How to apply shellac
Prepare the area for finishing by sanding it smooth.
Use a coarse-grit sandpaper to go over the entire piece. If there is an old finish applied to the wood, make sure to sand it away completely.
After sanding, wipe the piece down with a clean cloth to remove any dust and dirt. Pour some of the shellac into a separate bucket.
