📝 Product Description
Johnstone's Trade Aqua Water Based Undercoat (Brilliant White) is an eco-friendly, low-VOC undercoat designed to prepare interior and exterior wood and metal surfaces for topcoating.
Specially formulated to offer the application and flow characteristics of a traditional solvent-based undercoat, it dries rapidly with minimal odour. It provides excellent opacity, smooth coverage, and helps maintain the high gloss or satin finish of Johnstone’s Aqua topcoats over time.
Key Features & Benefits:
Fast Drying & Low Odour: Touch dry in 1–2 hours and recoatable in 4–6 hours, letting you apply undercoat and topcoat in a single day.
Superior Flow & Coverage: Spreads smoothly like a traditional solvent-based undercoat without the strong fumes.
Versatile Surface Compatibility: Ideal under both water-based and solvent-based trim finishes (such as Aqua Gloss or Aqua Satin).
Interior & Exterior Use: Suitable for doors, skirting boards, window frames, radiators, cladding, and metal trim.
Gloss Retention: Specially formulated to maintain the depth and sheen of subsequent Aqua water-based topcoats.
Easy Clean-Up: Brushes and rollers wash out easily in warm, soapy water.
