Using your DeWalt DWAS12025P sandpaper is a breeze. First, attach the sandpaper to your sanding tool using the hook - and - loop system. Make sure it's firmly in place before you start. When sanding drywall, move the tool in smooth, even strokes for a consistent finish. If you have a vacuum system, connect the sandpaper to it to keep the dust down. This will also help the sandpaper last longer. As for maintenance, after each use, give the sandpaper a quick shake to remove any loose dust. If it starts to wear out, simply replace it with a new piece from the pack. Keep the sandpaper in a dry place to prevent it from getting damaged. And always remember to wear safety goggles and a dust mask when sanding to protect yourself from dust particles.
