Old wood up so the cup is on the bottom. This puts the
crown up and it will shed water. Otherwise the cup will
hold the water which is worse. I have both on my deck
as I bought milled boards with rounded edges and 3
grooves on the bottom and didn't have any choice in how
to lay them. I know better now.
Yeah - I agree. But I thought I read somewhere (Understanding Wood)
that they said you should put them the other way. Plus, some show on
HGTV had a couple of "expert" carpenters say you should put the old
wood down - so that it would shed water! I see a lot of bad or just
plain wrong woodworking/carpentry information on tv these days. DIY is
lay them so that they warp with the center up. This will do a couple of
1) shed water instead of holding it
2) make for a smoother deck. If you lay them cup side up, the edges will
stick up, and you'll have lots of little ridges. Cup side down gives you a
"hilly" surface, but its alot easier to walk on, and less trip prone.
Use a under the board fastening system and don't worry
about any of that. I used Deckmaster but there are others.
You will end up with a MUCH nicer looking deck that will
last a few years longer. Fastner failure is the biggest
cause of deck failure.
If you MUST fastnen from the top, use square drive
stainless steel screws.
