Well, the waterproofing experiment didn’t work. I may have done something wrong, or perhaps the sealer and the paper mache clay aren’t compatible for some reason. I’ll drag him inside with my hand truck and let him dry out (that didn’t occur to me when I was making the video), and when it’s completely dry I’ll try brushing on more sealer. To do a really good experiment, I could do half of the hat brim with the sealer I already have, and half of it with a sealer from Lowes, and see if one of them works. At this point, though, I’m not feeling very positive about it.
I really had high hopes for this experiment. Sigh…
The brim on the hat is flexible now, after the rain, although it isn’t at all like the paper mache clay was before it dries. You can’t sculpt with it, I mean, or put a thumb print into it. But still.
At this point, I recommend that you read up on the two experiments shown on this site that did actually work: Julie’s mountain lion, made with Quickwall cement over paper mache clay, and Jackie’s Goddess, made with thin set tile mortar over paper mache clay.
While the scarecrow dries out I’ll get started on my hiena mask, and do more reading about building outdoor sculptures with concrete. I’m concentrating on books that show how to make relatively light-weight sculptures using ferro-cement processes (concrete over a wire frame). Some of the things I’m reading suggest that certain additives can be put into the cement to make it feel more like working with clay, and that really appeals to me. If I get excited about it and start making lots of small sculptures, I might put up another website, since this really is a paper mache blog, not a concrete blog. But, in the meantime, I’m going to stick to making paper mache sculptures for indoor display. At least we know that works. 🙂
