Melamine Plywood Advantages and Disadvantages

Also known as white melamine-faced plywood, it is a type of engineered wood product widely used in furniture making, cabinetry, and interior design. It is a relative newcomer to the plywood family. It is made of particle board with a melamine coating on the face side of plywood.

White melamine plywood is extensively used in manufacturing kitchens, baths, and furniture where a solid white surface rather than wood grain is desired. Melamine is an organic compound that most people consider an inexpensive plastic.

Advantages:

1. Aesthetic Appeal: Comes in various colors, patterns, and finishes, allowing for versatile design options. It can mimic the look of natural wood, stone, or other materials at a fraction of the cost.
2. Durability: This kind of plywood is highly durable and resistant to scratches, stains, and moisture compared to standard plywood. This makes it suitable for use in areas prone to moisture exposure, such as kitchens and bathrooms.
3. Easy Maintenance: It is easy to clean and maintain. Spills and stains can be wiped away with a damp cloth, and the surface is less prone to damage from everyday use.
4. Consistency: It is manufactured in a controlled environment, ensuring consistency in thickness, size, and quality. This consistency makes it easier to work with, and results in a more uniform finished product.
5. Cost-Effective: It is generally more affordable while providing a stylish and durable finish.

Disadvantages:

1. Susceptibility to Heat and Scratches: It is susceptible to sharp objects and high-heat damage. Scratches and chips may occur with heavy use or if not handled carefully.
2. Limited Repair Options: It cannot be sanded down and refinished if scratched or damaged. Once the surface is compromised, repair options are limited, often requiring a full replacement of the affected panel.
3. Limited Structural Strength: It may not offer the same structural strength as solid wood or other engineered wood products, like plywood with a hardwood veneer.
4. Formaldehyde Emissions: Some products may emit formaldehyde, a volatile organic compound (VOC), especially if they are of lower quality or not manufactured to strict environmental standards. This emission can contribute to indoor air pollution and pose health risks, particularly in poorly ventilated spaces.
5. Not Suitable for Exterior Use: Designed for interior applications only and should not be used in outdoor settings or areas exposed to direct sunlight and moisture, as it can degrade quickly under such conditions.

More About The Subject

When turned into melamine plywood, the melamine provides a waterproof surface that can be easily cleaned and protects the board core from water damage and staining. However, melamine panels are not fully waterproof, as only the surface is covered with melamine.

Even when iron-on melamine edging is applied, water can seep at the corners and through the back, causing the particle board to delaminate. Once the process is started, it accelerates as the board swells and more end grain becomes exposed.

Melamine plywood panels can be considered similar to those used to manufacture inexpensive furniture that IKEA makes. However, the melamine coating is more durable than the vinyl coating used on those panels.

Melamine is made of the same rosin as Formica and other laminates used on kitchen countertops. It is considerably more scratch, heat, and wear resistant than that vinyl coating.

Working with Melamine

It is available from lumberyards and building material centers for the do-it-yourselfer. Due to the weight, special milling techniques are required to avoid chipping the edges. Nevertheless, the lower cost, especially the finished appearance, makes it a great product for certain applications.

When cutting melamine, care must be taken to avoid chipping the edges. To avoid this, furniture and cabinet manufacturers normally use a CNC router.

We can take a page from their book using a plunge router with a narrow straight bit for cutting. Used with a straight edge, this will provide a very clean cut, albeit with a wider “saw kerf.”

It is a good idea to score the melamine coating with a utility knife and cut through it before cutting the particleboard beneath.

Melamine plywood can also be cut with a circular saw or table saw. Before cutting, it is always a good idea to score through the melamine coating itself. A sharp, fine-toothed carbide blade should be used.

Drilling holes in melamine can also be problematic, as a normal drill bit will tend to chip the edges of the holes. The plunge router can also solve this problem, making holes into or through the melamine. The only problem is finding straight carbide router bits of the size needed. The router can also be used with a chamfer bit to countersink those holes if screws are being used for fastening the panels.

Fasteners and Melamine

Because melamine is a particle board, it doesn’t provide as much hold with either nails or screws as hardwood plywood does. Brad nails from a pneumatic nailer should not be used on melamine plywood except in non-structural places, such as nailing the back panel onto a cabinet while the glue dries. Panels connected with wood glue and nails cannot be counted on to hold together, as the particular board core does not provide enough grip on the nails.

The screw can be used as long as the proper precautions are taken. Coarse-thread screws, such as coarse-threaded drywall screws, are best.

A clearance hole should be drilled through the panel being fastened, with a smaller pilot hole in the panel it is being fastened to. If the screw will be going into the edge of a piece, it should be kept at least 2-1/2” from the corner. These screw holes should be countersunk, or a face washer should be used with the screw.

These fasteners have been developed especially for particle boards, making them ideal for use with melamine plywood. While these connectors are more expensive, the longer life they give the finished product makes them worth investing in.

Melamine Versus Plywood

Kitchen cabinets and furniture are both made out of melamine plywood and hardwood plywood. Both materials have their proponents, mostly the companies that choose to use them. Yet the two materials generally provide quite different visual finishes, which become the major deciding point when choosing between the two.

Also, it is not limited to white, although that is the most common color available when purchasing it in the lumberyard.

Even though melamine plywood is available with a printed hardwood grain, hardwood plywood is preferred in high-grade cabinet construction. While hardwood plywood is considerably more expensive, the visual difference between the two is considerable. No artificial plywood grain looks quite like the real thing. People who want the beauty of wood can quickly notice the difference.

Of the two, plywood is lighter and stronger against breakage. Plywood is also easier to fasten, as the wood grain holds both nails and threaded fasteners well.

Both materials are likely to include some formaldehyde, as it is used in the adhesives that are part of the manufacture of both plywood products. But the formaldehyde will flash off quickly, limiting any risk of contact unless the adhesives begin to dissolve.

Conclusion

Melamine plywood offers many benefits in aesthetics, durability, and affordability. It’s essential to consider its limitations and suitability for specific applications before choosing a project.
