Learning how to paint a room properly is essential for beginning DIY’ers, new homeowners, and veteran home improvement experts alike. After all, it’s pretty painless, relatively inexpensive, and—should something go horribly wrong—easy to fix. But before you grab your roller and get started with your first coat, it’s essential to have a plan of attack. So we asked a handful of experts for their best painting tips and tricks to get you started. Read on to learn how to paint a room and see step-by-step what you’ll need to do to make sure your project is a success.

1. Plan your approach

Start by thinking about how you want the finished project to look and remember that you’re not limited to four walls or an entire room in the same color. Consider painting an accent wall in a bold hue or highlighting moldings in a contrasting shade or finish. And don’t forget to look up and see whether the ceiling could use a refresh as well.

Alexander Gorlin used Parma Gray by Farrow & Ball on an accent wall in a New York apartment.

2. Choose your color

Browsing through fan decks and paint chips can be overwhelming. Start by figuring out the general color characteristics: Do you want a warm or cool shade? Neutral or saturated? If you have existing furniture or art, you’ll also want to consider how the shade will complement them. Once you have a sense of what you’re looking for, pick a few shades and get samples—lots of direct-to-consumer brands, like Backdrop and Clare , will send you adhesive swatches you can slap on the wall for a better sense of shade (and it’ll save you a trip to the store). Test the colors to see how they look in the room at different times of day.

Many paint companies also have tools on their websites that will let you upload a photo of your space and preview different colors on the walls. But colors can look different in real-world conditions, so you’ll still need to try it out in the space.
