Step 1: Painting the edges

Use a 50mm (2in) brush to paint around the ceiling edge and along the top of the skirting boards.
Make a neat edge around any features like fireplaces and window frames.
Dip the brush a third of the way into the paint and use long continuous sweeps of the brush edge to form a neat line.
Tip: Use masking tape to help you make a neat job of the edges.

Step 2: Painting the walls

With a wide brush or roller, fill in the remaining areas. A roller gives the best finish and is quicker.
Work from the top right-hand corner of the first wall and work in square metre sections.
Tip: If you use a brush, apply the paint in up-and-down strokes, then work the paint into the surface with horizontal strokes. Then lightly brush up and down again. If you use a roller, use a short pile for smooth walls and a medium pile for covering textured wallpaper. Evenly cover the roller with paint from the tray and work diagonally in a criss-cross pattern.

Step 3: Painting the ceiling

Start in one corner and paint around the edges of the ceiling - the same way as for the walls.
Brush or roller on the rest of the paint in overlapping strips across the ceiling, parallel to the longest wall.
Tip: Turn off the power supply and unscrew any light fittings before painting around the wires.
