How to Paint Walls, Ceilings, and Tight Spots

Since the walls and ceilings are the largest surfaces in a room, you'll devote a lot of energy to painting them. In this section, we'll tell you the best techniques for painting walls and ceilings, as well as the tight spots in between.


Walls

Paint an entire wall before taking a break so the painted portions won't lose their wet edges. Then stand back, scan the wall, and cover any missed spots or smears. Whether you paint in sections from top to bottom or from side to side across the room is up to you. But if you're using an extension handle on your roller, you may find it more convenient to start at one high corner and go all the way across the room with a series of completed zigzag patterns. This way you won't have to constantly change the handle on your roller as you would if you painted in sections from the ceiling down to the floor. If you're right-handed, start in the room's left-hand corner; if you're left-handed, start in the room's right-hand corner.

Use a brush to paint along the edge of the ceiling next to moldings and to paint next to corners.

Ceilings

When rolling paint on a ceiling, maintain a wet edge at all times to avoid creating lines and ridges. If you're using fast-drying paint, you may have to work faster than you anticipated and without taking a break. Both speed and ease can be achieved by using an extension handle so you can paint from the floor instead of from a stepladder that has to be moved around the room. Many roller handles are made to accept a screw-in extension that you can buy at the paint store, but you may want to see if the threaded end of your broom or mop handle will work.

When using a roller, work in strips across, always working over the wet edge of previously painted strips.

Tight Spots

You probably won't have enough room to use the zigzag technique described earlier over and under windows and above doors and doorways. Instead, just roll the paint on horizontally. For areas that are narrower than the standard 7- or 9-inch roller, use a 4-inch roller or a paintbrush. (The little roller is best because it will give you the same surface finish as the rest of the wall.) Brushes apply paint less evenly and tend to leave trails.

Now that we've covered the walls and ceilings, it's time to move onto the other parts of a room -- namely the trim, baseboards, wainscoting, windows, and doors.

Should You Paint Woodwork First or Last?
Should you paint woodwork first or last? There is wide disagreement even among veteran painters about whether to paint woodwork before or after painting walls. It comes down to personal preference. The argument for painting woodwork first is that any stray drips or spatters that end up on the wall only need to be feathered out, not removed, since the wall's going to get a new coat of paint anyway. If you get all of the slow, detail work out of the way first you'll feel as if you're flying right along when it's time to fill in the big, flat areas. On the other hand, rollers always emit a powder-fine spray of paint into the room. No matter how careful you are, some of it is going to end up on the woodwork.

Whether you decide to paint the woodwork first or last, be sure to inspect it for defects, and make the necessary repairs before you actually get down to painting. If you'll be painting over already-glossy woodwork, sand it lightly with sandpaper or steel wool first to help with adhesion. Or, give it a coat of deglosser.

Painting trim progresses more slowly than cutting in walls and ceilings, and there's more room for error. Following are some tips for painting the specific types of woodwork.
