Step 1
Pick up paint color samples from your local home improvement store that coordinate with the existing furnishings and décor of your two areas, such as the wood of the dining table, curtains, the color of your sofa, and the colors of area rugs or carpets between the two spaces.
Step 2
Select three coordinating colors from your samples. With an L-shaped room layout, the two walls on opposite ends of the L “belong” to the living space of that end of the room, while the other four walls of the L’s body are “shared” between the living room and dining room. Choose one color for the end wall of the dining room, another for the end of the living room, and a third color that will be used along the four shared walls.
Step 3
Push any furniture away from the walls and drape with drop cloths. Use painter’s tape around the entire L-shaped room to mark off the edges of the walls along the trim, door frames and window frames, as well as any other immovable items, such as vents or outlets.
Step 4
Paint the end walls each with their own distinctive color, using a paintbrush near the taped areas for control and a paint roller for the larger areas of wall to be covered. Work the roller in a W shape as you apply the paint for more even coverage over the walls. Allow the first coat of paint to dry before applying a second coat. Let the paint dry.
Step 5
Paint the four shared walls, working with one wall at a time. By the time you finish the fourth shared wall, the first wall may be dry; paint each wall again with a second coat. Allow the paint to dry thoroughly before removing the tape and replacing the furniture in the room.
