How to Make Paper Mache Smooth
Sculptures made with traditional paper strips and paste are sometimes bumpy because of the underlying armature. This is especially true when you make armatures with crumpled paper and masking tape, like I often do.
In the video below I give you several ideas that you can use to make your sculptures smooth.
Make sure you also watch my newer video about making paper mache clay smooth. It’s the same idea (but a better video). Basically, just skip all the products mentioned on this page and use drywall joint compound, instead.
And watch this video to see 5 tips that help you apply paper strips and paste so they’re smooth, right from the start.
Some roughness or bumpiness might be exactly what you need for your next paper mache sculpture.
In fact, the signature ‘look’ of paper strips and paste can even add some interesting character to the piece. But some sculptures need a smoother surface to paint.
You can find all the recipes I mentioned in the video in the Recipes page. There’s a link to it at the top of every page.
The bumpiness of traditional paper strips and paste is one reason why I developed the paper mache clay recipe about nine years ago, but even if you don’t use the paper mache clay recipe you can still get your sculpture as smooth as you want it.
Before you begin adding the paper strips:
The paper will lie down smoother if you tear the paper instead of cutting it. The type of paper is also important – some paper is too stiff to form itself to the shapes of your armature. Newspaper and the paper that’s used for phone books both work really well. The heavy brown paper from paper bags can also work if you use enough paste – the water in the paste will soften the paper. Most magazine paper is too stiff.
A light touch might be all you need …
To make traditional paper strips and paste smoother, often all you need to do is use very fine sandpaper to smooth the edges of the paper strips. This will also help if you use raw flour and water paste, which leaves tiny bumps of dried paste on the surface of your sculpture.
Products you can use to fill in dips and smooth the skin on your sculpture.
Some people like wood filler. I personally like it for wood, but it dries out fast if you don’t get the lid on really tight, so I don’t use it with paper mache. Also, the containers available in my local store are really small, although they do have larger containers available on amazon.com. You need to be careful when choosing a wood filler, if you decide to try it.
Some people suggest using Bondo. The Bondo company also makes wood filler, but the product I’m talking about here is the epoxy putty made for auto body repair. It dries really hard, and fast.
If I wanted to use an epoxy product I’d use Apoxy Sculpt or one of the other epoxy clays that were developed for sculptors. They give you much more time to work. But that’s still not my preferred way to make paper mache smoother.
