Dulux Trade White Undercoat

Product Overview Dulux Trade White Undercoat is a high-performance, solvent-based undercoat engineered for professional brush and roller application on interior and exterior wood and metal surfaces. Designed to build a smooth, high-opacity foundation, it optimizes intercoat adhesion and maximizes color depth and gloss retention when overcoated with finishes like Dulux Trade High Gloss. Superior Opacity & Flow: High pigment concentration ensures maximum obliteration over dark or uneven substrates. Versatile Application: Suitable for correctly prepared interior trim, doors, window frames, cladding, and metalwork. Edge Retention: Formulated to maintain film build and grip on sharp edges and detailed moldings.
