Duram Universal Undercoat is a premium-quality, solvent-based intermediate coating designed to provide the ultimate bond between primers and final topcoats. Engineered with high-solids technology, it acts as a “leveling” layer that fills minor surface imperfections and provides a consistent, non-porous base for both interior and exterior paint systems.
Key Performance Features
- Superior Inter-Coat Adhesion: Formulated to stick powerfully to primers (like Wood Primer or Metal Primer) while providing the perfect “etched” surface for enamels and acrylics to grip.
- Excellent Hiding & Opacity: Provides a dense, white matte film that effectively masks dark colors or repaired areas, ensuring your topcoat color looks vibrant and uniform with fewer applications.
- Sandable Surface: Once dry, it can be lightly sanded to a glass-smooth finish, making it the secret weapon for high-end cabinetry, doors, and trim work.
- Versatile Compatibility: Can be overcoated with almost any decorative finish, including solvent-based high-gloss enamels and water-based premium acrylics.
Ideal Applications
- High-Contact Joinery: The essential middle layer for doors, window frames, skirting boards, and cupboards.
- Surface Transitions: Perfect for when you are switching from a solvent-based system to a water-based topcoat.
- Repair & Restoration: Ideal for covering patched plaster, filled wood holes, or previously painted surfaces that have been sanded back.
Product Benefits
- High-Build Filling: Helps “level out” the grain in wood or the profile of metal, resulting in a flatter, more professional final appearance.
- Alkali Resistant: Provides an extra layer of protection when used over masonry primers on exterior walls.
- Controlled Suction: Prevents the final topcoat from being “sucked into” the substrate, which preserves the intended sheen level (matte, silk, or gloss).
Pro Tip: For a “factory-finish” on wooden furniture or doors, apply the Universal Undercoat, allow it to dry completely, and then lightly sand with a fine 220-grit sandpaper before applying your Duram Gloss or NuGlo enamel.
