First paint in the deepest cracks with black paint with a small brush. Watering down the paint a little helps it flow into cracks. This is just to get the parts that will be hard to reach with a larger brush. We only used one 2oz bottle.

Next paint the base coat. We used one quart of light brown latex house paint. Paint everything, paint the sand, cliffs, sides of the board.

Dry brush the board with an off white. Maybe sure your bush has very little paint on it. Go slowly, make sure to dry brush the cliffs as well. You will need about 6 oz of paint for this step.

Next wash the cliffs with a dark brown paint. Make the wash thin enough that you can still see the white dry brush underneath it.

Wash the undersides or rocks and other areas that should be darker again.

Finally, lightly dry brush the most prominent rock edges with off white.
