Is there a good way to glue teak decking to a sheathed deck?...

Is there a good way to glue teak decking to a sheathed deck? I am restoring a boat who's plywood deck is ruined because the teak decking was fasten in a really damaging way, and I was wondering if I should use teak decking, and if so how do I attach it without ruining the deck?

The bottom line is that, if you put that many screw holes through the sheathing, you are eventually going to have water ingress.

One way around it is to use battens as sleepers running athwartships and screw the teak planking into that. A few things to bear in mind are that this will raise the overall height of the decking obviously, the edges will need trim over the gap, and the sleepers will need to be close enough together that they don't sag when you walk on the deck but far enough apart that you can effectively reduce the number of deck penetrations.

You could also use teak ply and glue it down. Depending on the camber of the deck, sandbags are a great "clamp". In this case, it's usually best to make your own ply by laminating teak veneer to marine ply. The cores in most teak plywood is not robust enough for outside use, especially if your decking is only 1/4" thick.

If the current decking is toast, I assume it's getting replaced. I'd definitely suggest using epoxy and cloth to sheath it rather than a styrene-based resin. Epoxy penetrates the wood far better and is also a much better barrier coat.

It's tough to be any more specific without more info on your project. Care to post a pic or two ?

You can glue down teak planks, usually 3/8-1/2" thick with epoxy. use small blocks of wood either hot glued or temporarily super glued for alignment and weights (we use bags of lead shot) to hold them down. Use spacers made of starboard and clean excess epoxy out well before it kicks. We usually assmble panels up to 24" wide with deck caulk and then glue the panels down after fitting.
