I'm building a raised patio deck using pressure treated 2x6x16 ACQ treated wood. I need to have a gap between adjoining wood planks. I don't want any more gap than is necessary for the rain to run off. The wood I'm using is quite wet. Salesman at home center wasn't sure of the amount of shrinkage.
Should I just butt them next to each other and count on shrinkage to give me a gap for rain runoff or should I use a nail for gapping them? I live in the Missouri Ozarks where we get plenty of rain.
Thanks for any advice.
