Yes , I use a garden sprayer, and I am wanting concrete or ferrocement to cure and not dry/ where papercrete your wanting the water to dry, but if you could make papercrete dryer to start with/ you would have a stronger end result, The papercrete I made I used a drywall blade on drill in 5 gallon bucket to pulp and mix cement and kept mix faily dry.
