Prep the bead board surface by gently sanding the wood with 150 grit sandpaper. The surface of the bead board needs to be clean for the glaze to set well.
Wipe the wood dust from the bead board with a dry cloth.
Choose a three- or four-inch synthetic paint brush and soak the bristles in water, then saturate the brush as if you are about to paint with the water. Dry excess water from the brush because you do not want to dilute the glaze when you begin glazing the wood.
Dip the paint brush bristles halfway inside the water-based antique glaze and apply glaze evenly to the bead board surface. Saturating the entire brush with glaze will ruin the brush over time.
Allow the glaze to dry for an hour before re-sanding the bead board with the 150 grit sandpaper. Sand lightly in some areas and heavy in others so when the next coat of glaze goes on it gets that antique looking effect.
Apply another coat of glaze to the bead board and allow it to dry for an hour.
Seal the bead board with a coat of water based lacquer and allow to dry overnight.
