That moment my glue joint failed 3 hours into a restoration
I was at my bench last Tuesday working on a 1920s poetry anthology for a client, the spine was completely detached and I thought I had it all figured out. I used my usual PH neutral PVA and clamped it tight, left it for about an hour before I took the clamps off to check. The moment I opened the cover the whole thing just popped loose like it was never glued at all, I was so frustrated I almost threw it across the room. Turned out I had forgotten to rough up the spine lining with some sandpaper first, the old glue residue was too smooth for the new bond to grab. I ended up scraping everything off, roughing it up good with 80 grit, and redoing the whole job the next morning. It held perfect after that and the client picked it up yesterday happy as can be. Has anyone else had a similar fail where the prep work was the real issue, not the glue itself?
