HOW TO PAINT A CEILING
You can paint a ceiling working from a stepladder or a work platform (make sure yours is stable) or from the floor using a roller or paint pad with a handle extension. If you are standing on a platform, leave at least 3 in (7.5 cm) above your head, Divide the ceiling into sections of about 1-1/2ft (30-45 cm) wide and work each section away from the main light source.

USING MASKING TAPE
If you intend to divide an area horizontally into two colors or to paint around an object such as a switchplate, it is helpful to stick down low-tack masking tape to create a straight line between the different color divisions. You can use tape along the edge of the floor to keep it free of paint when you decorate the baseboards. Also use masking tape to attach stencils to a wall.
1. Mark the line between the two colors with a soft pencil and a ruler. Check the alignment of the horizontal line with a level and the vertical line with a level or plumb line.
2. Stick down the masking tape along the line, making sure that the pencil line is still visible. If your dividing line is vertical, stick the masking tape along the far edge of the line.
3. Apply paint from the middle of the masking tape downward with a small decorating brush. Once you have covered the immediate area, paint the rest of the surface with a large brush.
4. When you have finished painting the wall and the paint is completely dry, you can pull off the tape. The use of low tack masking tape keeps the paint from being peeled off at the same time.
