FAQs : Exteriors

When re-decorating my external window frames just before Christmas, I found the undercoat took an unusually long time to dry. Why?

We don't advise carrying out external work at that time of year as drying times will be significantly longer in cold or damp conditions. Dulux Trade Weathershield Exterior Flexible Undercoat is recoatable within two to four hours and whats more contains patented ICI technology allowing the paint to move with the wood to resist cracking or flaking of subsequent topcoat. Use with Weathershield Exterior High Gloss to offer up to 8 years protection.
