Professional Drywall Repair Tips
Drywall professionals use techniques to avoid problems with the finished product. Some of those issues can include lumpy mud, popping nails, and bubbles in the tape. This is the process used before you tape the wall. If this is not done, your taping job will not have a good finish.

Steps for Repair
Step 1: Check to locate any nails or screws are in the drywall. Be sure to check closely in corners. Use a screwdriver to screw into the wall securely in case it is attached to a board.
Step 2: Carefully tap all nail heads with a hammer. It should just make a slight impression in the drywall.
Step 3: Use a utility knife to remove any torn or loose paper on the wall where the core may be crushed. If this step is missed, you could have bubbles in the wall later.
Step 4: Apply a stain-blocking primer coat to torn and rough areas. This will ensure that none of the wall stains will bleed through when the wall is painted. Use a vapor-absorbing mask and use good ventilation in the room.
Step 5: Nail a metal corner bead to each corner. Be sure to leave a gap along each flange to serve as a pocket for the drywall compound. You should use a single bead length for each corner, or you will have a crease where the two pieces join.
Step 6: Fill deep gaps with a fast acting setting compound. You don't want to use the regular compound for this step. You want it to harden quickly and not shrink. You can begin the taping process as soon as it becomes hard.
Step 7: Use the powdered mix and add water, but use the type that doesn't set quickly because it will get hard while in the pan.
Step 8: Use the compound (setting-type) to areas that require a deep fill similar to the first coat over the corner bead. Let it get hard. You will then apply a second coat of regular drywall compound.
Step 9: Use the taping knife to shave any bulges left in the setting compound. Do this when it has a bar soap consistency. Don't wait until it hardens, as the setting compound will be hard to sand at that point.
Step 10: Turn off electrical power to outlets. Pull out the switches and fill around the box. Be sure the electricity is off because the knife could hit a hot wire during this process.
Step 11: Clean the utensils before the mud hardens.
Step 12: Sand the surface
