Gorilla glue foams up to much. Air bubbles add no strength. It also doesn't
stick to everything.

Try West Epoxy and a syringe.

As a general rule use the best glue possible for the job. Otherwise, the
second time you do the job (and you will) you'll have to remove all the
glue.

Check the 3M website for adhesives. They have some amazing stuff. The had
some spray adhesives that held fiberglass together at over Mach 1 on
aircraft wings. (The fiberglass was not structural, it was an aperture). The
same glue could be used to adhere Katy to the outhouse seat.

Glory!

Questions:

I have an old Laser which has a hull/deck flange. The bond is lost along
quite a bit of the flange.

Do you mean that the the flange is damaged, big chunks torn out of it, or
that the area of the bond between layers is gone soft & cheesy?

.... It appears that someone attempted to rebond it with epoxy at one
time, but unsuccessfully.


It was probably considered successful, at least for a while.

My questions are these: 1) Since polyurethane adhesive, such as 3M 5200,
is often used as a hull-to-deck bonding agent on larger boats, wouldn't
polyurethane be suitable for a smaller boat, too?

Yes. A lot of people like Sikaflex better.

.... 2) The space between the two shells along the flange is too narrow
to get something as thick as 5200 to flow into it. Since Gorilla Glue is
a polyurethane adhesive, any reason it wouldn't work as well? It would
flow nicely into the space and it expands when it cures, which would fill
the space nicely.

Any opinions or experience with Gorilla?


I haven't used Gorilla Glue much, and IMHO it isn't really very strong (so
I don't plan to use it in the future). It does not fill gaps very well
either (again IMHO), seems to foam up.

The best way to repair a hull/deck joint is to seperate them and re-attach
them along the full length. Yes it's a PITA. But if you need a project for
a long winter, it's great. At some point along the way, you'll be telling
yourself 'it'd be easier to just build a d^%% boat from scratch' which
tells you you're on the right track.
