I have brand new James Hardie Cement Fiber lap siding. I would like to know if it should primed before painting even though it comes pre-primed? I am concerned about the caulking that was used in between each lap, wouldn’t that need the coat of primer even if the boards may not? Also, In your opinion which is the “Best” exterior brand of paint to use on this type of siding?
