Once you’ve decided to do the room painting yourself, do some planning to make sure you’re saving as much money as possible. Gather all the necessary painting supplies, pick a time to start painting, and read up on painting basics—like how to paint a wall—and finer points of the task, such as how to paint corners. Then follow these prep and painting tips to make the project a truly low-cost endeavor. If borrowing isn’t an option, companies such as Backdrop and Clare sell painting essentials kits that can be shipped straight to your door. Buying trusty supplies now can help you save on the next painting project.
