How to Cut Half Round Molding How to Cut Half Round Molding

What You'll Need
Measuring tape
Pencil for marking
Miter saw
Sandpaper

Half round molding can add elegant details to your home. It is used to frame wallpapered areas, create panels on flat walls and add dimension to other trims.

Step 1 - Measure Carefully

Once you have determined how much molding you need, add a couple of feet to your estimation to account for cutting and angling.

Step 2 – Dry Fit the Angles

When you are cutting an angle, take a scrap piece of molding and cut the angle and then put it into position to be sure you have exactly the right angle.

Step 3 - Mark the Trim

Mark this angle and the length on the piece of molding to be cut. Now you are ready to cut.

Step 4 - Cut the Molding

Use a miter saw to make the cuts you have marked. You will usually be making angled cuts (also called miter cuts). The two cut pieces of molding are put together perpendicular to one another to form a 90 degree angle. This allows you to make raised panels.

Step 5 – Fit the Molding

Another cut you may need is an inside corner cut or an outside corner cut. Because walls may be out of plumb, dry fit all of the trim before installing so that you can do any trimming or sanding to make them fit perfectly. When cutting from one length of molding, make the first cut and then measure from the cut end to make your next measurement. Mark pieces before cutting so that you know the exact location for that piece.

Now you are ready to install your trim, and all of your preparation and careful cutting means it will fit perfectly.
