Hi Dan,
I have an old barn that someone began to close in with cement based stucco. I would like to retrofit the barn and finish with plaster. Is plaster up for this type of abuse, or is it mearly a "sisy" type of finish for gentle use situations

?
I live in temperate Northern California (20" of driving rain, freezing temps in the 20's, and 110 degree summers) and the barn will be used for animals and hay storage. What do i need to consider? I will also be constructing some additional walls and was planning on sheeting with osb or plywood just as a quick way to give some rigidy and shear strength to my modifications.
Things I am curious about:
Is this even an acceptable use for Plaster?
Will it hold up to some abuse as an animal enclosure or hay storage?
My overhangs are currently rather small. Do I need to retrofit with large overhangs to protect the plaster from wind and rain.
What do I need to do/prep to coat over cement based stucco or OSB sheeting?
Since I am not terribly worried about a perfectly beautiful interior grade finish, are there any corners I can cut to make the whole process lower effort?
Thanks!
