Water-based construction adhesive
Has anyone used one of the water-based construction adhesives and had good or bad feelings toward it?
I just received a case of no-name secret stuff from Truss Joist for testing on subfloor/TJIs. It’s supposed to have properties superior to the other water-based formulas as well as equaling or surpassing the majority of solvent based construction gooes.
Destruction tests apparently pull the wood apart and not at the glue/wood interface. No idea if it is technically a structural adhesive (no long-term creep or breakdown under load) or just a squeak preventer.
It’s supposed to go on well in damp or rainy conditions (within reason) and actually wash out of clothes. In wet conditions the squeeze out can turn whitish or look washed out, but it’s not an indicator of a poor wood-to-wood bond.
The limitations seem to be it’s only a subfloor adhesive and not suitable for other applications. It’s also not freeze-thaw stable and isn’t recommended over frost covered joists. The tube also recommends no heavy traffic on the floor for 24 hours.
My guess is it would work fine with interior (low moisture) applications that have a fairly tight wood-to-wood contact. It may be sort of like a gooey green carpenter’s glue for subfloor, although I have no idea what it’s made of. On the other hand it might not be worth a darn for anything other than subfloors.

That sounds interesting, I'm interested to hear how it works. I think that being stronger than wood (framing lumber or osb anyway) is basically a minimum for a glue these days. And I definitely like how a good construction adhesive can fill gaps and still be strong.
How fast does it set up, I wonder? I usually like PL's long open time. But I curse the way it oozes out of a tube onto clothes and hands, and never comes off afterwards.

I'm under the impression that it takes a while to set up. Max open time before putting the pieces together is a full 30 minutes on the directions.
We'll deck the second floor of our project on monday and get to try the stuff.

Today we used the water-based construction adhesive and it was interesting.
On the plus side it's much easier to dispense, about the consitancy and color of acrilic caulk. Panels are easier to position and when the tounge & grove have a small bead added (per mfg. instructions) the sheets go together much easier than with traditional goop. At the end of the day our hands weren't covered with dried on glue.
On the negative side, it shouldn't be used near freezing and a cold snap will keep the temps between 20 and 35 for the next two days so we are probably pushing things to even use it today.
We'll have to get another case of the normal stuff to finish the job, which is a little inconvenient.
It would be nice if the stuff was colored to match the wood since having a substance that looks like white caulk dripping down some of the joists just doesn't seem right.
If it were priced the same I'd use it over traditional products in warmer weather since it does make decking go slightly faster and the hastle factor is less.

Thanks for the good info. I'll look for the stuff. Did you say you got some pre-release, or is it widely available?
Where I'm at now, it sounds like it would work fine. Where I plan to be in a few years, the no-freezing thing could be a problem, like your climate. It's a pain not to be able to leave things in the truck overnight.zak

If it is waterbased, long set up and cure, Is it one of those Califoria VOC deals? What good is it for other than non frezing months? Solvent based adhesives also have restrictions. We keep all of our adhesivies indoors this time of year. Even in the south.Sounds like a good product. Do you have a link?Chuck Slive, work, build, ...better with wood

Not much other than taking up storage space in my pantry. :-)

Unfortunately, the tubes are only labled "Test Product" and a number that doesn't correspond to anything I could google up.
A Weyerhaeuser rep asked if we wanted to test the stuff. We get as much as needed for our current project and simply give a little feedback on what we thought of it. The guys at test central are hoping for bad construction weather since they know it works well under ideal conditions. :-)

"...hands, and never comes off afterwards."isn't that the point of using glue?;)

We use a Titebond brand solvent-free construction adhesive for subfloor, sheathing, drywall, etc. It works just like liquid nails except without the killer fumes which can be quite intoxicating when used indoors. Consistency wise it's similar to regular construction adhesives but is water clean-up.
We use water based glue to bond the particle flooring to the joists its easier to use not as messy , we also apply the glue to the tongue and groove joins to bond the sheets and to stop the joins squeaking i have found that if we get a bit of rain it can wash out the glue and the joins aren't bonded so we have gone back to polyurethane for the edge bonding.We also tape our joins to stop them peaking.http://www.johnwalkerbuilders.com
More details, please! What kind of adhesive is that? (Brand) What kind of tape do you use? What kind of floor underlayment is that? Thanks!
