How to Build Up Crown Molding for Furniture

Building up the crown molding detail on a furniture project adds elegance and character. Whether you are building an antique hutch or a contemporary bookshelf, the project is never quite finished until a proper crown detail has been installed. The process of crown buildup is simple and cost-effective because the build-up material is much less expensive than crown molding. Many different kinds of molding can be used as build-up material, but the most widely used is called sub crown molding. Sub crown is a molding like baseboard molding or casing that has been reduced in width to fit beneath crown molding.

Instructions

    • 1

      Establish a logical direction around the project like an armoire or bookshelf; start at a specific place and work your way from that starting point to the end.

    • 2

      Install the sub crown molding around the sides and front of the furniture piece. The sub crown should be glued and nailed to the furniture cabinet 1/8 inch to 1 inch above the doors and other details. The proper distance can be determined by matching other cabinet-to-detail distances.

      Install the crown molding to the sub crown molding.The crown should be glued and nailed to the sub crown as well as to itself at the miter junctions. Nail through the lower profile detail of the crown molding directly to the underlying sub crown molding.

      Fill all nail holes and molding joints with wood filler.

    • 5

      Sand the entire crown build-up detail with 120-grit sandpaper, paying particular attention to the areas where wood filler has been applied.
