Before you start

How to paint a wooden window frame

Have a think about what colour to paint your windows. A coat of white paint will have a brightening effect and won't compete with a feature wall.

However, to make a statement, choose shade of colour that's a few shades lighter or darker than your walls. This will help your windows become more of a focal point within your room.

More of a chameleon? Paint your window the same colour as your walls. To find an exact match try our Valspar colour mixing service.

Top tip

Cover your furniture and flooring with dust sheets the night before you start your painting project. That way you can get stuck in straight away the next morning.
