I have had a big bottle of tite bond laying around for about 2 years. I used it to build my sub boxes. It is closed. Does it lose its power after a while or is it safe to still use it to build a few sub boxes again?
Storage life is 24 months at 75 degrees F, your garage probably is not so consistent but the glue is freeze/thaw stable. Before you throw it out try gluing a couple scraps together, if the consistency is good and it dries and holds well it should still be ok.
