In this video tip I want to show you two ways to deal with deck boards
0:06
One way is quite common but far less than ideal. And the other hardly ever happens and it does a really good job
0:14
Here you've got the deck floor joists. They're typically 2x8 or 2x10 lumber
0:20
Here are the deck boards, usually 2x6, sometimes what's called 5 quarter by 6, which actually
0:27
measures 1 full inch in thickness, so half an inch less than regular 2x6 lumber
0:33
The problem is that there's only one joist here over the joint between two deck boards
0:39
This causes two problems. First, any fasteners are going to have to be driven close to the ends of the boards
0:44
encouraging cracking. But more of a problem than this has to do with moisture
0:50
The boards are tight, so rainwater gets in between the gap and it stays there
0:56
The wood stays damp for long periods of time and this promotes rot
1:02
Wood is really a whole bunch of tubes left over from when the tree was alive, and these
1:08
wick moisture up past the ends of the boards and really make rot happen
1:14
It's not unusual for the ends of deck boards to rot out quite quickly, and that spells
1:18
the end of any deck far earlier than should happen. Over here we've got two joists
1:25
You don't have two joists everywhere, but only where deck board ends meet
1:29
You can plan this ahead of time. This allows you to draw the deck boards back so there's about a quarter of an inch gap
1:34
between them. The joists are typically one inch apart, which allows you to drive fasteners well back from
1:42
the ends of the boards, so there's far less chance of splitting
1:46
The main advantage of all this is that it allows rainwater to simply drain on down through
1:54
and the ends of those boards to dry. When they stay dry, they're not going to rot, and you can really extend deck life with this
