Oil based paint is slightly more difficult to apply and must be painted over an undercoat. Use a 75mm brush and work in 300mm square areas. Clean brushes and any spillages with white spirit. It is not advisable to use oil-based paint on large areas like walls or ceilings.
1. Paint three vertical, parallel strips, leaving a space slightly narrower than the brush between them.
2. Blend the strips together by painting horizontally, without reloading the brush with paint. With a nearly dry brush, make light vertical strokes over the painted area to give an even coating. Repeat the process on the area below, working the wet paint into the dry, so the sections marry into each other.
