But as I said...
Yellowing of epoxy sounds like it's been left exposed to UV (sunlight), in sunny climes this will occur in as little as 6 months
Epoxy should be painted (or see below)
I'm picturing this application as having the epoxy under
the teak and therefore protecting the epoxy from UV degradation.
If you want the caulked effect of black caulk between teak strips add carbon powder to the epoxy (almost negates UV degradation)
I can't and won't comment on your skill level but Gougeon estimates 80% of all epoxy bond failures are down to incorrect preparation and mixing.
"Rejecting" the epoxy?
The epoxy, properly applied, migrates into the pores of all woods, not far, but upon seperation you will
see some wood embedded in the epoxy.....if it's not then it s.a.s. ain't been applied properly. Applied properly it will tear pieces of wood out with it.
I've even applied epoxy onto teak deck
pieces......3 coats looks like 12 coats of varnish
, a really deep finish.....BUT it needs protection from UV with an epoxy compatable varnish
