1. If you are right-handed, begin at the top right-hand corner (or the top left it you are left-handed). Spray towards a natural break such as a down pipe.

2. As soon as you’ve completed one band of paint you can begin work on the next. Here, the two windows neatly define the next area to be tackled.

3. Keep the gun at right angles to the wall surface when you are spraying. Spray over the edges of the masked-off areas; the paper will protect them.

4. Before you reach the end of the wall, make sure that you have covered up any adjacent areas which you don’t want to be splotched with paint.

5. Remove the masking tape before the paint dries. Otherwise it would be more difficult to remove and you also risk peeling off the paint.

6. If your masking-oft has been effective there should only be small areas left for you to fill in by hand. A small brush is best for cutting-in work.
