Professional trade formulation
Using a dark grey undercoat beneath deep or bold finishing colours helps achieve stronger colour saturation and reduces the number of finishing coats required. It provides a balanced base that improves uniformity when applying darker gloss or satin paints.
This makes it particularly useful when switching from light to dark colour schemes.
Recommended for use on:
Interior and exterior timber
Doors, frames and trim
Skirting boards and joinery
Window frames
Primed metal surfaces
For bare wood or metal, apply an appropriate Dulux Trade primer before undercoating.
Ensure surfaces are clean, dry and properly prepared before application. Stir thoroughly and apply evenly with a quality brush or roller. Allow sufficient drying time before applying the chosen dark gloss or satin topcoat.
For projects requiring rich, deep finishing colours, this 2.5L dark grey undercoat provides the ideal foundation. Its strong covering power and smooth application help deliver professional, long-lasting decorative results across interior and exterior surfaces.
