Ash Grey is from the Colour by Nature palette, created in collaboration between Farrow & Ball and the Natural History Museum. It\'s a laid-back shade of grey with a definite green undertone. While relaxed enough to be used in all kinds of rooms, it\'s an intriguingly changeable shade, appearing more intensely green in bright natural daylight and more grey in darker areas.Exterior Eggshell brings long-lasting colour to outdoor spaces with a finish that remains flexible once dry, protecting wood and metal surfaces through changing weather. Added preservatives help to prevent the growth of algae and fungi, and the resin-rich formula resists flaking, peeling, and fading for up to six years. Providing it has been applied in accordance with Farrow & Ball Product Advice Sheets. Not suitable for use on exterior plastic surfaces or decking.
