I am a professional/master sand sculptor. We DO NOT use glue to bond the sculptures together. It is only sand and water and is simply highly compressed. We do use glue as a weather screen, mixed at a ratio of 1 part glue and 10 parts water. We only use white glue which is already 80 water, so the final percentage is about 2% per volume.
Just like the paint on your house, it does nothing to hold it up and simply protects it from the environment. In fact, glue is heavier than water....too much glue can make the sculpture fall.

Yes. Sculpting sand is usually a fine grit sand (if the local stuff is too coarse) and the binder for the fine work is typically 1/2 Elmer's white glue 1/2 water mixed into the sand judiciously.
