For use on exterior woodwork, the Farrow & Ball Exterior Wood Primer & Undercoat provides a protective, flexible and breathable foundation when using either Exterior Eggshell or Full Gloss. For the best possible finish, it is important to pick the right shade for your chosen topcoat.
Using a Primer & Undercoat seals the surface you’re painting on. You should have a full, solid coat of Primer & Undercoat before applying your topcoat, to ensure that your chosen Farrow & Ball finish sticks to it fully, is evenly absorbed, and has a smooth and even finish with rich depth of colour.
