Dulux Simply Refresh One Coat has been specifically formulated to easily give you the perfect finish in just one coat. Its extra thick formulation (Extra thick compared to Dulux Matt) means you only need one coat to refresh your home in a fraction of the time and with less paint (Less paint needed compared to 2 coats of Dulux Matt). When Pure Brilliant White is used over dark colours, an additional coat may be required to achieve the desired finish.
