I'm working on a project for a robotics research team that involves taking casts from patterns in a bed of sand. We've been experimenting with methods for preserving and stabilizing the surface layer of the sand so that it doesn't adhere to the cast, but we haven't found one that does the job without disrupting the sand. Does anyone have experience with a (preferably water-based) surface treatment and/or method for consolidating a sandy surface?"
What is the casting material that will be used? Metal or some type of two-part polymer resin? If the latter, then I would suggest going with the methods and materials used in industrial sand casting. That utilizes mold-making sand consolidated with clays and other additives. https://en.wikipedia.org/wiki/Sand_casting If you'll be using resin for the cast, you can experiment with consolidating the sand with acrylic dispersions, such as the Acrysol series, WS-24 or ASE-60. -- *Paul S.
