Our Classic Composite Decking delivers the natural look of timber with the practicality of composite, at an affordable price point. Made from 60% wood fibre and 30% recycled HDPE, it offers lasting performance without the upkeep of traditional decking. Each board is reversible, with a choice of a wood-grain texture or clean grooved profile. IMPORTANT NOTE: As with all uncapped composites, Dex Classic will naturally lighten in the first few months before settling into a consistent, weathered tone. The boards remain resistant to algae, rot, splintering and warping, ensuring long-term reliability even as the colour softens. Available in five colours - Black, Brown, Natural, Grey and Teak - our classic board suits residential projects where style and value matter. Installation is simple with the hidden clip system, creating a clean finish and allowing effective drainage between boards. Boards require no staining or painting, a simple occasional clean with warm soapy water is enough to maintain their finish Board size: 148 × 25mm Warranty: 10 years Finish: Dual-sided - Woodgrain & Groove Colours: Black, Grey, Natural, Teak, Brown Material: 60% wood fibre, 30% recycled HDPE, 10% additives Installation Guidance * Allow boards to acclimatise on site for 72 hours before installation. * Do not install below 5°C. * Subframe centres: max 350mm. * Keep 15mm clearance from walls/obstacles for expansion. * Allow 8mm gap on butt joints. * Subframe must be fixed securely with expansion screws at 300–400mm spacing. * Always ensure sufficient drainage and ventilation under the deck. * Gradient: 1–1.5% away from walls for water runoff. * Use hidden clips (pre-drill with 2.5mm bit) on every joist. * Joists should be doubled up at butt joints for full support. * Angle trims should be fixed with STORMFix adhesive, not screws. Weathering & Care * Boards will naturally lighten within 12 months before stabilising. * Water marks/tannins may appear in early months - these fade with weathering. * Clean periodically with hot water and a soft brush. * Do not use bleach or harsh detergents. * Avoid direct ground contact (soil/grass) or poorly ventilated areas
