OK how much does Hardiboard really expand?
I am doing my siding on my new house myself. I am quite capable of doing it. I was told that
I would need 2 cases of caulking cause you have to leave a 1/8 space at each joint and fill it with caulking. Then I was told to nail it solid to a stud every 16". If it were going to move shouldn't you have nail it like vinyl. I took a drive and even walked around other houses and seen that the nicer jobs seem to be tighter joints. Not saying there isn't any caulking but you don't need 2 cases per job.
