How to Paint a Room

By: Harry Sawyers

Shopping List

Supplies You Will Need

1. Paint
A gallon of paint covers about 400 square feet. To figure how much you need, add up the lengths of all your walls, then multiply that sum by the room's height. Subtract 20 square feet for each door and 15 for each window. Divide the result by 400 to get the number of gallons you'll need for one coat. Most walls will need two coats.

For the trim in most rooms, one or two quarts should suffice. If your room has a lot of molding, you may need more. If you think you'll need more than two quarts, it is almost always more cost-effective to buy a gallon.

2. 120-Grit silicon-carbide sandpaper
Get about a dozen sheets and cut them to fit the pole sander or fold them for hand sanding.

3. Sanding sponges
Get three coarse-grit and three fine-grit sponges.

4. Large cleaning sponge

5. latex painter's caulk
Get one tube per room.

6. Patching compound
To fill holes.

7. Primer
One quart will cover patches, but you'll need more to prime entire walls.

8. Painter's tape or blue tape
for protecting hardware and trim.

9. Bucket and tray liners

10. Roller covers
Use a shorter nap 3/8 inch) for latex paint on smooth walls; a longer nap (½-inch and up) is best for rougher surfaces.

4. Cut in around edges

Dip a 2½-inch angled brush into a bucket of paint, loading the paint only a third of the way up the bristles. Tap off—don't wipe—the excess on the side of the bucket. Use the brush to cut in a 2 to 3-inch band of paint at all corners, against the ceiling, and next to molding; this will give the roller some breathing room so it doesn't bump against adjacent areas.
