Learned that upper 40s (near 50) is too cold to glue! I had glued a frame together inside and was adding splines. It looked like I had white paint on the walnut. 😲 I looked up what was going on and found it was likely too cold so there was "chalking" with the glue. This is the definition from Titebond: "Chalky white appearance of a layer of glue which has dried too cold. A glue which dries below this critical "chalk point" does not knit together properly and the resulting bond is likely to fail."
My splines seem ok, but lesson learned. Hope this might help someone else who might try to push the temp range for gluing. This shows the white on a cut off And what it should look like
I've dealt with that before, really sucks! Currently I keep my glue inside and if I plan on gluing the next day I'll bring in the wood too. Shop is usually about low 50's when I step in and it takes an hour for the wood stove to get it up into the mid 60's. The wood needs to be warm and that would push any glue ups into the afternoon if I hadn't brought it in.
The glues I have all say that glue and materials need to be 55+ except for TB3 which goes down to 50.
