This was in reference to
a deck repair - what glue to use to apply
teak planking to a plywood substrate. It makes general
comparisons between the glues
Epoxy is gap
filling - so if there are gaps between the ply and the deck
substructure the epoxy will have no problems.
With a deck done in this way you don't need to use any
permanent
fastenings (screws or nails). You can use gyprock screws put in with a
battery powered drill (one with a clutch) - and pull them out when the
glue has set up. Plug the holes with epoxy and glass or dynel. I
usually use glass when I do decks (not on small sailing dinghies though
- too heavy)
Resorcinol is a very fine glue when you can make sure the
fits between
surfaces are good and can get high clamping pressures. It is a dirty
brown colour and tends to stain. All exterior/marine/aircraft ply is
glued with resorcinol.
There are gap
filling resorcinols around now, but they don't seem to be
commonly available. I would suspect that they are not as gap
filling as epoxy and are still the same old dark colour.
