Hi Aaron,
Thanks, I still have yet to try that AAC block. Molds are pretty easy for the smaller ones. The big ones are another story entirely. I've seen some of the stuff that comes out of Mexico, and it's pretty amazing. I have no idea how they're doing some of it. I don't- or at least haven't yet made molds of my larger sculptures(3ft+). Those are all handbuilt. Most ceramic and art supply stores carry some kind of mold making material. after trying a few I stuck with plain old liquid latex. On the bigger ones you need to build an armiture or frame that closely resembles what the final product will look like and then sculpt the concrete over that. It's kind of like doing stucco. I don't know what others use for a frame, but I use a wire mesh construction cloth. It takes hours to cut and bend and attatch all the various pieces together. It also makes for a long day when doing the actual concrete application. You can't leave it unfinished for the night and start in the next day. It's a one shot deal. I've spent more than 12 hours on one finishing up the concrete and getting all the details done and smoothed out. It's become a sort of ritual for me, and like with all things, the more you do it the faster- and hopefully better, you get at it.
