Polyurethane molding looks just like wood molding.
Crown molding is installed along the top edge of a wall where it meets the ceiling. It adds a polished look to the room and complements the surrounding architectural details. Polyurethane crown molding looks almost identical to wood molding but is made of a lightweight, resin foam material. Because the molding weighs so little, it can be installed by a single person. In addition, polyurethane foam can be cut quickly with a manual saw.
Instructions
1. Place a ladder in the corner of the room where you'll begin installing the .
2. Place the end of a tape measure flush with the top corner of the wall where it meets the ceiling. Stretch the tape measure out horizontally and measure as far as you can along the wall. Make note of the measurement and draw a small pencil line at the farthest measuring point.
3. Reposition the ladder and begin measuring from the pencil line all the way to the end of the wall. Add up all of the measurements to arrive at the total length for the crown molding.
4. Lay a piece of polyurethane crown molding on a worktable and measure out to where you need to cut it, based on the measurements you took in steps 2 and 3. Mark the area with a pencil line.
5. Place a miter box on top of the work surface and use a tape measure to adjust the two horizontal guides on the inside of the box to the width of the crown molding. Some miter boxes do not have horizontal guides.
6. Insert the polyurethane crown molding in the miter box so it's positioned upside-down. Press it firmly against the back of the box so there are no gaps.
7. Adjust the front angle guide on the miter box to 45 degrees on the right side of the box if you're cutting an inside corner, and 45 degrees to the left side if you're cutting an outside corner.
8. Insert a handsaw between the two poles on the front and position the front of the blade on the crown molding.
9. Move the saw in forward-and-back motions until you cut all the way through the molding.
