instructions. The types of materials that i tested were those that
the label said it would successfully bond.
My reason for testing this glue is because it is the first readilt
available 'Waterproof' glue in our area . Ive always had to have
stuff sent from Perth,600kms away by mail.. All other non epoxy
glues Ive tried have been unsuccessful. This latest stuff is actually
more expensive than the epoxy that Ive been using. Today I started
on the hull of a new landyacht and found the glue excellent to work
with. as long as you wetted both pieces of wood ( the instructions
said one side)5 minutes before and then just before applying the glue.
I'm glad i did the tests first.

Be careful when speaking about polyurethane glues (and polyurethanes
in general) not to be overbroad in one's generalizations. The
polyurethanes are one of the most diverse molecular groups used in
plastics, and properties can vary all over the map. Gorilla Glue is
different from PL Premium which is different from PL Construction
Adhesive which is different from Borden's or the numerous Ren/Ciba
Geigy products. As far as I know, all single-part types are moisture
cured. But keep in mind there are also 2-part polyurethane glues (and
elastomers that can effectively be used as glues) and *typically*
these should be used in the absence of moisture. *Some* of these are
so moisture sensitive that they cannot be used on wood, others are
not so picky.
I've used PL Premium extensively on two plywood boats with excellent
results, always working in a humid climate (Florida and northern
Mississippi, USA), simply following the package instructions.

You can use sheetrock screws as clamps if it's in an area where the
appearance doesn't matter.
I can't say much about the metal adhesion properties but have glued rubber
to brick with it quite successfully.

Polyurethane glue has finally arrived in kalgoorlie. When i was
building the schooner i couldnt get it for love nor money. Now
Selleys have it as Waterproof Aquadhere.
I bought some to test it. 5 tests. wood to steel-no good, wood to
aluminium-no good. wood to wood lightly clamped-no good. wood to
wood ,tight fit,heavily clamped. very strong. hit it with a 5 kg
hammer without breaking the bond. I have a final block sitting in a
bucket of water to test later this week. Be warned ,this stuff oozes
foam everywhere so there is lots of cleaning up to do.
I'm going to use this glue to build the new landyacht. if it is no
good thats ok as i intend to sell the boat straight away.
Cheers paul
