Painting a wall – step by step

1. Choose your paint

Before you start choose the paint colour and determine the best finish for the look you want. Matt is contemporary and will conceal flaws. A mild sheen is best for light colours as it captures subtle shades within the colour, especially neutrals. A silk finish will bring out the depth of the shade and will achieve a liquid when used with a dark colour.

2. Prepare the room

Cover and move all your furniture and soft furnishings. Cover the floors with dust sheets or newspaper. Protect your woodwork and ceilings by taping along the edges using masking or Frog tape. Next mask off skirting boards and coving with decorator's or Frog tape.

3. Repair damaged walls

To ensure a smooth finish, sand the surface that you are going to paint.

Fill in any cracks or holes using filler and a flat scraper. Allow the filler to dry, the time will be determined by the instructions on the packaging (approximately 24 hours). Then re-sand those areas once set, to ensure the wall is completely even and smooth.

5. Clean and dry the surface

Wash all surfaces with a sugar soap solution, rinse thoroughly and dry. If your walls are in good condition and you are not going for a dramatic colour change there is no need to prime, however, it is recommended to achieve a professional-looking result.

6. Cut in with a paint brush

Once the primer has dried (approximately 2-4 hours) it's time to start painting. Cut in about 1 to 2 inches with a paintbrush to achieve clean lines at the edges and corners.

7. Switch to the roller

Then use a roller to paint the larger areas. Start with a large 'V' shape and fill in the areas with a roller.

Paint the whole wall with this method and leave to dry for again approximately 2- 4 hours.

8. Add a second coat
