I am makeing something for my mother and I wanted to set a picture in a cement stepping stone. If I can't do it with cement, then I was thinking of plaster of paris. Now that I want to do this project, I don't know how to go about doing this. HELP!!!
Let's see... I think plaster might be too fragile. You know, you can mix equal parts of plaster and cement. It'll set quick enough, and be strong enough. Because, cement can take days to set properly. With the mix, half an hour, tops. The picture alone will probably get ruined, like putting paper in water. I'd keep it in a frame, or glue it in later. I'd leave a space in the stepping stone so when I put the picture in, it'd lie flat, not on top of the stone. Inset. Then I'd cover it with plexi-glass. A lot of hardware or craft stores will sell little sheets. In fact, maybe I'd just make the stepping stone into one large picture frame. I'd use something of equal size and make sure that I used a lot of release (wax, soap, grease) and some pieces of wood to make a mold, where you'll pour in the mix. Make sure you coat anything (table, boards of wood) in release that you don't want stuck to the mix. Then it's just a bit of thinking and testing to find what will work.
