On the layout I just tore down a few months ago (time for a rebuild) I used Ceramic tile grout. I model HO and it spreads easy,comes in a variety of natural colors, and the texture looks great. I had some left over from a tile job in the house and decided to try it. If I remember correctly, I think it runs around $20 for a gallon bucket. Can also be used to model fine piles of stone. Takes about 24 hours to dry completely
