Cutting gypsum board (drywall) is a straightforward process that requires minimal tools. First, measure and mark the dimensions you need for the cut. Use a utility knife or drywall saw for smaller cuts. For a clean, straight edge, score the board along your marked line with the utility knife. Apply firm, even pressure to create a deep score along the surface. Then, snap the board along the scored line, folding it over gently. To cut through the backing paper, use the knife to slice along the other side. For more complex cuts or around fixtures, a drywall saw works well to cut curves and tight angles. When cutting large sheets, it's helpful to have an assistant to hold the board steady. Always wear safety gear, including gloves and eye protection, to avoid injury while cutting.
