Coping Joints

Make your joints fit the way the pros do. 

Coping joints are used instead of mitered inside molding joints because they do not open up when you nail them and changes in humidity will not cause them to open and close as noticeably.

1. Cut the first peice to fit butted into the corner.

2. Measure the adjoining piece as if it was to be butted to the wall, do not take into consideration the width of the molding that is installed.

3. Make an inside 45° cut on the adjoining piece, then with a coping saw cut along the profile created by the miter keeping the blade of the saw perpendicular to the molding. Adjust the fit by sanding or trimming with a sharp utility knife.
