Finally started laying down the deck planking, which is 1×6 Ipe
(Ironwood). This stuff's supposed to last 25 years at the boardwalk,
with a million people marching on it and salty air, so out in the dry
sticks it should last much longer.
The first thing to go bad on a deck is the structure. So, I made sure
to flash the ledgers (which also keeps the house from rotting), and am
covering the tops of all the structural members with leftover strips of
bitchathane from the roof, stapled down with SS staples. All the lumber
ends were brushed with copper green, and did lots of caulking to try to
keep them dry.
