I bought this along with silicone molds to make some succulent flower pots as gifts. If that's your plan DO NOT DO THAT! In fact, if you plan on using this on anything that contains water, don't! I got the impression that the concrete stays solid after it hardens. However, if it gets wet (e.g. from watering a potted plant), the concrete will become wet and cloudy again. It still holds its shape, but at the bottom I could easily nick it with a toothpick, and the wet, muddy clay peels off anything it touches, like the shelf it's on, so it's not ideal for at all gifts or crafts. But I also don't understand how you can keep a post in the ground or fill it with something industrial that can get wet again.
