Step 1 · Measure and Mark Molding for Cuts

Begin by measuring the length of each stair nosing where you intend to install the cove molding. Use a measuring tape for accuracy. Once you have the measurements, transfer them to the cove molding. Mark the exact cut points on the molding with a pencil. For angled cuts (often needed at the ends of nosings or where the molding turns a corner), use a speed square or miter box to ensure the correct angle is marked.
