Paint Grade MDF for the finish you have in mind.

Select the substrate for the component you will paint

A painted furniture range begins before the colour is applied. The board, visible faces and machined details need to work with the finish your workshop wants to make. CUZI MDF manufactures MDF in Shuyang, Jiangsu, China and supplies Paint Grade MDF for cabinet doors, drawer fronts, furniture components and protected-interior panels. Bring us the component and coating plan so we can agree the input board, supplied preparation and representative sample together.

Our input MDF range is 2–35 mm, with the listed thickness-based density schedule and six full-sheet formats. Choose thickness around the finished component's dimensions, support, fixings and the material left after routing. Standard board is intended for protected dry interiors. MR MDF or HMR inputs can be selected for the appropriate humid-room construction, with suitable finish, protected cuts and the relevant product information.

These descriptions can overlap on a particular board. Compare the actual material and preparation in the quotation: grade, density, thickness, sanding condition and finish response. The Paint Grade name describes the intended selection and use; a specific density, sanding grit or primer is recorded separately. Raw MDF covers the broad unfinished-board range and Sanded MDF explains the supplied face preparation. This page connects those inputs to painted furniture manufacture.

Choose the supplied condition by the work included

Tell us which steps our factory should complete and which your finishing team will handle. Sanded MDF arrives as an uncoated substrate. Machined raw components add the agreed cutting, drilling, routing and edge preparation. Primed or completed painted supply is recorded as a separate scope when requested, with the actual products and covered surfaces agreed in the quotation.

State whether dimensions and tolerances refer to the MDF part before coating or the finished component. Include clearances where coating builds on mating edges, hinge details or handle holes. The input board's nominal thickness tolerance is ±0.1 mm; machined dimensions and coated thickness have their own measuring and acceptance agreement.

For primer supply, send the product reference and current technical instructions for the topcoat you plan to use. We agree the primer, preparation and delivery condition against that system. Your actual trial establishes compatibility and appearance. A colour code is useful for enquiry; the retained physical finished sample establishes the colour, gloss and surface reference for repeat supply.

Prepare the flat face, cut edge and groove together

A smooth board face is one part of a painted component. Cutting exposes the board edge; routing creates groove floors, sidewalls and corners with a different surface condition. Include all of these in the sample so the preparation and coating are checked where the furniture will show them. Clean machining, profile-preserving sanding, dust removal and the compatible sealer/primer sequence are planned for each surface.

The worked PA01 specimen in the drawing is a 300 × 200 mm blank of nominal 18 mm MDF. Its front has a round-ended groove with overall X limits 50–250, centreline Y = 100, width 10 mm and depth 4 mm. The front-view origin is the bottom-left corner; X increases to the right and Y upwards. The nominal MDF below the groove is 18 − 4 = 14 mm. The drawing identifies A, the flat face; B, an exposed cut edge; and C, the groove floor and walls.

This geometry is a sample-plan example. Select the actual trial dimensions and profile around your component, including any narrow detail, recess or inside corner it needs. Check the actual thickness and machining depth before recording the remaining section. Both faces, outside edges and any hardware openings receive the preparation and coverage specified for the finished part.

Use the PA01 geometry at three checkpoints: the prepared MDF, the sealer/primer stage and the completed topcoat after its specified cure. Matched specimens from the same board specification help compare checkpoints, while an identified component carried through the full sequence shows the complete process. The diagram uses schematic colours to identify stages; the real coating determines the actual appearance.

The European Panel Federation's edge-finishing guidance discusses edge preparation and a compatible sealer/finish sequence. Its profile-sanding guidance connects smoothing to retaining the intended profile detail. Your coating supplier's current instructions and the representative trial establish the products, abrasives and process used in production. The MDF edge preparation guide expands the face, edge and profile checks.

Establish a coating sequence your workshop can repeat

Record the actual sealer, primer and topcoat references together. Add application method, preparation, mixing where applicable, coat quantity or film-build requirement, application conditions, drying/cure instructions and the next-stage window from the coating supplier. These inputs describe your production system. A named generic primer or a universal sanding sequence leaves important details to be established on the actual part.

Follow the supplier's instructions for the actual coating system and equipment. After the specified cure, compare coverage, raised fibres, sanding or tool marks, corners and groove detail on the representative component. Verify any requested adhesion, resistance or other performance through the agreed method and product scope. Adjust the preparation or process as needed, then keep the updated record with the accepted trial.

Matt and high-gloss finishes have different appearance targets. Agree lighting, viewing distance and angle, colour reference, gloss reference and acceptable variation for the furniture range. A high-gloss trial makes the face and edge preparation easier to assess under the agreed light. How to Choose MDF for Painting discusses substrate selection and coating trials; our product quotation identifies the actual board and work our factory will supply.

Keep a finished sample for repeat orders

Identify the sample with its board specification, batch or input reference, part ID and drawing revision. Keep the coating products and preparation/application record with it. The table below is a check plan for actual observations and agreed tests. It describes what to record when the trial is made; the schematic drawing supplies the example geometry.

Appearance comparison and a performance test answer different purchasing questions. The retained trial establishes the visual reference. Emission documents follow the specified method and MDF/product scope; fire, moisture or coating-resistance requirements follow the relevant finished construction and test. List the destination and actual requirements so our team can confirm the available documents for your supply.

A flat colour swatch is useful for colour selection. A representative machined and finished component adds the edge, profile and fitting information needed for manufacture. For cabinet fronts, our Routed MDF Cabinet Doors page connects the front and reverse drawings, hardware and paired-door list. CNC MDF Processing covers general drawing-defined parts. Keep confirmed drawing and trial changes together before repeat production.

Plan the quotation, packing and repeat supply

Start with the component you make, thickness, sizes, quantities and destination. Add the core grade and emission requirement, part drawings, supplied condition, coating plan and sample you want to try. FOB China price: US$157–258/m³ for Paint Grade MDF. Your written quote identifies the selected MDF, quantity and price basis, with machining, priming, completed coating and packing recorded as the work included or separately charged for your order.

We reply within 12 hours. Samples are free across our full range and generally in stock. You cover the courier cost, which can be credited against a formal order. For a prepared or coated specimen, we confirm the actual geometry, supplied stage, preparation, dispatch and estimated transit time for your address. This helps your team plan the trial and its next production step.

Normal MOQ is 1 × 20'GP per specification. MDF board production capacity is 500 m³ per day across the factory; machining and coating output follow the actual operations. Normal production lead time is 3–10 days after specification and commercial confirmation, with any sample, machining and agreed coating stages scheduled in the quotation. Your quote includes price/currency, packing, FOB Qingdao or FOB Lianyungang, T/T or LC terms and validity. Third-party inspection is supported. Shipments use Lianyungang or Qingdao, with loading based on dimensions, density and packing.

Keep uncoated boards and parts flat, dry and clean through handling. For primed or finished parts, follow the agreed cure and handling conditions, with clean suitable separators, supported packs and face/edge protection. Part labels identify the drawing revision and supplied stage. On repeat orders, retain the material and finish reference, and identify changes to the board, profile, primer, topcoat, application or pack contact materials so the new batch follows the updated specification.
