Question by bethf92272: far apart do you space the planking on a deck?
Putting our deck and a neighbor stopped by and told us to butt the planks up togeter. A carpenter said to space them. We live in Michigan if weather is something you need to know. HELP!!! Thank you!

Answer by fluffernut
We put ours a nail width apart…… spacer and worked out fine. Butting together……that doesn’t leave room for swelling due to moisture and last I heard, it rains in Michigan……and sometimes snows.

    the screws or nails you are using for the decking use one of them just stick it in between the boards the head will stop it from going thru

    I use to be in my family construction trade and I loved building decks. I simply used spikes (the bigger nails) to space them. For the railing I used to love 2X2s and spaced them with 2X4s.

    Whatever looks good is fine. There are no regulation for such small spacings. Only for joists and rafters and such.

    It depends on the moisture content of the decking. For pressure treated, I lay them tight. They come in at about 26-28% moisture content. They will dry and shrink, leaving a gap of 1/8″ to 1/4″. They will not swell back up when they get rained on to the point of closing the gap. For cedar, which is generally much drier, I space them with a 16d nail. This gives 1/8″ for the gap, which looks the best to me. Hope this helps.

    On a warm wet day they expand the most(longer). On a winter frigid night they shrink the most(so, as short as they can be), We are not talking alot, but some so normally the thickness of a nail (like the ones you are using to nail down the board ( or maybe a 4 ” nail for space on both ends. A little gap is much better than warping.

    Well it’s up to the own how wide the gap should be as long as it’s not wide enough to get a stiletto and alike caught. The recommended gap is between 3/16″ to 1/4″ to allow any debris to fall through easily. Myself I use a circular saw guide as the gap, like this one because they’re about 3/16″ and they can’t fall through as easy as nails and alike. As for shrinkage, I can’t see it being a problem as most 4″ and less boards will shrink 1/16″ if at all and that means it’s really 1/32″ either side and isn’t worth talking about.
