 It is advisable to divide the project into manageable stages, especially if you are working on your own. Start by painting woodwork around the roof, and then move on to guttering, house walls, brick walls, windows, tiled sills, and finally any weatherboarding.
 Surfaces must be prepared at least two weeks before the painting is due to start. Existing paint must be stripped and any repairs to the walls carried out. Also check that gutters and downpipes are secure, and that the putty around windows is sound.
 Divide the walls into sections that can be completed in one painting session, using window frames, doorframes, bays, downpipes and corners of walls as break points to disguise joins.
 You should start painting at the top of the house and, if you are right handed, work from right to left.
 To calculate the quantity of paint needed for the walls you need to first calculate the surface area of the walls: height of the wall x length of the wall. The easiest way to measure the height of the walls is to climb a secured ladder to the highest point on the eaves with a ball of string. Holding the end let the ball of string drop to the ground. On returning to the ground measure the length of the string. The area that 1 litre of paint will cover should be on the paint tin label. Remember that rough walls will need more paint than smooth ones.
 To calculate the paint required for pipes and gutters, calculate the surface area in square metres by using this formula:
length (centimetres) x circumference (centimetres)
10,000
