1

Trim the loose paper

Use the utility knife to cut away any torn drywall paper around the hole — you want a clean edge.
2

Stick the patch

Center the mesh patch over the hole and press the adhesive border firmly against the wall.
3

First coat: cover and smooth

Apply joint compound over the patch with the taping knife, pressing it into the mesh. Skim a thin coat extending 2–3" past the patch edges. Don't worry about perfect.

Tip: Joint compound shrinks as it dries — three thin coats look better than one thick one.
4

Second + third coats (the next day)

After fully dry, sand lightly. Apply a wider second coat (6" past the patch). Dry, sand. Final feathered coat.
5

Prime and paint

Spot-prime the patched area to prevent flashing, then paint with your wall color.
