For use with Background Markers by Mohawk Finishing. The Background Marker dispenses a thin, highly opaque, fast dying, low sheen film to replace background color over fills, glue lines, dark areas in raw wood, and other stains. Indispensable for touch up on MDF, particle-board, and other very absorbent substrates, which go dark with other types of markers. Color band on markers to aid in identifying correct colors.
