I don't know about adding sand but,
I bet that the Dryloc texture can be created with plaster of paris or baking soda or both together. The baking soda would add more texture and the PoP would speed up hardening time. I haven't actually tried this, but it seems like it would work. Test at your own risk...I haven't attempted this!
