Measure the required length for the new skirt board replacement piece. Hook the tape measure onto the existing drip cap and extend it to the previously cut line on the skirt board. Note the measurement (e.g., 53 and 7/8 inches). Transfer this measurement to the new pine trim board. Mark the cut point with a 'crow's foot' V, which allows for a more precise cut, indicating the exact point to cut through. Cut the new skirt board to this precise length.
Goal: Prepare the new skirt board piece to the correct dimensions
This project provides detailed instructions on how to repair damaged exterior trim, specifically focusing on a rotted skirt board and a section of the corner board. The repair involves cutting out the compromised sections, preparing new treated wood replacements, sealing exposed end grain, back priming the new pieces for enhanced weather resistance, and then installing, caulking, and painting the new trim for a seamless and durable finish.
Measure the length of the wall where each skirt board will be installed. Account for any angles at the top or bottom of the stairs. Use a tape measure for accuracy. Transfer these measurements to your new skirt board material and mark your cut lines. Use a miter saw or a hand saw to make precise cuts. For angled cuts at the base or top of the stairs, use a miter saw or protractor to set the correct angle.
This project involves removing old stair skirt boards and trim, preparing the wall and stairs, and installing new skirt boards and trim for a refreshed look. It includes measuring, cutting, fitting, fastening, and finishing the new trim pieces.
