I did a papier mache sculpture and I want to smoothen it. The end result of my paper mache has creases in it. I want an end result to be finished like it was done in wood, plastic or any solid smooth surfaces but can with stand with minor stretches or stress.
I tried coating it with plaster of paris and then sanding it to smoothen the surface, my only issue with this approach was, plaster of paris was too brittle and falloff easily from the mache. I don't also want to over-coat the paper mache with plaster of paris as it will be too heavy. I think i only coated it about .5 cm of thickness. Patching compound is another that I have in mind, but i guess the result would be similar to plaster of paris. It would be brittle and chip off easily from the paper.
What are some ideas or solutions you can advice me to do? I need it to be flexible that it blends well with the property of the paper machet. the papier mache is only as thick as .5 cm or less, probably 6-8 layers of paper. It also need to be cheap and readily available.
