How do I get clean lines when painting walls?
Repair All SeamsEnsure you have straight lines to begin with by filling in any cracks, gaps or depressions with latex caulk that you can prime and paint, or use drywall compound where walls meet other walls, ceilings or trim.Mask off the Neighboring SurfacesUse painter’s tape where walls abut with other surfaces of a different color or sheen. Apply the tape along the length of the walls, ceilings or trim you want to protect, and burnish it in place with a drywall knife to seal it tightly to the surface. Always remove painter’s tape promptly after paint has dried and prepare to touch up some places where paint sneaks under the tape.Use a Quality BrushCut in with a quality brush, such as a 2.5- or 3-inch angled sash type. Invest in a good paintbrush, and it will last a long time if you take care of it. A brush with good manufacturing provides a nice even and controllable flow, and with some practice you will find you can achieve very straight lines when painting.
