Follow these steps to install crown molding based on its fit against the ceiling:
Tightly Fitting Crown Moulding:
• Use brads or a nail gun to secure the molding directly to the ceiling.
• Ensure the brads or nails are driven securely to hold the molding in place.
Crown Moulding Not Fitting Tightly:
• Secure the molding to the frame from the inside using screws (not included).
• Pre-drill holes into both the frame and the molding to prevent cracking and facilitate easier installation.
