That took a set of brass ones to do knowing that, unlike styrene, you can't just wash it off. The drywall compound I'm familiar with should come to a nice finish just by brushing over it with a medium bristle toothbrush. It will look great if (when? ) it works out.Originally posted by Matthyro
It seemed to take a long time to get all the stones in place. I then used a coat of drywall compound as mortar. Once dry, I will sand it lightly then give the stones some paint.
