titebond iii & wax paper vs. tablesaw


For a recent project I had to glue up walnut legs. In my very small shop the table saw usually ends up the surface of choice for doing this. I layout a sheet of wax paper to protect the top from the glue up and minimize the amount of my barrier sticking to my project because of squeeze out. This has worked very well up until the walnut. I glued the parts using tite bond III, had a normal amount of squeeze out and left to dry over night.
In several areas where the squeeze out had set between the walnut and wax paper it had leeched or eaten through the paper. The glue had absorbed some of the wax and turned a dark purple/black with the consistency of melted crayon. Some steel wool cleaned up the table saw and a quick 1/32" pass through removed any trace of the stained glue on the surface of the wood. So all ended well but, any ideas what would have caused this?

go to a fabric store and buy a nice sheet of thick waterproof upolstery. That's what I use to cover my bench when doing glue ups and finishing. Get a piece big enough to cover your surface. Fold up when done. Lasts forever (even though it gets kind of ugly). In the long run, it saves you from buying all that wax paper.

I use a cheap plastic table cloth. Mine were kitchen rejects from when the kids were young, so they started out ugly. New ones cost a buck or two at a discount store, have a soft felt-like backing, cover the entire top, and a bright flower pattern will add just the right touch of color to brighten the shop...

Is there any chance that there was a residue of somethign like WD-40 or mineral spritis on the tablesaw top?
If not, the culprit would seem to be the walnut itself. Could you try glueing some scraps to see if the effect is reproducible on a different surface?

I haven't contacted titebond but that's a good idea. The only thing on the top is a coat of Johnsons paste wax. I've been using that for years coating it about every six months or so with very good results. It was about 3 months since the last coat.
Thanks for the ideas. I may indeed beef up the gluing barrier to something more substantial.
