With all of your molding ready to go, you can start nailing it into place using the pneumatic nail gun. Nail at the center line of the molding, to help prevent cracks. How far apart the nails are depends on how secure you want it to be but roughly every 1–2 feet (0.3–0.6 m) should do it. Make sure that your nails are going straight into the baseboards and not angled down into what is probably a gap or floorboards. To do this, you'll probably have to have the nail gun on the floor. If you have a nail setter, setting the nails will allow you to get a more professional appearance. Place the nail setter against the nails and tap it with a block or your hand to counter-sink the nails. You need to decide how you want the end to look since it will often stick out from the rest of the molding. There are a few options:  Consider a mitered return. This is the most common method of creating a return and probably the easiest. Miter cut the end of your last piece of molding and then carefully miter cut a tiny single piece. Place them together so that the molding turns back into the wall, creating a much cleaner look. Consider a bull-nose return. A bull-nose return is another option, although it requires more tools. Essentially, cut the molding to the length you want it to reach and then use the coping saw and sandpaper to round the end down until it looks nice on its own. Consider a wrap around with no return. Under some circumstances, it may be possible to skip returns by having the molding wrap around a doorway and continue on into the next room. This is not ideal for all homes, however, so only do this is it makes sense and looks nice.
