This is our third post in a series about how we built a replica marsh for the Eddy Discovery Center at the Waterloo Recreation Area.
Once the above ground formation was finished, we had to surface the water. While some marshes may have a still water surface, they aren’t usually glass-like. We used an epoxy product that mimics the texture of water when it sets. Openings in the acrylic surface for the lily pad stems were caulked shut to keep it from dripping down into the underwater area, and artificial duck w**d was applied before the epoxy set. It sets with a hard, non-tacky surface, so should this exhibit ever need to be opened and cleaned, the surface can just be wiped off.
After everything had a few days to rest and cure, the exhibit was fully inspected, touchups to paint and plant placement were made, and surfaces were thoroughly cleaned. The acrylic covers were installed and the exhibit was secured for delivery.
