Understanding MDF and melamine
What is MDF?
Definition and characteristics: MDF (medium-density fiberboard) is an engineered wood product made by:
- Breaking down hardwood or softwood residuals into wood fibers
- Combining them with wax and a resin binder
- Forming panels by applying pressure at high pressure and temperature.
It has a smooth, consistent, dense, strong, and flat surface.
Common uses in cabinetry: MDF is widely used in cabinetry due to its smooth surface, which is ideal for painting or veneering. It can be easily machined into intricate shapes, making it suitable for detailed cabinet doors and moldings.
What is melamine?
- Definition and properties: Melamine is a plastic resin used as a surface coating for particleboard, MDF, and other materials. It is known for its durability and resistance to stains, scratches, and heat. Melamine also comes in various colors and finishes.
- Why it’s used on MDF cabinets: Melamine is often applied to MDF cabinets to enhance their durability and aesthetic appeal. It provides a hard, smooth surface that is easy to clean and maintain, and it can mimic the look of more expensive materials like wood or stone.

Necessary preparations for painting
Importance of proper surface preparation:
- Cleaning: Thoroughly clean the cabinets to remove grease, dust, and dirt, which can interfere with paint adhesion.
- Sanding: Lightly sand the melamine surface to create a rough texture that helps the primer and paint adhere better.
- Priming: Use a high-quality primer specifically designed for melamine or laminate surfaces to ensure proper paint adhesion.
Tools and materials needed:
- Cleaning supplies: Degreaser or mild detergent, water, and cloths.
- Sandpaper: Fine-grit sandpaper (e.g., 220-grit) for lightly sanding the surface.
- Primer: A primer suitable for glossy surfaces or specifically for melamine.
- Paint: High-quality acrylic latex or oil-based paint designed for cabinetry.
- Brushes and rollers: High-density foam rollers and synthetic bristle brushes for smooth application.
- Painter’s tape and drop cloths: To protect areas around the cabinets and ensure clean edges.
- Protective gear: Gloves, mask, and eye protection to ensure safety during the preparation and painting process.
Preparing MDF (melamine) cabinets for painting
MDF (Melamine) Cabinets for Painting
1. Cleaning the surface
- Removing dirt, grease, and residue: Clean the cabinets thoroughly to remove dirt, grease, and residue. This ensures a smooth surface for painting.
- Recommended cleaning solutions: Use a mild detergent or a mixture of water and vinegar. A degreaser might be necessary for more stubborn grease.
2. Sanding the cabinets
- Importance of sanding for adhesion: Sanding is crucial as it roughens the smooth melamine surface, allowing the primer and paint to adhere better.
- Techniques and tools for effective sanding: Use 120- to 220-grit sandpaper. An orbital sander can speed up the process, but hand sanding works well for detailed areas.
3. Priming the surface
- Choosing the correct primer for MDF and Melamine: Use a high-quality bonding primer specifically designed for slick surfaces like melamine. Shellac-based or urethane-based primers are excellent choices.
- Application tips for best results: Apply the primer in thin, even coats using a high-density foam roller or a high-quality brush. Allow adequate drying time between coats.
These steps ensure a durable and attractive finish on MDF (melamine) cabinets.
Painting MDF (melamine) cabinets
1. Choosing the right paint
- Types of paint: Use a high-quality primer designed for melamine or MDF, followed by either acrylic or oil-based paint. Specialty melamine paints are also available.
- Benefits: High-quality paints offer better adhesion, durability, and a smoother finish, which is crucial for melamine surfaces.
2. Application techniques
- Tools: Brushes, rollers, and sprayers can all be used. Sprayers typically provide the smoothest finish, but brushes and rollers are more accessible.
- Tips: Ensure even application by using long, consistent strokes. Sand lightly between coats to maintain a smooth surface.
3. Drying and curing
- Drying time: Allow each coat to dry thoroughly before applying the next. Follow the paint manufacturer’s guidelines for drying times.
- Curing: Proper curing is essential for durability. Depending on the paint type, the process can take several days to weeks. Avoid heavy use until fully cured.
4. Applying multiple coats
- When and why: Multiple coats are often necessary for even coverage and durability. At least two coats are recommended.
- Techniques: Apply thin, even layers to avoid streaks and drips. Sand lightly between coats to ensure smooth layering.
Finishing touches
Here are some brief points on finishing touches after painting melamine (MDF) cabinets:
Sealing the paint
- Benefits of using a topcoat or sealant:
- Provides extra protection against scratches, moisture, and wear.
- Enhances the durability of the paint, prolonging the finish.
- Can add a desired sheen or matte effect, enhancing the aesthetic appeal.
- Types of finishes and their effects:
- Matte finish: Offers a non-reflective, smooth appearance, hiding imperfections well.
- Satin finish: Slightly reflective, providing a soft sheen and easy-to-clean surface.
- Gloss finish: Highly reflective, giving a shiny, modern look, but can highlight imperfections.
Reattaching the hardware
- Properly reattaching handles, knobs, and hinges:
- Ensure all hardware is clean and free of old paint or debris.
- Use a screwdriver to carefully reattach handles, knobs, and hinges, ensuring they are aligned correctly.
- Tighten screws just enough to hold the hardware securely without over-tightening, which can damage the paint or the MDF.
- Tips for avoiding damage to the new paint:
- Allow the paint to cure fully before reattaching hardware, typically a few days to a week.
- Use painter’s tape around the hardware placement areas to protect the paint from scratches.
- Handle the cabinets gently and avoid heavy pressure when reattaching hardware.
