How to Make Prefab Bookcases Look Like Built-Ins

1. Trim Back the Molding: If the prefab bookcases have any ornamental moldings, use a pry bar or utility knife to carefully remove the molding. It's usually attached with glue or nails.

2. Prime the Bookcases: Applying primer will help the paint adhere better to the bookcases and make the final coat look smoother. Use a paintbrush to reach corners and trim areas, and a roller for larger surfaces.

3. Paint the Bookcases: Choose a color that complements your room. Use painters tape to protect any hardware and make crisp lines where different colors meet. Apply multiple coats of paint for even coverage.

4. Caulk the Seams: Once the paint is completely dry, caulk the seams where the bookcases meet. This will help create a seamless look.

5. Secure the Bookcases to the Wall: For safety, use L-brackets or braces to secure the bookcases to the wall.

6. Style the Bookcases: Arrange your books, décor, and any other items on the bookcases to create a personal and inviting look.

Additional Tips

- You can add crown molding to the top of the bookcases to enhance the built-in appearance.

- Consider using a decorative wallpaper as the back panel of the bookcases for an extra touch of elegance.

- If the prefab bookcases have visible hinges, replace them with concealed European-style hinges for a more streamlined look.

- Don't forget to adjust the shelves to your desired heights and add any additional hardware like handles or decorative knobs.
