Are MDF Boards Waterproof?

It’s easy to lose sight of things in the furniture sector because of the constant innovation. New construction methods and inventive possibilities of timber have emerged quickly in recent years, especially as concerns about sustainability and the carbon footprint of buildings have grown.

In this blog, we’ll answer all the questions you might have about a comparatively new entrant in the wood panel industry 一 The MDF board.

If you haven’t heard of it, fret not. By the end of this article, you’ll know everything there is to know about these boards. So let’s start with the basics. 

What is an MDF board? 

MDF boards, also known as Medium Density Fibreboards, were developed as a substitute for solid wood by utilising the huge waste of wood chips and sawdust produced by lumber mills. 

The process of making MDF boards involves using a defibrator(thermomechanical pulping refiner) to break down hardwood or softwood residual chips into wood fibres. These wood fibres are then combined with wax and resin binders to form panels under high pressure and temperature.

Are MDF boards waterproof?

MDF boards are water-resistant to a certain level. But it can get weathered after prolonged exposure making it more vulnerable to moisture. However, there are products on the market that are more resistant to moisture and even fire (exterior grade and interior grade). So be on the lookout for the right MDF board specification you require. 

Is the MDF board termite proof?

Chipboard, MDF, laminates, and other wood combined with glue are not consumed by termites. But they may pass through these materials on their way to the “good stuff,” such as your timber infrastructure and built-in framework. However, this can be prevented by chemically treating and sealing them.

Is MDF board better than plywood? 

Though you see both MDF boards and plywood used indoors, they cannot be used interchangeably. There are certain pros and cons of each board you need to consider before using them during construction. 

For example, since MDF does not handle moisture well, you cannot use them in areas that are exposed to constant moisture. But the boiling waterproof plywood is much stronger and can handle water exposure. 

What is MDF board used for?

The applications of MDF boards are numerous. They are commonly used in  – 

  • Wall panels 
  • Floorings

Are MDF boards with laminate available? 

Yes, an additional layer of laminate coating can be added to the fibreboard surface to make it scratch-resistant and highly durable. 

The MDF board can also be veneered, lacquered, painted, or coated with PVC to fit your requirements. They can be made to look just like wood. This way, you have a sustainable and affordable alternative to use for your interior decor and/or furniture. 

In conclusion, the MDF board is a pretty good alternative for natural wood. It’s made of high levels of waste produced by the lumber mills, making it eco-friendly. A lot of people still have reservations about it due to the use of formaldehyde in its production. This concern can be put to ease by following the necessary precautions.
