I have a wood porch column with the flat square that it sits on is separating at one of the corners. I found some White Lightning 3006 All Purpose Adhesive caulk downstairs but I don’t know how old it is. It hasn’t been opened. Would it be safe to open it and use it on this column? How long should you keep caulk even when it hasn’t been opened? I can't find a date on it so I am hoping someone here can advise me as to what to do.
