Has anyone whitewashed the interior of their coop(s) by hydrated lime in the water only (with no salt added) and did it last for at least a year? I am concerned about the salt content of the standard recipes would deteriorate hardware cloth, nails, and screws whenever the air is moist, as well as becoming part of the bedding and food for the chickens. Note: i don't want to add any glue to the whitewash mix either.
