Question: can pva glue be sanded?
Answer: I use 180 and then 320 grit when sanding these glue lines. Most or all of the PVA (Poly Vinyl Acetate) white and aliphatic resin yellow wood working glues are somewhat rubbery when you try to sand them. ... In both cases only the final smoothing sanding should be done with folded over "loose" sandpaper.
