You can find a nail set at your local hardware store if you don’t have one. Hold the pointed end of the nail set on the head of the nail. Hammer the nail set so the nail goes into the trim. If the trim is held on with staples, use a flat-head screwdriver approximately the same size as the staples to tap them into the trim. Use a putty knife or painter’s 5-in-1 tool to pry up any staples or nails that are bent into the wood. Then, use needle-nose pliers to remove the staple or nail from the trim. Sometimes nail holes in trim can form a raised edge. It’s important to get rid of these edges on the trim or they’ll show after you fill the holes. Scrape the putty knife across the surface of the nail hole a few times to smooth out the area around the hole.  Be gentle when you’re using the putty knife. You don’t want to cause damage to the trim around the nail holes. If the trim has ridges or raised edges, use a butter knife to remove the fragments so you don’t damage the details. Any sandpaper with a grade between 120 and 220 will work. The sandpaper should be able to get off any raised fragments on the trim that the putty knife couldn’t. Brush the sandpaper across the surface of the nail holes a few times until they feel smooth.
