The texture of it. What did you use and how was it applied?
its white PVA glue with water. 80-20
But I applied it in parts, since I dident have the room to do it at once. So what happened was, I add some glue to the board, apply the sand and let it dry. The apply more glue, but this time, just, a little bit on top of the sand as well.
And that what gives it such texture.
