Is there any way of casting something with a stone or marble appearance suitable for outside use?
Hi: It sounds like you might want a product called winterstone or Vatican stone. You can get these materials from the Compleat Sculptor website, and they will have all the information you need to know about weathering and freezing issues. They also have additive items, like marble grit, and other stone components to simulate actual marble and granite in a composite material. Hope this helps, and you might also be interested in the wonderful wetcanvas artists’ online community. There is a sculpture channel, and over 114,000 worldwide members. Basic membership is completely free, and you can browse as a guest too. There are many sculpture articles on the sculpture channel that you might helpful in creating your project. Hope this helps, and good luck!
