PU glue should be fine for screwed and glued joints. I use the PL Premuim
construction adhesive that way. With the feinforcment of the wood screws it
fills gaps just fine. It acts as an adhesive bedding. I've also removed
the wood scews after the glue has dried on 2 small boats (bottom skids)
and have had no sign of separation in 3 years. The boats are stored
upside down outside exposed to weather. They don't spend much
(enough) time in the water.

Thanks for the input. Thanks also for pointing out how to search for
previous posts on the subject. I don't like to be a bother with "newbie
questions". I'll certainly check first before being redundant. I'll be using
PU adhesives for now on with good fitting joints, as it is so nice to be
able to use "straight out of the bottle" versus mixing up a "little bit" and
scrambling trying to find a place to "use" the leftover. Thanks again!

What exactly is PL Premium...Something I can find at Home Depot?? Thanks.

Do not use it. DO NOT USE IT. I used it for my two MiniCups and now
regret it. It has no strength in gap filling. It loses its strength
after prolonged immersion (like if you get water in a floatation tank).
Use epoxy instead.
I essentially had to take apart my MiniCups;
one nearly fell apart due to the Gorilla Glue weakening, to remove the
weakened Gorilla Glue and to fillet all the joints with epoxy.
I have used Gorilla Glue to repair chairs and within a month they
needed to be repaired again. I then used epoxy and they are solid
months later.

Joints which were glued with Gorilla Glue and then screwed together (on
the boats) easily came apart by prying, the glue failed. I was
horrified when I saw how weak this stuff is.

If the joints were that weak, the screws must not have clamped them
tight enough and the glue expanded. The same is probably true of your
chair repairs. With tight joints, the wood will fail before the glue
does. You CANNOT use PU glue to fill gaps; it says that right on the
bottle. Epoxy is definitely more forgiving and does fill gaps well, but
you can't blame the PU glue if you use it improperly or in the wrong
application.

But the problem with boats is that you cannot make tight joints most of the
time. It's almost impossible to apply 4kg/cm2 on a joint which is several
meters long.

So true. If it weren't for the precision fit on the cheap boats I throw
together, PL Premium would have failed. Maybe my aim is a little better
than Mini-cup builders. Not by much I'd wager. PL Premium expands, fills
gaps, and holds just fine thanks. I've never had to mix it with any kind
of filler as I do with epoxy and did with "plastic resin".

Fine, then use an adhesive more appropriate to the task.

Over priced and under peckered.

Strictly garbage IMHO.

Yes, but what do you really feel? Don't hold back now.

I agree. Another miracle product bites the dust.
