Our Drywall walls have become a concern; although you try to ignore them, sooner or later, you will have to deal with damaged walls and ceilings. The interior of most homes is covered with plasterboard, commonly known as Drywall.
Regardless of what it’s called, Drywall is easily damaged over months and years. And these problems, not surprisingly, are aggravated in homes with mischievous and unruly children and pets.
Holes, cracks, dents, and peeling joint tape are unavoidable and unsightly problems with Drywall and must be repaired before a new coat of paint can be applied.
Here we’ll present detailed DIY instructions for fixing the most common drywall problems—from damaged doorknobs to cracks under windows to sagging ceilings.
Most building supply stores sell 2-square-foot pieces of Drywall, which are convenient for minor repairs.
Also, Drywall is cumbersome to lift and carry. To avoid straining your back, always work with a helper and lift your knees, not your back.
How to repair the most common damage to Drywall?
1.Doorknob Strikes: One of the most common drywall accidents occurs when a door is pushed open with too much force, and the doorknob pokes a hole in the Drywall.
The easiest way to fix the hole is with a peel-and-stick repair patch. The patch consists of an adhesive-backed aluminum screen reinforced by a fiberglass mesh. Just peel off the protective foil and press the patch over the hole.

2.Corner repair
Start using a hacksaw to cut the corner bead about 2 inches above and below the damaged section.
Next, take a utility knife and cut along each vertical edge of the corner trim, making sure to cut through the paint and joint compound.

3.Drywall Crack Repair
To repair cracks, start using a sanding sponge to smooth the damage. After sanding, vacuum the attempt to remove all loose dust and debris.
Next, use a narrow putty knife to apply a thin layer of joint compound to the crack. Wait for it to dry and sand. Repeat the operation by applying a second thin layer.
To prevent the crack from reappearing, spray the repair with a thin layer of elastic crack filler.
