Turn the power off to any electrical receptacles installed in the wall. Verify that the power is off using a voltage tester. If no reading appears on the tester, it is safe to proceed.
Remove the receptacle covers using a flat-head screwdriver. Turn the screws counterclockwise to remove them.
Remove the crown molding from the plaster walls by prying it up and off with an 8-inch broad knife. Work the knife between the wall and the base of the molding, beginning at either end. A stepladder is usually required to reach the molding.
Remove the corner trim and baseboards using the broad knife as outlined in Step 3. Avoid cracking or splitting of the trim by prying a little at a time. If any nails are present, pull them out using the nail remover on the utility pry bar.
Peel the paneling away from the wall at either exposed end, using the pry bar. You can use the broad knife to remove any remaining paneling from the plaster wall surface.
