Apply Wood Glue With a Flux Brush
Flux brushes, available in the plumbing department of hardware stores and home centers, are just right for applying and spreading glue. They work especially well for gluing intricate joints like the ones in the coped door rail shown here. You can store a wet brush for a few days in water and then wash and use it over and over again.
Cover Bar Clamps With Wax Paper
When you use steel bar clamps or pipe clamps, and wood glue comes in with the clamp, the moisture in the glue can cause the steel to leave a dark mark on your wood. Lay a sheet of wax paper over the clamps to prevent this “dark spot” problem. It will also catch glue drips that would otherwise get all over your clamps and workbench.
