When shopping for new internal doors, you've given the choice of three finishes: unfinished, primed and fully finished.
Primed doors (sometimes referred to as pre-primed) have had a base coat of primer (a protective seal) already applied, meaning all that's left for you to do is lay a few coats of paint on your white doors in your chosen colour, apply a final top coat as a finish, wait for it to dry and hang it.
You can paint your internal door with just one colour or get really creative with patterns, the world is your oyster! Changing the colour of white internal doors door can mean that you have a wider choice of styles and can switch from traditional to modern (or vice versa) with the flick of a paintbrush.
