How to Install Crown Molding | HGTV

Introduction

This tutorial will guide you through the process of installing crown molding, a simple yet effective way to enhance the aesthetic of any room in your home. With the right tools and techniques, you can achieve a professional-looking installation that adds character and charm to your space.

Step 1: Gather Your Tools and Materials

Before starting the installation, ensure you have the following tools and materials ready:

• Crown molding
• 18-gauge nails (2.5 inches)
• Nail gun
• Paintable caulk and caulk gun
• Ladder
• Miter saw
• Tape measure
• Safety glasses

Step 2: Understand Crown Molding Cuts

Familiarize yourself with the three main types of crown molding cuts:

1. Inside Corner Cut

   • Bottom edge is long, top edge is short.
   • Mark the wall measurement on the bottom of the molding.
   • Draw a line indicating the angle of the cut.

2. Outside Corner Cut

   • Bottom edge is short, top edge is long.
   • Measure wall for the bottom of the molding.
   • Mark and cut similarly to the inside corner.

3. Scarf Joint

   • Used to join two pieces on a long wall.
   • Measure the wall and cut at a 45-degree angle without flipping the board upside down.

Step 3: Make the Cuts

Inside Corner Cut

• Measure the wall where the molding will sit.
• Flip the molding upside down.
• Align the molding with the saw and mark the cut direction.
• Set the saw to a 45-degree angle and make the cut.

Outside Corner Cut

• Measure and mark the wall.
• Flip the molding upside down and align it with the saw.
• Set the saw to a 45-degree angle, following your marks, and cut.

Scarf Joint Cut

• Measure the wall to the lowest point.
• Lay the board flat on the saw.
• Tilt the saw blade to a 45-degree angle and cut both ends of the boards.

Step 4: Install the Crown Molding

• Fit the cut pieces snugly together at the corners.
• Use a nail gun to secure them in place with the 18-gauge nails.

Step 5: Fill Gaps and Nail Holes

• If there are small gaps (especially in inside corners), use paintable caulk to fill them.
• Apply a small bead of caulk and smooth it with a damp rag.
• For outside corners, ensure a snug fit as caulk won’t cover gaps effectively.
• Fill any visible nail holes with caulk for a seamless appearance.

Conclusion

Installing crown molding can significantly upgrade the look of your room. By following these steps—gathering your materials, making the correct cuts, and ensuring a neat installation—you can achieve a beautiful finish. Once completed, consider painting the molding to match or complement your room decor. Enjoy your newly transformed space!
