Duram DTM Smooth is a premium-quality, water-based acrylic coating specifically engineered for application directly onto metal surfaces. By combining the properties of a primer, undercoat, and topcoat into a single product, it offers a streamlined solution for protecting and beautifying metalwork without the need for multiple separate layers.
Key Performance Features
- Direct-to-Metal Technology: Formulated with specialized adhesion promoters that allow it to bond powerfully to various metal substrates without a dedicated primer.
- Advanced Corrosion Protection: Contains “active” anti-corrosive additives that create a chemical barrier against rust and oxidation, even in coastal environments.
- Superior UV Resistance: Designed to withstand intense South African sunlight, ensuring the smooth, mid-sheen finish doesn’t chalk, fade, or peel over time.
- Rapid-Drying Efficiency: Water-based formula that is touch-dry in just 30 to 60 minutes, allowing you to apply a second coat and finish your project in a single morning.
Ideal Applications
- Gates & Fencing: Perfect for palisade fencing, driveway gates, and garden railings.
- Window & Door Frames: Ideal for both interior and exterior steel or aluminum frames.
- Roofing Details: Excellent for downpipes, gutters, and flashings where a smooth, decorative finish is required.
- Substrates: Bonds effectively to mild steel, galvanized iron (weathered), and previously painted metal.
Product Benefits
- Low Odor & Low VOC: A safer, environmentally friendly choice for indoor and outdoor use; tools clean up easily with soapy water.
- Excellent Flow & Leveling: Specially balanced consistency that hides brush marks, resulting in a sleek, professional “smooth” appearance.
- Durable & Flexible: The coating moves with the metal during temperature changes, preventing the brittle cracking common in old-fashioned enamels.
Pro Tip: For new or “shiny” galvanized iron, it is still best practice to clean the surface with Duram NS7 Metal Etch first. For very heavy-duty industrial or highly corrosive environments, using Duram NS4 as a base will provide the ultimate “belt-and-braces” protection.
