Deck Board Gapping


When deck was built two years ago I snugged up each board to the other expecting the boards to dry out and leave a nice little gap. That did not happen. Anyone have experience ripping a larger gap with boards in place.

Re: Deck Board Gapping


I think it will be easier to remove and reinstall the boards. The alternative is to attach straight edges and run the roundover down each joint finishing the ends by hand.. Why all the sudden the issue, give it until this spring...

Re: Deck Board Gapping


If that's possible, it wouldn't be easy. Ripping a gap, easy. Easing the edge (rounded over) not so easy with boards in place. If you don't care about the sharp corner left by cutting, why not just screw down a straight edge and run the saw down the joint?

Re: Deck Board Gapping


Since the boards were supposed to dry out we can assume pt wood.

If the boards were wet when installed, they had to shrink after drying, even if only a little. There wouldn't be any puddles lying on them.

I've never had a HO question NO gaps.

You would think but then why is he in this pickle? No gaps is usually the goal great point!

I would think that if it was PT it would have shrunk some. I will always gap an 1/8" minimum no matter what. Some of that PT decking can come in pretty soggy

That seems like a pretty big gap to start: probably a 1/4", then add shrinkage. Seems big, like swallow a high heel big.

Last summer it seemed our pt boards were all straight out the river. We installed them butting and they all dried out nice. Had one where we had to replace a couple boards before staining but most of it was perfect. Maybe the op will return..

Re: Deck Board Gapping


With P/T wood, I never gap, I always install tight. Then they shrink and a small gap is left.

With composite, I use a regular, common 16d nail on ever joist. Nail the new deck board, place nails on the other side, repeat till done. I was going to buy deck spacers, but for the cost of one space I bought a whole box of nails.

Re: Deck Board Gapping


That's just what everyone seems to do, I ran into a few guys that slam em tight. Maybe it's cause there is so much moisture here, they don't realy shrink.

Re: Deck Board Gapping


The composite we installed this year had the spacing built into the clips. What a PITA but it looked nice

Re: Deck Board Gapping


a ts-55 track saw would work nice in this instance.
i wouldnt imagine you would need too much space cut in, a blade width should be fine.
i also would like to know why this is a problem

Re: Deck Board Gapping


Never thought about putting two blades on a skilsaw. I'm sure that'll come in handy sometime!
