You can make scratches nuts. No matter how hard you try, you can’t cover them up. You have to sand the door to remove the scratch while you are preparing a home for resale or just want to set a door in your own home. It isn’t that big: you need a hand sand block and a little bit of cotton grate, and you can sand the door in about two hours.
1. Remove the door from the jamb and position it flat in a well-ventilated area over two sprinklers. Using 100-scrap sandpaper in one corner on a hand block and then begin to sand four inches forward and then three inches backward. Sand often parallel just to the grain. Continue with a normal pattern until you hit the other end of the door and begin again and then half-inch overlap the first pattern.
2. When the lacquer jams up, or every 10 minutes, refill the paper powder.
3. When you get to it, emphasis on the scratch. Sand on the scrape back and forth until it vanishes and you just see bare wood. Keep sanding the door until it is removed from the lacquer. Wipe the entire dust out of the door surface to test it. Sit down so that the surface reflects light. You can see bright patches if the lacquer stays at the entrance. Shake it until they vanish.
4. Wipe the door with cotton cloth with the required stain. Save this move if the door is normal. Wait for 30 minutes to dry the stain, then spray a lacquer coat on the frame. Hold the door at a 30-grading angle for eight inches and scatter parallel lacquer bands at the door. Wait 15 minutes, then put pliable 180-grit sandpaper in the door. Finish with a single lacquer coat by spraying the frame.
