Tools you will need:
paint brush, emulsion paint, paint roller and roller tray, stick or spoon, paint pads, pad-rolling tray
The paint
Dust the top of the paint container, then prise off the lid. Stir the paint if there is any clear liquid on the surface, and leave it to stand for an hour if it is a non-drip type so that it can turn back into a jelly.
Access equipment
Then set up your access equipment. If you are painting a whole room, do the ceiling first.
If using a brush: dip it into the paint to about half the bristle depth and scrape off any excess by wiping it against the inside edge of the container.
Apply evenly
Brush the paint on in parallel strips first; then brush across the strips in the same direction to blend them together. Finish off with light brush strokes in the original direction.
Repeat
Reload the brush and repeat the process, completing a strip of wall or ceiling about 300 mm (12 in) wide at a time before starting the next strip.
Be sytematic
On walls, start in the top right-hand corner if you are right-handed, and the left-hand corner if you are left-handed. On ceilings, start above the main window.
