Step 4 · Install Molding Sections

Apply a bead of strong adhesive specifically designed for molding along the back of each cut piece. For added security, especially on stair walls where vibration might be a factor, use brad nails to secure the molding to the wall studs. Position the first piece of molding according to your layout plan and press firmly into place. Use a level to ensure it's straight. Drive brad nails through the molding into the wall studs at strategic points, ensuring they are countersunk slightly below the surface. Continue installing each piece, aligning the mitered corners precisely. Use a stud finder to locate studs for optimal nail placement.
