The water should be warm. If it gets cold, change the water. The plaster becomes smoother and adheres better to warm water. The edges will be thin. The solution to this problem is to push the ends further than necessary and then trim off the excess before it dries. We did that and it worked well. You can also reinforce the edges with additional strips after drying. I had no problem with ours not drying out or losing their shape. It started drying before we even finished adding layers. It's supposed to have four overlapping layers, which is what we did so the structure is thick and strong. However, we let it dry on a ball so that it doesn't lose its shape as it hardens. I just took one of our kids balls that was the right size, cut a piece of tarp and propped it up. No problem with it falling apart, staying wet, warping, not wanting to stick to me or anything - even with the very thick layer of lube I used. That doesn't mean others didn't have a defective set, but we were fine. But it didn't take more than two hours. From start to finish it was within half an hour. I started the Netflix show when we opened the kit and stopped it when I took the cast off and got in the shower, so I'm sure. Haha.
