The Crown Trade Fastflow Quick Dry Primer Undercoat White 2.5L is a high-performance, water-based primer and undercoat formulated for use on both interior and exterior timber and correctly prepared metalwork. Widely specified by professional decorators, contractors, and maintenance teams, it is designed to prepare surfaces for subsequent water-based or traditional solvent-based topcoats.
 
Formulated with advanced Fastflow technology, this dual-purpose primer-undercoat utilizes innovative hybrid water-based resins to deliver the flow, leveling, and opacity characteristics traditional to solvent-based products. It seals porous wood, provides exceptional adhesion on timber and suitably primed metal, and bridges surface minor irregularities to ensure a smooth, uniform base for high-gloss or satin finishes.
 
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 low-odor, low-VOC formula dries rapidly to allow recoating in just two hours, enabling multi-coat application in a single day, while tools can be easily cleaned with clean water.
