Ballast is placed along the railroad track to model actual ballast that holds track in place.
Talus is used to model rock debris under rock outcroppings, rocky hillsides or embankments.
We recommend adhering Dead Fall and Talus with Scenic Glue (S190) prior to pouring Realistic Water.
Also, it is very important to let everything in the water area dry thoroughly before pouring Realistic Water. Any residual moisture will be absorbed by the Realistic Water, which could cause the Water to become cloudy.
