Using the DeWalt DWAS24025P sandpaper is easy. First, attach the sandpaper to your tool using the hook - and - loop system. Make sure it's firmly in place. When sanding drywall, move the tool gently across the surface. This will let the open - coat design do its job and smooth the drywall quickly. If you have a vacuum system, connect the sandpaper and the suction holes will help reduce dust. As for maintenance, keep the sandpaper in a dry place. If it gets clogged with dust, you can gently tap it to remove the debris. And if it starts to tear or wear out, it's time to replace it with a new piece. Just remember, always wear safety goggles and a dust mask when sanding to protect yourself from dust and debris.
