Step 1 Fill the Hole with Spackle
The simplest way to permanently fix a hole in drywall is to purchase a quality joint compound filler or putty. Spackling paste, or spackle, is a type of putty used to fill small holes, cracks and other defects in the surface of drywall, wood, and plaster. Spackle is inexpensive, dries quickly and doesn’t leave behind noxious or dangerous odours, making repairs quick and easy to do.
Inspect the hole to determine how much spackle you’ll need to apply. Use fine-grit sandpaper to smooth out any uneven/rough areas around the hole in your drywall. Then, using the putty knife, apply the spackle to each hole. Scrape the spackle gently over the hole at a 90-degree angle for a more even application.
To make your drywall repairs easier, use 2 putty knives with differing widths. The wide putty knife can be used to fill the hole, while the narrow putty knife can be used to scrape and trim away excess spackle more accurately. A damp cloth is also very useful for removing the excess without damaging your drywall.
To repair large holes more than 2” inches in diameter, you may need to use a wall repair patch before applying spackle.
Tip: When repairing drywall, remember to keep the lid on your spackle jar closed when not in use. The spackle dries quickly once exposed to air, making it increasingly hard and difficult to manipulate.
