The two basic techniques for painting both ceilings and walls are cutting in and rolling. “Cutting in” means brushing paint onto areas that can’t be reached with a roller. Painters usually begin working from a ladder, cutting in the corners where the ceilings meet the walls. Use a 3-in. or 4-in. brush to make a cut-in band all around the ceilings and walls, as shown in the photo at left. This band will be overlapped when the large open spaces are painted with a roller. Professional painters prefer to use a brush for cutting in, but it can also be done with a paint pad, which is basically just an absorbent sponge on a handle.
Take your time. Good brushes are easy to load with paint. Rather than painting with a full can of paint, painters like to use a bucket that’s about half full. This allows them to dip the bristles about halfway into the paint, then fill the inner part of the brush with a few gentle slaps of the brush against the inside of the can (see the photo below). Apply paint in relaxed, even, gentle strokes.
Use a roller to fill the field
Once you’ve finished cutting in, switch to a roller to paint the rest of the ceilings and walls. Ask at the paint store which roller to use for your type of paint and wall surface. Many painters use a good-quality 9-in. roller frame fitted with a */2-т. synthetic-nap roller. An extension pole that attaches to the frame makes it easy to reach the ceiling. Paint can be loaded on a roller from either a paint pan or from a 5-gal. bucket with a roller screen hooked to the inside. Don’t overload either the pan or the bucket with paint. Dip the roller into the paint several times to saturate the nap. Then unload the excess paint on the pan or roller screen (see the photo below).
Rolling paint on ceilings and walls must be done slowly and methodically, using long strokes. It must be done slowly because pushing a roller rapidly scatters paint far and wide.
It must be methodical so that every square foot of drywall receives full and equal coverage. Try painting in 3-ft. squares, running the roller back and forth in a tight “M” or “W” formation, with each stroke overlapping the previous one by a few inches. Blend the main ceiling paint into the corners by overlapping the cut-in sections by an inch or so, but be careful not to touch the other side. In hot, dry climates, try to keep the working edge wet with paint. If you overlap a dried edge, you’ll often see a lap mark after the paint has dried.
When rolling paint on walls, you can reduce the splatter by painting on the upstroke. Watch out for paint ridges left at the ends of a roller. Try tipping the roller to the side to squeeze out the excess paint as you roll. Then go back over the ridge and even out the coat. Apply a uniform, thick coat, but not so thick that the paint begins to run. When painting near the floor, turn the bend in the roller frame toward the floor to keep the roller from picking up dust and dirt. With care, you should be able to cover the walls and ceilings with one coat on top of the primer, especially if you’re using good-quality paint. But don’t despair if one coat looks a little
thin. Paint is not all that expensive, so just roll on another coat, if necessary.
