How to Install Polystyrene Crown Molding

Installing polystyrene crown molding can be a rewarding DIY project that adds a touch of elegance to any room. Polystyrene molding is lightweight, easy to work with, and comes in a variety of styles and colors. Whether you’re looking to update your home or add a finishing touch to a new construction project, here’s a step-by-step guide on how to install polystyrene crown molding like a pro.

1. Gather Your Materials and Tools

Before you begin, make sure you have all the necessary materials and tools. You’ll need:

– Polystyrene crown molding
– Molding adhesive (such as polyurethane or construction adhesive)
– Caulk gun
– Utility knife
– Measuring tape
– Level
– Hammer or mallet
– Paint or primer (if desired)
– Sandpaper (if desired)

2. Prepare the Wall and Molding

Start by cleaning the wall surface where the molding will be installed. Remove any dust, dirt, or old paint. If the wall is painted, consider priming it to ensure the adhesive adheres properly. Also, check the molding for any damage or imperfections and trim it if necessary using a utility knife.

3. Measure and Cut the Molding

Measure the length of the wall where the molding will be installed. Add a few inches to the measurement to account for any cuts or corners. Use a saw to cut the molding to the desired length. If you’re dealing with corners, you may need to miter the molding to fit snugly.

4. Apply Adhesive

Apply a thin, even layer of adhesive to the back of the molding using a caulk gun. Be sure to cover the entire back surface, but avoid applying too much adhesive, as it can seep out and cause a mess.

5. Install the Molding

Starting at one end of the wall, press the molding firmly against the ceiling and wall. Use a level to ensure the molding is perfectly horizontal. If you’re dealing with corners, make sure the molding is square and fits snugly against the adjacent wall.

6. Secure the Molding

Once the molding is in place, use a hammer or mallet to gently tap it into position. Be careful not to apply too much force, as this can damage the molding. If necessary, trim any excess adhesive with a utility knife.

7. Caulk and Paint

After the adhesive has dried, apply caulk to any gaps or seams between the molding and the wall. Once the caulk has cured, you can paint or prime the molding to match your room’s decor.

8. Final Touches

Inspect the installed molding for any imperfections or gaps. Touch up any areas that need attention, and enjoy your newly installed polystyrene crown molding.

By following these simple steps, you’ll be able to install polystyrene crown molding with confidence and add a touch of sophistication to your home. Happy DIY-ing!
