paper mache thickness question

5414 Views 5 Replies 4 Participants Last post by  Demon Dog
How thick can you build up paper mache (using paper towels and ~40% water & ~60% wood glue) in one sitting? I was working on my pumpkin head last night adding ribbing to the (thoroughly dry) plaster cloth base and made ribs about 2.5 inches wide and probably 3/16 to 1/4 inch thick. Too much at one time, or just be patient and let it completely dry?

What is the recommended thickness for one sitting with strip paper mache and paper mache clay?

Thanks Baron. My paper mache pumpkin ribs seems to be drying okay, albeit slowly (pretty firm after 48 hours). I'll take your advice going forward and add thickness more gradually - probably do no more than 1/8 inch at a time. As you'd mentioned, I did notice a slight shrinkage in the thickness and will need to add a little more to the ribs I had done, after they are thoroughly dry.

Excellent! Thanks Otaku and Ugly Joe. I like how the paper mache gives the pumpkin a realistic shape and texture, but the two day drying time seemed a bit much. I'll try your suggestions as well as reduce the thickness I add at one time.
