Foam molding has a number of different uses and has become more popular as an alternative to wood molding, because it is less expensive. Foam molding doesn’t only have to be used as framing for rooms. It has others uses, such as an inexpensive way to make a window valance.
Step 1 - Measure the Window
Before you cut the foam molding, you’ll need to measure the space around the window where you want your valance to be placed. Measure the length of the window or the length of the curtain rod that goes over the window and add an inch or two for each side. The depth of the valance is up to you. If you have a curtain rod installed, and you plan on covering it, you’ll want the foam to extend out further than the curtain rod. You also need to measure the width of the curtain rod so you can be sure the foam molding will fully cover it.
Step 2 - Purchase Foam Molding
Purchase enough foam molding to match the measurements of your project. Foam molding is much cheaper than wood but still has the same look when the project is finished. Make sure the foam molding is big enough to cover the curtain rod.
Step 3 - Cut Foam Molding
Once you’ve purchased the foam molding, you need a miter saw and miter box to cut the foam properly to form corners. First cut the pieces to size according to length and depth. Then, make two 45 degree cuts that point inward on the piece of foam used for the length of the valance. On the pieces of foam used for the depth, you will cut a 45 degree angle pointing outward on the side that will connect to the length piece. Do not cut the side of the foam molding that will be attached to the wall.
Step 4 - Attach the Valance
Using a strong adhesive, attach the pieces of foam molding to one another. Attach the pieces together before you try to attach the valance to the wall. You can use a level to make sure the corner pieces are flush with one another. Wood molding is usually attached to the wall using galvanized nails, but with foam molding, strong adhesive glue will work. Follow the instructions on the adhesive to attach the valance to the wall properly. Each adhesive varies, and you might need to hold the valance in place for a few minutes before it is ready.
Step 5 - Paint the Valance
You can paint the valance to match the décor of your room, or you can stain it to look like wood. You can choose to paint the valance before you attach it to make sure you cover each bare spot.
