Papa Carney is a very ambitious grandfather, he recently completed a backyard model train and garden project with his family and had a blast building a larger than life concrete mountain. He used a mortar sprayer to apply his concrete and even got some help from the youngest family member. 

Sprayed Concrete Mountain For Model Train

This DIY mountain was constructed using a combination of wood, chickenwire and fabric as the base followed by multiple layers of concrete applied with the 4 Jet Wall Blaster. They loved the texture of the concrete using the sprayer so they left it au natural and then stained the mountain with a variety of liquid stains using standard garden spray bottles.
