Tried using a PVA glue mix on a repair and it went kind of gummy
Honestly, I was fixing a 1920s hymnal for a client and mixed my usual Jade PVA with a bit of water to thin it, about a 4:1 ratio. I let the spine dry overnight in my shop, but it stayed tacky and flexible, not firm at all. Ngl, I think the humidity here in Savannah messed with the cure time. Has anyone else had this happen with a specific glue in damp weather?
