To Install Baseboard Molding to Concrete Walls, you have to Place the baseboard molding that you want to use in the basement for at least two days. After that, Measure the walls where the molding will be installed. If the walls meet at an outside corner, you need to add the width of the molding to the figure. Then, Cut a piece of baseboard molding for each wall using the measurements you found with using a saw. Next, Miter any pieces that connect at an outside corner to forty five degrees using a miter saw.
Forth, apply a thin layer of construction adhesive to the back of the molding. After that, Press the molding to the concrete wall. You must continue until all of the baseboard moldings are installed. Last, Allow the adhesive to cure for twenty four hours or however long the packaging indicates.
