Separate the stained piece you want to glaze from any objects to which it is attached. For example, if you want to stain a cabinet door, detach it from the cabinet first and remove any knobs or anything else that you don't want to glaze. Place it on a sheet or in a work area that you don't mind getting messy.
Clean the piece thoroughly, unless it has just been stained. Dirt and grime can mix in with the glaze and ruin your look. Make sure it is dry before you begin glazing.
When mixing paint with the glaze, use brown, black or gray for a more authentic antique look. Use a high ratio of glaze to paint (three parts glaze to one part paint) for a lighter antique finish, a one-to-one ratio for a medium finish and a paint-heavy ratio (three parts to one part glaze) for a dark antique finish.
Dip the rag into the mixture and use straight or circular strokes when applying, depending on your preference. The streak marks will show up in the finished product. Make sure you get it in all the cracks for a complete look.
Work in sections, as glaze dries quickly. Use a clean cloth to remove excess glaze. If you wipe off too much, reapply until you get the look you want.
When you are finished, let the piece dry completely before reinstalling the piece or putting it back where it was for regular use.
