Re: Painting deeps & supers
Painting the outside of the hives is fine and recommended. I would also paint the edges of the plywood. Painting the inside of the hive is generally frowned upon.
If you are going to use plywood, before painting I would mix up a batch of diluted Titebond glue to the consistency of paint, and brush it onto the edges of the cut plywood to seal the edge, instead of paint there.
