The Macpherson Acrylic Primer Undercoat White 1L is a high-performance, water-based primer and undercoat formulated for interior wood, plaster, brickwork, and dry lining surfaces. Widely specified by trade professionals and decorators, it serves as a fast-drying, dual-purpose preparation coating designed to seal porous substrates and create a smooth, uniform foundation for decorative topcoats.
 
Formulated with advanced acrylic resins, this primer provides excellent adhesion to new or previously painted surfaces while effectively blocking suction on absorbent materials. Its quick-drying formula allows for rapid recoating in as little as two hours, enabling decorators to apply undercoats or topcoats on the same day and significantly speeding up job completion times.
 
Supplied in a convenient 1-liter tin, it is ideal for small joinery jobs, touch-ups, and detail priming work. The low-odor, low-VOC formulation makes it well-suited for occupied indoor spaces, while its smooth flow and easy water clean-up ensure an efficient, clean application with both brush and roller.
