In our dining room, we have the chimney breast and two alcoves painted in Farrow and Ball Paean Black estate emulsion. I absolutely love the colour and mattness of it, but it's getting a lot of marks on it on the chimney breast, where it's close to our table. I'm thinking about painting just the front of the chimney breast in the modern emulsion to cover the marks and make it wipeable and hard wearing. Is the finish very different? Would it look very different?
