I'm in the middle of decorating a new kitchen/dining room extension. I've painted the newly plastered walls with white Dulux trade supermatt. I was going to paint another colour on top but I've decided I like the whiteness. However the supermatt is not very hard wearing and its already scuffed in a few places and I imagine that the walls are not going to survive much wiping down. Can anyone recommend a paint I could use that will look similar - I don't want anything with a shine to it.
