On all of our external decorations we use Dulux Weathershield paints and woodstains which are in our opinion the best products available. The Dulux Weathershield Exterior Gloss System (WEGS) can provide up to 8 years protection and the Dulux Weathershield AP Woodstain is available in a choice of colours and can provide up to 6 years protection and external decorations carried out using these products are covered by the Dulux Trade Select guarantee.
