Spackle is used to fill small holes in plaster walls. It is a white paste that dries hard and can be sanded smooth and painted. When you need to patch small holes in your walls, there's no need to purchase spackle. You can make your own with simple ingredients you already have around your kitchen.

Spackle is used to fill small holes in walls before painting.

Step 1

Mix 2 tbsp. of table salt and 2 tbsp. of cornstarch in a small bowl.

Step 2

Add 5 tbsp. of cold tap water, a tablespoon at a time. Stir as you add the water until the mixture is a thick paste. If the mixture is runny, add 1 tsp. of salt and 1 tsp. of cornstarch and stir until the mixture has thickened.

Step 3

Use the paste to fill small holes in a wall. Apply it to the holes with a putty knife. Use the knife to smooth the homemade spackle so it is level with the wall. Allow the spackle to dry for one hour.

Step 4

Sand the spackled area lightly with 100-grit sandpaper.

Step 5

Paint the wall if desired, including the area that has been spackled.
