Default polyurethane adhesive

Would you guys agree on the use of one-part polyurethane adhesive
instead of two-part epoxy with filler for gluing several (4) pieces of
1" teak wood planks in order to make a properly shaped base between the
windlass and the deck?


No. Polyurethane glue has no place in a boat in my opinion. First, it needs
a high clamping force of 4kg/cm2 or 60lb/in2 for a reliable bond. Do the
math for any serious area....

Second, it has no gap filling properties. Yes, it fills gaps with foam, but
without any strength. You need to have a very good tight fit.

Epoxy on the other hand can be "slapped on" and you can just lay the pieces
together and still obtain a bond far better than with poly goop.
