1. Start near the floor
Cut in by applying paint around the edges of the wall. Load a roller with paint and start 300mm from the floor and 150mm from the side, rolling upwards at a slight angle with light pressure. Stop short of the ceiling and roll down, working quickly and overlapping the starting edge.
2. Continue in stages
Reload the roller and repeat from a starting point further across the wall, working back towards the painted area. Turn the roller on its side to get close to the cut-in areas, wiping away excess from the end of the roller first. TIP With good technique, two walls can be covered in an hour.
3. Overlap the strokes
Roll back over the painted area with light pressure to smooth and blend, moving across so the roller slightly overlaps the previous stroke and continue across the wall. Without reloading, smooth the paint along the ceiling and skirting edges using long, horizontal strokes.
