The general wisdom is that wood glue sets harder than the original wood, but experiences and testimonies on this seem to vary.
Two weeks ago, I replaced some worn hinge screws on a heavy interior door. I reused the existing screw holes, applying some PVA glue (Titebond III) to strengthen the threads just in case.
I'm examining these screws now and noting that they are holding fast.
However, the threads themselves, though very solid and secure, are slightly gungy and sticky, with a tough treacly consistency when the screws are removed. The glue seems to have penetrated the surrounding wood, altering the material properties of the pine around the threads.
At two weeks, I had expected the timber to be back to its original consistency.
Bearing that in mind, what is the mechanism of action of PVA glue, and what seems to have happened in my case? Can I expect the pine to return to a hard/dry consistency over time?
