Brad, that's the problem with all of the concealed fastening systems that slip into the board's sides. When the wood moves they can slap out again.

Probably the easiest fix is to pry the boards over, use shims to hold them in place, then face screw them down again and plug the holes. After the new plugs weather out you'll hardly see them.

Another example of why all of us deck builders preach not to use those hidden fastner systems.

Do like Joe says, screw & plug.

OK Guys, I get the point. What I was hoping for was some helpful insight on what if anything I could consider doing to force these warped boards back into submission.

Ideas? Perhaps a bow-wrench to re-align the boards and then face screw the boards down?

Unless someone has a trick to use a bowrench this way I don't think it would work, you need open joists to hook it on and space to rest it on the side of the deck boards.

Joe had a good idea, drive some tapered shims between the boards until they are close to the right place, screw the decking down. This might take several shims,everything is going to want to move as you drive them in,just go slow, watch how the movement goes. You could screw down the few deck boards that are holding to give you something to shim against.

Has anyone mentioned its a bad idea to use the clips??? John

A chisel works like the shims, but you have to be careful to not damage the wood. Ipe is pretty hard, so that is not usually a problem.

"use shims to hold them in place, then face screw them down again and plug the holes"
Why not use duct tape too?

Clips are the way to go. You just gotta use the right ones. Ones that actually screw into the wood, at an angle is even better.

Using shims and face screws is doing the same thing as a clip just not as well (face screws back out, even with plugs), just slower, uglier and won't last as long.

tonim,

thanks for your 2 year old reply, but...
clips are not the way to go, unless you are a clip salesman.

Tonim,

You say "face screws back out"

Please explain how you have observed this. I am intrigued...

I also am intersted in that statement tominster. J.
