Drapery cornice boards add a finished element to your window treatments. A decorative cornice conceals the surface of your drapes, including the hardware. Windows allow heat to flow into and out of your home freely. When you’re trying to decrease the heat movement, and keep your home cooler in the summer and warmer in the winter, heavy drapes help. However, the heavy drapes often create a thermal flow, moving heat where you do not want it to go. A topped cornice board will prevent the flow and boost the efficacy of the window treatments.
Measure the distance from the wall into the innermost layer of curtain stuff. Add 1/2 inch to the measurement. You wish to permit the curtains to move freely without giving the room’s air too much space to circulate.
Measure, cut and mark two legs to your cornice board in the 1-by-4-inch board into the length you calculated. Clamp the board securely to the surface, employing the C-clamps, prior to cutting edge.
Measure the distance between the outside edges of the drapes at the top, and add 4 inches for the period of the front cornice board. In case your hardware extends beyond the edge of the curtains, measure to the outside ends of the hardware rather.
Measure and mark the cut line to the front cornice board employing the measurements you calculated. Clamp the board into the surface, and cut it with the circular saw.
Stand the two legs end and set the front cornice board at the top of them, with one leg at each end. Check that all edges are flush. Insert two 2-inch screws through the front cornice board to the elbow at each end.
Prime the cornice boards, and allow the primer to dry thoroughly. Paint the cornice boards with the acrylic topcoat in the shade of your choice, and permit it to dry.
Attach the four 2-inch L-brackets into the inner edge of each leg with the 3/4-inch screws.
Rank the cornice board against the wall with the help of an assistant. Check that the board is at the appropriate height to conceal the cover of the curtain and the hardware, so it is level. Attach the cornice into the wall with the 1 1/2-inch seams.
