I am putting a new deck on a wooden boat, but I need advice with respect to treating the underside of the desk before I glue it.
The desk framework has been repaired, and the wood varnished except for the surfaces that will glue to the underside of the new deck. I am putting on a new tiger strip ply so want to ensure the underside does not absorb no / minimal moisture (cost to much to ruin) . I would normal think of just straight varnishing on the underside before I glue, but my concern is ensuring that the epoxy will form a good bond and that the varnish will in effect get in the way.
Any advice on how to treat / seal the underside of the deck before I start gluing.
Thanks in advance.
