Different Painting Procedures for Different Paints

Plan your work so that you always complete an entire wall in one session. If you leave a half-finished wall overnight, or even break off for a meal, the line where you picked up the work will show through the finished surface.

Using gloss or semi-gloss paint

1. The wall will be covered in sections about 500 mm (2 ft) square. Do not make them much bigger, or the paint will start to dry before you have a chance to brush it out. Start at the top right-hand corner (top left if you are left-handed) and cover the first square with vertical strokes.

2. Without reloading, brush over the section with horizontal strokes.

3. Still without reloading, brush over the surface again, both up-and-down and sideways, until the brush glides smoothly over the surface, indicating that the paint film is perfectly even. Reduce pressure as you brush out in this way, so that the brush marks will gradually be smoothed out.

4. Lay off the paint with vertical strokes.

5. Continue working in 500 x 500 mm sections, until the surface is covered.

Take care not to apply a double coat at joins between sections. Work towards the join, allowing the brush to leave the surface gradually, so that the join will not show.

6. Do not brush undercoat and topcoat in opposite directions, otherwise you will produce a ‘cross-hatched’ effect.

Using emulsion

1. Apply emulsion in bands of paint, about 200 mm (8 in) wide, across the wall. Start at the top and work down.

2. Brush out in the same way as for gloss paint. Lay off upwards, in a criss-cross pattern.

Using jelly paint

Thixotropic paints are designed to go on in one coat, and it is essential not to pull them out too far by over-brushing. Apply a full coat and brush it sparingly.
