2x6 PT board questions
I have couple of questions about installing 2x6 pressure treated wood that I hope someone could help answer.
1. Do you need to leave gaps between 2x6 PT boards when installing them? If so, how much of a gap?
2. I removed the existing boards on my deck, which were 5/4 thick PT boards. The space between the top of the ledger board/joist and the bottom of the siding is 1 1/4 inches. Should I a sand the area on the 2x6 board to a point where I can slide the board underneath the siding. Or should I force the 2x6 board underneath the siding, which will cause it to buckle out.
