Step 2 Peel off the nonstick paper at the back of the patch. Press the patch on the wall firmly. And please make sure the aluminum sheet completely covers the hole.
|
Step 3 Apply putty evenly to completely cover the patch. Then wait until the wall is dry.

Step 4 Sanding the drywall again and painting the wall with the same color paint. Then you will get a brand new wall.
