Front porch repair
I am trying to find out the best material and method for installation of a front porch on my 1895 house. It currently has a new porch less than 6 months old. The frame work was treated lumber and the porch boards were pine. The boards are tounge and groove, primed on both the top and bottom, ends and the grooves before installing. It was painted with a Sherwin Williams polyurethane porch paint. The problem is the boards are coming up as the wood is defintely swelling and in some cases the groove has completely opened up and the board has completely popped out. I live in Texas and I am frustrated because I get all kinds of answers. My carpenter guy said I should have used treated tongue and groove porch boards. But I also visited a house he had done about 6 months ago and the same thing is happening to their porch but not as bad as mine. What is your answer...help.
