Dulux Trade Weathershield Exterior Preserver Primer Plus

This exterior preserver primer is intended for preparing and treating outdoor timber before painting. It is used on bare or previously untreated exterior wood, including window frames, doors, fascias, and soffits, providing a suitable base for topcoat applications.

On site, the 1 litre size is practical for smaller projects or targeted repairs and is usually applied by brush. The primer helps ensure an even surface that supports good paint adhesion, making it a suitable choice for both new installations and maintenance tasks on existing timber.
