Painting II
If using a rollerIf using a roller: pour the paint into your roller tray to a depth of about 25 mm (1 in). Run the roller down the slope of the tray and into the paint, then roll it up and down the slope to load the sleeve evenly.
Apply in different directions: Roll the paint on to the wall or ceiling in two or three parallel bands at a time, then work the roller across the area.
Repeat: Finish by rolling in the original direction. Reload the sleeve whenever it begins to run dry. You won't be able to paint right into internal corners with a roller; go as close as you can, then touch in the edge strips with a paintbrush.
If using paint pads: Pour about 12mm (1/2in) of paint into the loading tray. Hold the pad parallel to the surface of the paint and dip it in. Squeeze out the excess paint. Start painting, drawing the pad over the sureface in touching parallel bands.
Blend: Then draw it lightly across the bands to blend them together and finish off with light strokes in the original direction. That is all there is to it. As with rollers, you might need to use a smaller pad or a paintbrush to touch in the edges of the area.
