The first thing that happens before production begins is that stone need to be thoroughly washed and scrubbed to remove any lose parts or dirt from the surface. The next thing is to let the stone dry well, or any stencil material you want to adhere to the surface is not going to stick and would probably release during blasting; patience is called for when working with stone. Only when you are sure that the stone is dry and won’t sweat anymore do you begin the process for the actual sandcarving.
