Earthen plaster works best without the wire/ lathe I'd use it for the base coat(s) and then use a lime top coat to seal the earthen plaster from moisture and for easier cleaning.
To get a good bond to poly bags, first fill in the depressions with the earthen plaster mix and let that dry.
Then come back for the first coat, use two coats of the earthen plaster and let dry between layers before putting on the lime top coat.
