The Crown Trade Full Undercoat Dark Grey 1L is a professional-grade, solvent-based traditional undercoat engineered to provide a solid, high-opacity foundation for interior and exterior timber and correctly prepared metalwork. Widely specified by professional decorators and contractors, it is specifically tinted to dark grey to serve as the ideal base layer under strong, dark topcoat colors like dark blues, deep greens, blacks, and charcoal gloss or satin finishes.
 
Formulated with premium alkyd resins, this undercoat offers exceptional obliteration and surface-filling properties, ensuring dark topcoats achieve full color saturation in fewer coats. It delivers outstanding adhesion to bare wood, primed metal, and existing sound paintwork, forming a dense, uniform film that maximizes the final finish's color depth, gloss retention, and overall durability.
 
Supplied in a compact 1-liter tin, it provides excellent coverage and convenience for small-scale projects, doors, detail trim work, and targeted touch-ups. The solvent-borne formula delivers smooth flow and leveling for a brush-mark-free finish, excellent sag resistance on vertical surfaces, and robust film strength designed to withstand demanding interior and exterior environments.
