The Crown Trade Full Undercoat White 2.5L 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, contractors, and maintenance teams, it is designed for use beneath solvent-based topcoats such as traditional full gloss or satin finishes.
 
Formulated with premium alkyd resins, this undercoat offers exceptional obliteration and surface-filling properties, effectively masking substrate color variations and minor surface irregularities. It delivers outstanding adhesion to bare wood, primed metal, and existing sound paintwork, forming a dense, uniform film that maximizes the color depth, gloss retention, and overall durability of the final topcoat.
 
Supplied in a convenient 2.5-liter tin, it provides optimal coverage and efficiency for medium-scale decorating projects, trim work, and detailed surface preparation. The solvent-borne formula delivers smooth flow and leveling for a brush-mark-free finish, excellent sag resistance on vertical trim, and robust film strength designed to withstand demanding interior and exterior environments.
