| Standard MDF | Fine wood fibres bonded into a smooth, uniform panel. | Painted cabinet fronts, wall panels, shelving, and interior decorative details. | Generally intended for dry interior use; unsealed edges can absorb moisture and swell. | Smooth face takes paint well after suitable preparation. Cut edges usually need sealing and finishing. | Confirm the panel can carry the expected load and that its weight is suitable for the installation. |
| Moisture-resistant MDF | MDF made with moisture-resistant properties; specifications vary by product and application. | Interior joinery in areas with occasional humidity, such as some kitchens and bathrooms. | More suitable than standard MDF for humid conditions, but it is not waterproof and should not be left exposed to standing water. | Seal cut edges and finish all exposed surfaces in line with the product instructions. | Check the stated moisture-use classification and whether the location requires a waterproof material instead. |
| Plywood | Layers of wood veneer bonded with adjacent grain directions typically arranged at right angles. | Cabinet carcasses, furniture, shelving, and projects needing a strong panel for its weight. | Moisture performance depends on the panel grade, adhesive, and exposure; not all plywood is suitable for wet conditions. | Can be painted, clear-finished, or faced. Visible veneer edges may be left exposed or covered with edge banding. | Check veneer grade, panel thickness, bonding classification, and support spacing for the intended use. |
| Particleboard | Wood particles bonded with resin and pressed into a panel. | Cost-conscious furniture, cabinet components, and panels that will receive a decorative surface. | Standard grades are generally for dry interior use; moisture can cause swelling, especially at exposed edges. | Often used with a laminate, veneer, or other surface layer. Cover exposed edges to protect the core and improve appearance. | Check screw-holding needs, panel support, and the expected load before using it for shelves or fittings. |
| Melamine-faced particleboard | Particleboard with a factory-applied decorative resin-impregnated paper surface. | Wardrobes, cabinet interiors, office furniture, and shelving in dry interior spaces. | The surface is easy to wipe, but exposed joints and edges can allow moisture to reach the particleboard core. | Available in coordinated colors and patterns; cut edges usually require matching edge banding. | Assess scratch and heat exposure, edge protection, and whether the design needs a different surface or core. |
| High-pressure-laminate-faced panel | A panel substrate, such as particleboard or MDF, faced with high-pressure laminate (HPL). | Frequently used interior surfaces that need a durable decorative finish, including counters, worktops, and furniture. | The laminate face resists everyday surface wear, but water can still damage an unsuitable substrate through seams or edges. | Specify the laminate finish and substrate separately. Seal joints and finish edges for the exposure and appearance required. | Check impact, heat, cleaning, and moisture requirements, along with the substrate’s suitability for the location. |
