Worsted is a woven fabric named after the Norfolk village where it was originally made. Farrow & Ball\'s own Worsted takes its colour from the suits often made from this material, most often in deep shades of grey. It\'s lighter than Mole\'s Breath, but deeper than Purbeck Stone, and makes a great accompaniment to both.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.
