in front of a fan.
To keep the air moving. put your sculpture in front of a small fan. Then turn the sculpture once in a while so it dries evenly all the way around. Remember to turn it so the bottom can dry, too.
3. Special problems for really big paper mache sculptures.
Is your sculpture really huge? For a parade float, perhaps? Then you have the additional problem of gravity moving water down towards the bottom of your sculpture.
You still want to use as little paper mache as you can possibly get away with, and you still want to put the sculpture in front of a fan.
If you’re making it in your garage, open all the doors and windows so you don’t trap a cloud of wet air inside.
Give it at least a week to dry, because the bottom of the sculpture will stay wet much longer than the top.
4. Check for dampness before painting.
Before you paint your sculpture, check it near the bottom with your thumb. If you feel any ‘give’ to the paper mache layers, that indicates that water is still trapped inside, even if the top layer of paper mache feels dry.
If it’s at all soft, let it dry for a few more days.
5. Seal your artwork.
Always remember to seal your paper mache after you finish painting it. You don’t want your sculpture to absorb water from the air around it.
If you live in a very humid area where getting anything
dry fast enough is almost impossible, don’t use the traditional flour and water paste. Use Elmer’s Art Paste
instead, because it doesn’t attract mold. It isn’t expensive – a small 2 oz. package can be mixed with a gallon of water, and that’s a lot
of paper mache paste!

dries paper mache in a DIY drying box, and made a special video to show us how. You can see it here
. And if you scroll down to the comments, Christine gave us an even easier idea. ]
