Thick wood glue? lose water/gain mass
 
Hi, I found practical use for thick wood glue, is that unusual for a woodworker? I put some glue in a tupperware, and let it there seat for some hours, until it loses the desired water quantity.

At certain grade, it would be ok and reliable to mix with any other stuff, so it gain some mass, for example, wood dust, a very nice way to make a wood filler.

The reason of posting this, is to get info about any other stuff you can mix with wood glue, for example, industrial talcum powder? I saw a guy using talcum when making a kind of wood primer.

Ive tried the whole "wood glue and sawdust wood filler" a few times, and its always been way more trouble than its worth. The improvised mixture doesnt absorb finishes in the same way as the surrounding wood, so it stands out something fierce.

As far as other stuff you could mix with it, im sure theres plenty of stuff you could technically mix, but why would you want to? Wood glue's purpose is bonding wood, using it outside that purpose is going to result in a subpar end result

Why would you want the glue to thicken before adding a foreign substance?

The problem with thickening the glue is the drier it gets the less adhesive qualities it will have.

I, too, have made glue/saw dust fillers. I've used them with some success to fill large gaps. But I always ADDED water before and while mixing in the sawdust. I wanted the mixture to flow down into the gaps, to bond to both sides of the gap and to fill it up. Dryer the mix, the less that's going to happen.

One thing I strongly advise AGAINST mixing with wood glue. Do NOT mix wood glue with your hair. Don't ask me how I know, but I do know the only thing the mixture does well ... gives reason for a new hair style.

If your using wood (white) glue as a wood filler it is able to be done by adding sawdust...BUT...as already said, it lessens the adhesion quality of the glue. Anytime you mix something in a prepared glue you offset the original chemistry it was designed for.
Allowing it to thicken by sitting out also lessens it's designed adhesion qualities.
When I'm joining wood together, I want all the stick'em I can get.

Yes, that's what I thought, but also thought in preparing the contact area by first applying some non treated glue before you put the new compound.

It sounds reasonable to me to apply only glue first to the contact area.

Personally I never cared much for homemade putty. They had us use it in high school shop but once I got out of school quit. The stuff takes too long to fully cure and shrinks so much you often end up having to putty twice.
