Scrape out any loose debris from the hole or crack in the textured wall, using a utility knife. Cut away any loose paper, using the knife.
Apply a minimal amount of ready-to-use spackle to cover the entire hole or crack, using your finger, or a putty knife. Scrape away any excess spackle to make the spackle as smooth as necessary and also flush with the wall surface.
Dampen a sponge with water, and dab the sponge into the still-wet spackle to create matching texture in it, or use whatever technique was used to create the texture pattern in the rest of the wall.
Allow the spackle to completely dry, following the product manufacturer's instructions as to the amount of time needed.
Paint over the spackle, using a paintbrush, if the spackle dries to a different color than the rest of the wall.
