Farrow & Ball Dead Flat paint is their new finish which can be used across walls, metal and woodwork to create what they describe as a 'washable wipeable scuff resistant' matt finish.
I have 120sqm (actually 60sqm area wise if you paint 2 coats) of a warm neutral sandy/parchment colour called String. It would normally cost £270. I have:
1 x 5L tin 60sqm
1 x 2.5L unopened still in box 30sqm
1 x 2.5L tin 30sqm with a little missing due to spillage after the box was damaged in transit - which is why the tins in the picture look a bit battered.
