IT'S PREP BEFORE PAINTING
The easiest and cheapest way to renovate a room is to paint it, but hiring a professional can still cost $300 to $400. Homeowners can do the same job themselves for about $150. Sure, there's more to painting than just picking a color and slapping it on the wall. It's best to take a day to prep before you start to paint, for example; you want walls to be in the best possible shape before they see a new color. But with the proper prep work and a few tips, a DIY job can look perfect and last for years.
