About the full video
This DIY project details the process of installing farmhouse-style interior window trim, also known as Craftsman-style, using common lumber dimensions like 1x4s, 1x6s, and 1x2s. The instructions cover the complete installation of the bottom, side, and top trim pieces, including specific measurements for overhangs, followed by finishing steps such as priming, applying wood filler, sanding, caulking, and painting to achieve a clean, professional look.
Step 8 of 10: Fill Nail Holes
Using a small putty knife, apply a small amount of wood filler or spackle to each nail hole. Overfill slightly to account for shrinkage. Smooth the filler flush with the surface of the trim. Allow the filler to dry completely according to the product manufacturer's instructions.

Questions about Stair Skirt Boards and Trim Refresher
Is this project truly beginner-friendly, and can it really be done in 3 days?
While listed as beginner, this project requires patience and precision, especially with measuring and angled cuts. A 3-day estimate is feasible if you dedicate full days to the work, but expect it to take longer if you're new to these techniques or have limited time each day. Proper preparation and dry fitting are key to saving time and frustration.
What are the most essential tools I'll need for this project, beyond basic hand tools?
A molding pry bar and nail puller are crucial for safely removing old trim without damaging the wall. A miter saw is highly recommended for accurate angled cuts on the new skirt boards and trim, especially for staircase stringers. Don't forget a reliable tape measure and a caulk gun for construction adhesives.
Why would I choose PVC trim boards over traditional wood for stair skirt boards and trim?
PVC trim boards, like the suggested Veranda PVC, offer excellent moisture resistance and durability, making them less prone to warping or rotting than wood. They are also easier to clean and don't require sealing before painting. However, they can be more expensive and require specific fasteners or adhesives in some cases.
What are common mistakes to avoid when measuring and cutting the new skirt boards for stair angles?
The most common mistake is inaccurate angle measurement, leading to gaps. Use an angle finder or create templates from cardboard for precise cuts, especially where the skirt board meets the stair treads and risers. Always measure twice and cut once, making test cuts on scrap material if unsure.
When should I use construction adhesive versus finish nails for installing the new skirt boards and trim?
Construction adhesive (like Titebond) provides a strong, long-lasting bond and helps secure pieces tightly to the wall, reducing future movement. Finish nails are used to hold the pieces in place while the adhesive cures and provide additional structural support. For trim, nails might be sufficient, but for skirt boards, a combination is best for durability.
How do I handle small gaps between the newly installed skirt board or trim and the wall/stairs?
For small gaps, use paintable caulk to fill them before priming and painting. Ensure the caulk is applied neatly and wiped smooth for a seamless finish. For larger gaps, wood filler (like Varathane) or a small strip of trim might be necessary, followed by sanding and caulking.
What safety precautions should I take, especially when removing old skirt boards and trim?
Always wear safety glasses to protect your eyes from flying debris or nails. Use gloves to prevent splinters and cuts. Be mindful of hidden electrical wires or plumbing behind old trim, and avoid excessive force during removal to prevent wall damage. Ensure the area is well-lit and clear of tripping hazards.
