The Accubrush Paint Edger Tool
Cutting in at the ceiling in particular can be tough to do, particularly where there is a great color difference. Dark walls up against a white ceiling will show every wiggle in the line if done poorly with a free hand / brush method. Even painters have to really slow down and get it right when there is a dramatic color difference.
You can actually paint cut in lines as well as a professional, at the ceiling / wall corner with this tool - and do it faster! You don't have to go up the ladder for most of the cut in (you do in the corner itself), for standard height ceilings.
The roller holds a LOT more paint than a paint pad, making this tool much faster than a standard paint pad edger.
You will not run into the problem known as "picture framing" with the Accubrush, where the cut in paint done with a brush or pad edger, looks different than the paint applied with a roller. With the Accubrush, the brushed paint is kept very small, minimizing any noticeable framing.
Taping is not always an option on very fresh paint. The best light tack, easy removal tapes can cost a lot of money to mask off an entire room. You must be careful to burnish down the tape well or you may after all your trouble, still get some paint bleed under the tape.
*Picture framing is most noticeable when painting with dark colors
