What is MDF?

MDF full form is Medium Density Fibreboard. MDF is made when the wood fibre sheets are amalgamated with thermosetting resins under high heat and pressure, resulting in a board with a consistent and close-packed fibre distribution. This engineered wood has now become more reliable and affordable because of rapid technological and industrial advancements.

MDF is becoming one of the most used sheet materials in the construction industry. Now that we've explored what MDF board is used for, let's check some advantages of why it's a preferred choice.

Advantages of Strong Medium Density Fibreboard:

1. Cost-Effective and Easily Available:

MDF is produced in such a way that it is less expensive than genuine wood. You can acquire the look of real wood without spending much money. MDF is more affordable than plywood or any other type of wood. Also, MDF offers economic value because it is easily available and within everyone's reach to buy it at no extra expense. It is also easy to find in any specific size opposite to oak, rosewood, maple etc.

2. High-Density Material:

MDF is a precisely engineered material so there is no grain in it. It has no splintering, scorching, or tear-out when cut with a router, scroll saw, band saw, or jigsaw. Hence it is easy to cut or drill without making damage as it is not a natural product. Its great density allows the equipment to be used on it.

3. MDF is Strong:

MDF is a composite material of high quality and comprises of resins and wood fibres. To make dense and sturdy sheets, it is dried and pressed. Hence MDF, unlike wood, does not warp or crack as a result of this technique used in its production. Although it is made up of wood fibres, it can be used as a building material in the same way as plywood is used and it is also denser and stronger than particle board.

4. Stable, Durable and Sustainable:

Medium-density fibreboard is a relatively stable product that requires less fixing during the time of its existence and it is also a long-lasting product that is sturdy , durable and has a good fire resistance rating.

5. Perfect For Painting and Layering:

MDF has a smooth, paint-friendly surface without grain, texture, or knots. MDF sheets will be hefty, smooth, and even, with a flat, paintable, or sealable surface. Unlike natural wood, MDF can be stained or painted easily. MDF panels can also be covered in laminates or wood veneers to give them a real-wood alike look. As a result, when it comes to appearance, MDF is the greatest replacement for real wood.

6. The Best Material For Cabinetry:

Engineered wood has undeniable advantages for cabinet doors because of its flexibility. Cabinets can be composed of fibreboard and then finished with solid wood laminate on the top. Several varieties of MDF are moisture-resistant, which is important for kitchen and bathroom furniture.

7. Environment Friendly:

MDF is produced in such a way that decreases virgin wood material costs. MDF is made entirely of plantation wood, ensuring that no trees are cut down in the process, making it environment friendly.

8. Say No To Termites and Insects:

MDF is a form of engineered wood that is made by gluing layers of wood fibre together and the glue used to make MDF can also help as a termite inhibitor. As a result, we can say that MDF is resistant to termites, borer and fungus.

9. LOW VOC and Formaldehyde Emission:

MDF is completely safe for on-site and off-site use as they are eco-friendly, emitting very little formaldehyde. Secondly, MDF is neutral enough not to release any unwelcomed VOC's (Volatile Organic Compounds) at room temperature in your house.

Finishing Up:

In this blog, we have seen all the possible advantages of the MDF board. The aforementioned benefits may explain why MDF board or sheets are becoming more popular. And it is always vital to check out the core factors of the material before deciding to use it for your construction or decorative purposes.

MDF is a popular alternative to natural wood utilised in various settings.

MDF is denser than plywood, another synthetic wood, and a relatively cheaper option.

One major problem with MDF is its low tolerance to humid and moist conditions. It tends to absorb water which destroys the material.

In this article, we'll take an in-depth look at MDF and outline steps to waterproof it effectively.

What is MDF?

Medium-density fibreboard (MDF) is a type of engineered wood.

It consists of wood by-products, shavings, sawdust, and other residual fibres.

The wood by-products are dried and grounded into powder.

It is then mixed with wax and resin and subjected to a high-pressure press into flat panels by mechanical means.

There are various types of MDF, including:

• Standard MDF
• Ultralight MDF
• Moisture Resistant MDF
• Fire Retardant MDF
• Exterior Grade MDF
• Valchromat MDF
• Melamine Faced MDF

Is Standard MDF Waterproof?

Standard MDF is not waterproof, and only short term exposure to water will damage it because it will typically be absorbed.

This exposure will cause the MDF to swell, rendering it useless.

MDF is made of wood fibre bound together by resin adhesive, making it moisture resistant.

But it is not waterproof, and little cuts or prolonged exposure to water will damage it.

For this reason, standard MDF is suited for indoor use, such as for cabinets, shelves, and other objects in places with low moisture or humidity.

Remember that waterproofing your MDF does not offer protection from prolonged exposure to water however.

Benefits of Using MDF

Besides the fact that MDF is less expensive than plywood, there are other benefits to using MDF in your home.

They include:

• MDF's density and shape make it solid and less likely to warp out of shape.
• MDF is easy to drill and cut without damaging the surface. Its durability is due to its composition.
• It works well with carpentry adhesives and polyurethane glues. In addition, MDF glues easily to most materials.
• MDF can easily be fastened together with screws and nails without damaging the surface.
• It is easy to paint.
• MDF can easily be cut and designed to create decorative door panels and other features around the home.
• MDF is a perfect substitute for plastic laminate and veneer as it has the appearance of real wood without the cost.
• MDF is resistant to termites due to the chemicals treatments (such Boric acid, Borax, and urea-formaldehyde) used when manufacturing it.
• MDF is eco-friendly and can be recycled.

Making MDF Waterproof

There are two methods to waterproof MDF.

You can opt for using manufactured Moisture Resistant MDF, which is a little more expensive than standard MDF.

Or you can paint your MDF with moisture-resistant wood sealant or varnish.

Contact us to discuss your requirements of mdf waterproof. Our experienced sales team can help you identify the options that best suit your needs.

Painting your MDF will require you to apply several coats of wood sealant and waterproof paint to its surface.

Either option provides the MDF with protection against moisture.

However, prolonged exposure to water will damage the MDF regardless of the protection provided.

Tools Required

• A quality wood sealant or varnish
• Paintbrush
• Sandpaper
• Roller tray liner
• Roller tray
• ' inch Roller cover

Step One: Prepare Tools

Fix your '-inch roller cover into its roller.

A '-inch roller is recommended to maximise the spread of the paint on the MDF board.

Place a roller tray liner inside the roller tray.

Step Two: Apply Sealer

Apply the sealer to the edges using the paintbrush.

Ensure that all edges are properly covered, and that there's no drips.

Proceed to apply the sealant to the surface.

We recommend applying at least two coats to the MDF surface.

Let it dry for at least 5 hours.

Clean the surface of the MDF and prepare tools for painting.

There are different sealants for waterproofing.

The most popular method, and the one recommended is primer sealant.

Other methods of sealant include:

Bondo technique

This method involves applying the Bondo filler across the edges and surface of the MDF.

This provides an adequate seal.

The only drawback is Bondo dries easily, and may not be suitable for larger jobs.

Water & glue technique

The technique is cheap and very effective.

It involves mixing water and glue in a container before applying it to the MDF as a sealer.

The only setback of this method is that you may need to add another coat after it has dried, as it's not always visible during application.

Glazing putty technique

Glazing putty is a great sealer and easy to sand after painting.

It's not as hard as the Bondo substance however.

Primer technique

Primers are the recommended sealer as they help bond the waterproof coat to the MDF.

Step Three: Apply Moisture-Resistant Paint

The next step is applying the first moisture-resistant paint coat on both sides.

You can sandpaper the edges to ensure a smooth feel.

Once the coat is dried, it is recommended to apply a second coat to ensure the MDF is properly covered.

Paint the edges of the MDF boards too.

Leave the paint to dry for at least two days.

Conclusion

As mentioned above, MDF is a solid alternative to natural wood.

It is also your best bet if you want something aesthetically pleasing, yet more economical than plywood.

Remember, you don't want to expose MDF to humid or moist conditions, so you should be mindful of where you're going to use it.

There are types of MDF that can work in harsh or wet weather conditions, so you should always do your research before using this highly versatile building material.
