5/4" or 2" redwood deck boards


I have a deck with 16" OC joists. My friend is telling me that 5/4"x6 boards are too thin and will break unless I have 12" OC joists, but my research seems to indicate that 16" OC is a perfectly fine span. It's going to be a difference of $1,500 for 5/4 vs $2,300 for 2x6.

The 5/4 will be laid 90 degrees from the joists, not on any angles.

Should I just pony up the extra $800 for the 2x boards, or will the 5/4 boards be ok?

One more quick question...

If I use 5/4x6x12' boards, how far apart should I screw them to the joists?

It depends on the humidity there at the time you are laying them.In the old days we would just space them with a 16 penny nail and never had any problems.

I have always just used a standard carpenters pencil as the spacer, using the thinner edge as the space.

And CROWN UP .

Sorry, I phrased that question wrong.

We live in Utah, so it's a pretty dry climate. I'm expecting the boards to shrink, so I'm going to butt them tight and hope that when they shrink, I get a nice 1/8"-1/4" gap.

However, my question was how far apart should the actual screws be lengthwise? Like, should I screw it in one on each end of the board and every 3 joists?

You really don't want to put more than 2 because of wood movement.More is not always better.

And do not use galvanized screws!
All I ever use is ceramic coated.
Stainless is nice but about twice the price and it's a soft metal so you'll get some that strip out.
Using an impact driver is the fastest way to drive the screws. A cordless drill is about useless.

You might want to look into a hidden fastener system, It makes the deck look much better.

And rethink those odd ball dimensions.
Most often lumber comes in 8, 10, 12, 14, and 16' lengths.
