Construction Adhesive

[crokett]

Are there any reasons not to use this for general woodworking? After trying to undo mistakes in the past with it I can tell you it is strong stuff. I've thought about just starting to buy tubes of it and use it for my woodworking.

How and on what are you planning to use construction adhesive?

I've used it on few construction projects around the house, but seems to me it would be too thick for general woodworking joinery.

That would be my first thoughts too. But you're right....the stuff is definitely strong! If you use it, give us some feedback.

I agree with Mike. I can't imagine trying to spread a think layer of it on a joint. Plus it generally stains pretty bad even if you clean it up quickly.

I guess there are a few places it could be used like corner support blocks, but I don't think you could easily use it for anything that may be visible. It would be tough to control and it would be really bad to clean up the sqeeze out.

[radhak]

don't do that!

the biggest problem would be that as soon as you say you used construction adhesive on any woodworking project, it becomes a construction work and you become a carpenter from a woodworker, and we all know what a no-no that is

I dunno yet. One application I was thinking about was inside dados for instance. Another is laminations. I just know I've split 2x4s in half trying to get them off a concrete floor after being glued down in the wrong spot. Squeeze out is going to exist with any glue. Beside which it seems to me I could tool a thin layer of adhesive on wherever I needed it. But if there's silicone or something in it that might interfere with a finish then I would not use it.

I would use it on only relatively crude projects that will be painted. It is better at gap filling than yellow glue though not as good as epoxy. If you joint doesn't fit real well, it could be handy as long as it will not show in the finished piece. I have also used it like caulk around the inside corner joints of sterio speakers to make sure they were airtight. I think it has some application in the shop but yellow glue is cheaper and more useful for most things.

Construction adhesive is more akin to epoxy in that it fills gaps but does not flow well. Yellow glue produces best results when it is only about one molecule thick, this molecule forming a chemical bond with wood on its either end - hence you want surfaces very smooth, perfectly fitting, and you need clamping pressure throughout to maximize the contact surface. The result is a glueline that is pretty much invisible - especially when grain is well matched. Good luck getting an invisible glueline with construction adhesive. Using it in dadoes, and other places where gluelines are out of sight is fine, but using it to glue up a door panel, a tabletop, a bent lamination or a row of dovetails is something you definitely don't want.

I used it to repair some chairs for the library. Told them if they ever come loose again just throw them away. So far they are holding up very well.

Good points all. Another thought was that if I put it in a mortise I doubt the mortise would ever fail. If I use it I will let you know the results.
