Constructing a Waterfall

Howard starts with a sheet of gator board found in most art stores. To cut the gator board, Howard uses a number 11 blade and simply scores the top and snaps the board to get the perfect easy cut. He glues one of the verticals to the horizontal levels with hot glue. The first plane ends up like a box that stacks on top of another to create the different levels of the waterfall. He then adds sides to the waterfall out of cardboard to attach the surrounding scenery to. The next step is to paint the entire area a flat dark color.

For the riverbed, Howard uses river gravel from Scenic Express and full strength Elmer’s glue. With a brush he lays down a good amount on what will be the riverbed and pours the stones in using two different sizes for variation. To affix the stones permanently, he sprays a mix of water and Palm Olive dish soap.

He then pours over a mixture of 50% water and 50% Elmer’s white glue as well to really lock the stones in place. Using 100% silicone rubber sealant in clear, he begins on the water of the waterfall. This sealant is used as a dam for the EnviroTex that will be added in later. The waterfall begins to be added in with lines of squeezed sealant. Watch the full video to see how Howard finishes the waterfall with a section of a fine tooth comb.
