Okay, tonight when I was doing one of this week's builds, I noticed something interesting. Two weeks ago was the last time I had built an enclosure, and I finished another on sunday. But tonight, I used an older bottle of titebond 2, and when it dried it was literally white as baby powder. Quite powdery to the touch as well. The joints dried yellow as usual, but the excess (after wiping, not the beads) dried bright white. Why is this? It has been extremely cold, but I dunno if that's it. I'm just wondering because I don't want to be selling shoddy enclosures just because mah glue's gone bad :(

Input? Thanks. :)

I've seen what you are talking about.

Don't think it hurts integrity.

I'm just hoping it doesn't, because the joints were yellow, but the excess turned white. Literally like baby powder white. Weird as hell. I'm thinking that it has to be the cold because I bought it only a few months ago and used it two weeks back when it was mid 40s with no problems, and I've had the same jug of T1 for 8 months and it still works fine (used about 3 weeks back). This is the newest bottle I have, and even when I tried using the T2 from my smaller bottle, the same thing happened.

And BTW it's between 0 and -1 here right now, depending on the station.

TBII did that with my last enclosure as well, and it was **** cold, colder than I've built in before.

Didn't seem to mess with the strength of the bond, but it DID take more than twice as long to cure....

All my excess glue turned white, i kinda wondered the same thing myself. Kinda odd, but i didn't think anything of it. Probably the cold. It's like 2 degrees here now with like 7 inches of snow on the ground.

Its because of the cold weather :fyi:

If you read the bottle...says something like don't use under a certain temp.

Yeah, 40 degrees IIRC.

Yeah, happens when it's cold. Usually if any extra glue falls on wood, you can use a damp cloth to wipe it completely clean off. When it's cold, it leaves a nasty looking white patch.

And yeah Pat, that basically describes the situation.

Under 4 degrees? You must be a diehard sub box builder. hell i thought i was bad. my dad parks his truck in a big 80 x 40 foot shop and it stays around 40 degrees in there, just to keep **** from freezing. and i cant stand it.

if it was because of the cold, the joints and the excess would be the same color....since they are the same temp. i think it is because of it's thickness in the joints...the thicker the more yellow it will appear.

yeah, my a$$ is tired of shoveling here too....dam snow blower is in the shop.

It's not THAT bad, because I have a heated garage, but the heater's been broken, so it isn't heated right now. Box needed to be done by today, and if UPS hadn't ****ed my delivery of carpet, it would have been done yesterday.

And I just checked the joints again this morning. Theyre hard as usual, but indeed are powder white. This better not **** it up, or I'll be a little unhappy :(

It's the cold man.

When I lived in Idaho, for the most part it was lower single digits throughout december and part of jan. I tried to build one box in the cold, and the glue just turned white and wouldn't really cure well (original titebond).I ended up building most of that in the dining room and garage instead of the shop.

Got it. Installed it today, but found another problem which is completely unrelated. It's in the electrical section.
