Dip your putty knife or a moistened finger into the jar of spackling paste and scoop out a small amount, about the size of a tablespoon.
Apply the spackling paste across the drill hole, pushing it in and around the hole. Apply enough so that you no longer see the hole but do not overfill it. A little spackling paste goes a long way.
Scrape off the excess spackling paste using the edge of the putty knife so that the paste is smooth and flush with the wall.
Allow the spackling paste to dry for the time recommended by the manufacturer. Small amounts of spackling paste generally dry in less than 30 minutes.
Sand the area until smooth. Sometimes the spackling paste will dimple a little after it dries. If so, simply repeat the process from Step 1.
