In order to cut molding properly, you will need the right tools and the right amount of patience. There may be many reasons why you would want to cut your molding while it is still on the wall. For example, you may be trying to fit a piece of furniture against the wall and the molding is getting in the way. The extra couple inches that the molding takes up may be too much for you and you will need to cut a section away in order to make your furniture sit flush against the wall. If this is the case, then you will be happy to know that you do not need to take entire sections of molding down to cut it. Below is a full step by step instruction list on how to cut the molding while still attached to the wall.
Step 1 - Clean the Molding
Before you start to cut through the molding, clean it to make sure you have removed any dust or grime that may be on the molding. Just use a gentle cleaner or a little soap and water with a damp cloth.
Step 2 - Mark the Molding
Using a fine pencil, mark the location on the molding where you want to make the cuts. Measure it a couple times to make sure you are as accurate as possible with the piece that you want to remove.
Step 3 - Score the Line
Take your utility knife and gently score over your pencil lines on the molding or the baseboard. Make gentle depressions into your molding using the knife. If you run your finger over the area, you should feel the scores or depressions you just made with the knife.
Step 4 - Cut the Molding
Before you cut the molding, drape a drop cloth on the floor and cover any furniture that is near by. Cutting molding will create some dust and dirt and you will want to make sure that your other surfaces are protected. Using a pull saw, gently cut along the line. As you cut along the line, hold the saw vertically. Pull up gently as you saw the line. Do this with each stroke of the saw.
Step 5 - Pull the Molding Off
Score the back of the molding against the wall. Push a putty knife between the molding and the wall and gently begin to pry it off the wall as you continue to make your saw cuts. Pull the molding off.
Step 6 - Spackle and Paint
Spackle any portions of the wall that you have damaged in the process. Sand down the wall and the molding edge and paint to restore back to the same color and the finish. Clean up your work area and move your furniture back to the proper location.
