When you finally reach the stage of staining or finishing your project, the last thing you want to see is blotches caused by glue squeeze-out along the joints. It can be tricky to prevent, too: If you use water to clean up the excess glue when it’s wet, you’ll only spread it around or even weaken the joint. If you try to sand the glue off when it’s dry, it will turn to gum and clog the sandpaper. And if you try to scrape if off when it’s hard, you’ll gouge your workpiece. So what’s a woodworker to do? Let the glue dry about 20 minutes (until rubbery), then scrape it off with a sharp chisel. Use a slightly damp rag to get rid of glue residue. When the piece is dry, lightly sand, then apply a stain and finish.
