I'm new. And I am not a woodman, just someone who procures the services of one. I hope someone here can help me with a question. I am having a house built and I have hired a carpenter that I believe to be very competent, but he made a statement today that I question. I wanted a 1x6 T&G Ceiling on my front porch. When I showed up at the end of the day today to see it, it was riddled with exposed finish nail heads everywhere. I asked "why didn't you blind nail them". My guy said it wasn't a good idea to do that on a wide board like a 1x6 on an exterior application because of too much humidity/movement and that you had to get more nails in the face of the board. He said you can do that (blind nail) inside, but not outside. I was planning to spray a coat of poly on this ceiling and I can't imagine seeing the nail heads in a clear finished ceiling. Any thoughts or comments on this?
