20. Refresh stairs with paint:
If your house has wooden stairs, they often wear down over time. So why not take some time to give it a fresh coat of paint? You can also use paint sprayers to make the process easier. Meanwhile, don't forget to cover any place that you don't want to change. You can use tape or newspaper for this. Make sure to wear a breathing mask as you'll be painting indoors. Finally, you can upgrade the color by hand. However, you should use a large bristled brush to finish it.
