This guide is for DIYers and professional decorators looking for a durable, weather-resistant paint solution for exterior woodwork. The Dulux Trade Weathershield Exterior Flexible Undercoat offers long-lasting protection and excellent flexibility, flexing with the wood to prevent cracking. A key caveat is its solvent-based nature, requiring specific preparation and application methods, and it's part of a three-part system for optimal results.
