HOCHSTE® Dulux Primer and Undercoat for Wood, Quick Dry Water-Based Paint Prep, Interior Exterior Use, 2-in-1 Sealer & Base Coat, Improved Adhesion for Topcoats, (White, 750ml)

HOCHSTE
Why we love it
  • Saves time and effort.
  • Quick-drying for fast results.
  • Works on all wooden surfaces.
Main Highlights
  • 2-IN-1 PRIMER AND UNDERCOAT FOR FASTER PREP: This time-saving 2-in-1 formula acts as both a primer and undercoat in one easy step. It seals and prepares bare or previously painted wood for painting, eliminating the need for separate products. Ideal for interior and exterior use, it streamlines prep work and creates a solid foundation that boosts adhesion of your final topcoat, saving time, effort, and cost on decorating projects.
  • QUICK-DRYING WATER-BASED FORMULA: Designed for efficiency, this modern water-based paint dries quickly, typically recoatable within a few hours. That means faster turnaround and less waiting between coats. The low-odour formulation is ideal for indoor use, while clean-up is simple with just soap and water, no need for harsh chemicals. Perfect for DIYers or professionals seeking speed and convenience.
  • INTERIOR & EXTERIOR WOOD COMPATIBILITY: This versatile primer works equally well on indoor and outdoor wooden surfaces, including skirting boards, doors, furniture, window frames, sheds, and fences. Whether you’re tackling new timber or repainting, it delivers a consistent, durable base coat for long-lasting paint performance across a variety of woodwork applications around the home.
  • Smooth Finish with Stain-Blocking Power: Dulux Primer and Undercoat dries to a smooth, uniform finish that hides minor imperfections and enhances the look of your topcoat. It also features stain-blocking technology that helps seal tannins, resin, and knot marks, preventing them from bleeding through your paint. The result is a cleaner, brighter, more professional finish with better long-term appearance.
  • SUPERIOR ADHESION AND LONG-LASTING RESULTS: Formulated to maximise adhesion for both water-based and solvent-based topcoats, this undercoat helps prevent peeling and flaking. It strengthens the bond between the surface and paint, improving durability and resistance to wear and tear. By laying down a stable foundation, it extends the life of your final coat and keeps surfaces looking freshly painted for longer.
