Any user of drywall is bound at some point to face the challenge of a hole. The light nature of drywall. The ugly look it leaves behind makes it necessary to plan for repairs.
Here are the steps on how to proceed with the repair work if you choose to do it yourself.
- Get all the necessary tools needed from your drywall supplier. This includes a 4 inch drywall knife along with the usual 10" one. You will also need the drywall compound.
- Cut out a square shape area around the hole with clean edges.
- Get two plywood strips that are about 4" longer than the hole and place them inside the whole fastening them with drywall screws on their extended surface.
- Cut a patch piece of drywall of matching size with the hole area and attach the piece securely on the plywood ensuring the sides are flush all round the previous drywall.
- Using the 4" knife place a thin coat of drywall compound extending the coat beyond the edges of the hole.
- When dry knock off any ridges with the 10" knife to level the surface. Then apply another coat as in step 5 this time going an inch further than the first coat.
- Wet down the 10" knife and draw off most the compound by moving it across the surface. Once dry repeat steps 6 and 7.
- After a couple of thin coats and scrapping, place the final coat that overlaps the edge of the area. Draw out the compound with the 10" wet knife. This should be the last coat unless you are placing thinner coats for touch up making all edges even.
- Ensure you have drawn off most of the compound and scrapped off the bumps and ridges with either knife. The 4" knife allows for more pressure to be applied especially when held by two hands so you can use it for the finishing. Still do not sand at this point.
- Shine on the area with a trouble light or lamp at a low angle. Identify any scratches and depressions and fill them with well thinned small amounts of drywall compound. Scrap off much of the application for a smooth finish.
- After enough scrapping and the surface is rid off any bumps, you can now sand the area. Use a 220 grit sand paper and lightly sand for a smoother finish. There should be no trace of the damage.
- You can now prime your wall with latex primer and paint to match the surrounding wall.
For a better result, you should do a whole repainting and repriming job for that entire section at least up to a door or joint. It is also important that you get quality drywall supplies.
This ensures you have a good compound mix easy to thin and apply. You supplier should also get you a latex primer matching your drywall. The quality of materials also determines the kind of finish you get.
