Sorry about the delay Robin I've been away for a week.. You are correct you do pour it. The first time I used it on the old layout i poured it a bit too deep and although it looked and felt as if it had set it hadn't, so when I put some boats on it (it was a harbour scene) after a week they more a less glued themselves to it. I did manage to get them off but with some difficulty. Although not so important for the stream I took great care in only putting a minimum on, and then gave it a week and then added a bit more. I did this three or four times. This time it dried quickly and non sticky. Some of it ran over the rocks so they had to be re painted to get rid of the shine.
