Johnstone's Quick Dry Primer Undercoat Brilliant White 250ml

Johnstone's Quick Dry Primer Undercoat in Brilliant White delivers a rapid-setting sealing layer that blocks underlying stains and locks existing pigment in place before your final finish goes on. Specially engineered for wood and metal substrates, this 250ml formulation bridges raw material and paint with reliable adhesion. The accelerated drying chemistry cuts setup time by allowing efficient re-coating sooner, streamlining multi-day projects without extended downtime. The measured volume suits targeted repairs on doors, skirting boards, radiators, and patchwork, eliminating the waste associated with bulk tins while still providing enough coverage for medium-sized prep work. The bright white base neutralises previous colours, preventing undertones from shifting during the application of mid-tone or dark gloss topcoats. Robust binders form a tight bond on prepared surfaces, sealing the substrate so the final enamel or satin finish cures evenly and resists premature wear. This reliable base layer extends the lifespan of your paintwork by inhibiting moisture ingress and stopping surface degradation at the core. This ready-mixed undercoat supplies consistent opacity and a structurally sound foundation, making it the practical choice for decorators who need dependable preparation across domestic maintenance tasks and larger renovation sequences.
