Glues
I think the waterproof vs water resistant glue issue is something of a
moving target. In the real world glues are on a continuum of water
resistance. Test markers are, though *in theory* based on realistic
points of resistance. I said *in theory* because glue
manufacturers/distributors/etc. have to practice some degree of CYA
when making claims. I had contacted the tech department of Henkel to
discuss the water resistance of PL Premium and got a bit of "wink,
wink, nudge, nudge" when they stepped back from listing PLP as water
proof. At one point they actually commented that they would be
entering into dark waters as it were by saying that a dry land
construction glue would be suitable for use in a marine environment.
Case in point Loctite® Outdoor Wood Worx, which they told me was the
same as LePage's Weather Grip® Outdoor Wood Glue, "Exceeds type II
test for water resistance". They just couldn't say waterproof or as
good as TiteBond III.
On a side note, Henkel distributes LePages/Loctite and Duck product.
One of their newer products is Pl Premium Liquid which AFAIK is
presently distributed only in Canada. As they describe it "PL Premium
Liquid is super strong, 100% waterproof, flexible, has low odour,
paintable and fills gaps." Odd they'd call this waterproof when in
fact it's practically identical to PLP. BTW - you can clean up with
water when the glue is fresh. I've tried it on indoor and outdoor use
- works as advertised. Can't speak to long term use but imagine the
gap filling, waterproof qualities of PLP in a liquid form that's as
easy to apply as carpenter's wood glue.
