Spackling paste is a special kind of gooey material that you can use to fix up little holes or dents in walls or ceilings. You know how sometimes you might bump into a wall or a piece of furniture might accidentally scratch it? Well, that can make little holes or dents in the wall. If you want to make it look like it never happened, you can use spackling paste to fill in those little holes or dents.
Here's how it works! Let's say you have a little hole in the wall. First, you take a tiny bit of spackling paste on a special tool called a putty knife. Then, you use the putty knife to carefully push the paste into the hole. This is called "spackling" the hole. You want to make sure you push the paste all the way into the hole so it fills up the whole space. Once you've spackled the hole, you let it dry for a bit. When it's completely dry, it will be hard like the rest of the wall!
Then, if there are any bumps or lumps of paste sticking out, you can use the putty knife again to gently scrape away the excess. Once you've done that, you can paint over the spackled area just like you would the rest of the wall. And voila! Your wall looks as good as new!
