According to bobvila:
Add a little baking soda to a drop of super glue to form a super-strength sealant. After quickly combining these two products with the help of a toothpick, immediately apply the mixture directly to the wall. After it dries, start sanding the hard, plastic-like finish until it’s flush with the wall. Not only is this fix effective for small holes, but it can solve cracks in corner walls too!
If you think it through you will will realize quickly that gloves are highly recommended. (If you do get your fingers glued together nail polish remover will unstick them!)
In a pinch, white toothpaste is also a handy tool for filling holes. It will dry into a caulk-like finish that you can sand down and paint. But the crazy glue and baking soda is definitely the stronger solution.
Do you have a quick way to fill holes or even another hack to do some kind of household repair? Please tell us about it!
Thank you to bobvila for his expertise!
