I would be more concerned about movement in the old deck putting strain on
the veneered deck seams. I believe it would probably work but I would
suggest a layer of 6oz glass and epoxy over the old sanded and acetone
washed deck. Then take care to lay out the new deck with the seams
positioned over the center of the old boards.

Still there could be a problem with moisture from below. Especially if
the old deck is flat sawn rather than quartered. As the humidity on the
back surface changes the old flat or riff sawn teak could cup. That would
put some weird stresses on the new deck.



Potential moisture below the old decking is certainly the area of greatest
concern and may require lifting small sections of the old deck
to search for trouble spots. I would use a polyurethane adhesive rather than
epoxy and matting to allow for any possible movement .
I doubt that cupping would be a factor in a well weathered deck made up of
1.5 to 2 inch teak strips.


Thanks for your opinion..........Ken

I provide teak decking for the DIY folks and have received several
inquiries regarding laying thin (1/4") teak strips over an existing
failed teak deck. Traditionally laid teak decks primarily fail because
caulking separates or the bungs loosen and water corrodes the fasteners
that then enters the subdeck. In theory.... securing all loose decking,
filling voids and then rough sanding the existing teak deck should
provide a sound subdeck to adhere the new 1/4" decking to.

Does anyone in this forum have experience regarding adhering new teak
over an existing teak deck ? Especially interested if someone has done
this 10 years ago.
