Moisture-resistant MDF (MR MDF) brings the versatility of medium-density fiberboard to damp and humid environments. Advanced binders and additives are used to create an internal water barrier that makes MR MDF ideal for use in damp environments like bathrooms, laundry rooms, and basements where using standard MDF boards should be avoided.

Whether you're installing building cabinetry or crafting furniture, our moisture-resistant MDF has you covered. We offer these green boards in a range of thicknesses which are cut to size to suit any project. With our cutting services, we can also customise your MR MDF with drilled holes, cutouts, and rounded edges, so your DIY build is faster and easier.

Details

Our moisture-resistant MDF boards are well-suited for use in environments that are prone to humidity and high moisture levels, such as bathrooms, kitchens, or utility rooms. Water-resistant MDF is engineered with hydrophobic substances throughout the fibres that repel water and prevent moisture absorption. Waxes and resins create a water barrier within the wood fibres. This allows the MR MDF to withstand spills, splashes and high ambient humidity without swelling, rippling or loss of bond strength that occurs in regular MDF whilst retaining the smooth machinability of standard MDF sheets.

While not completely waterproof, MR MDF demonstrates significantly improved water resistance and dimensional stability in damp conditions. The enhanced moisture protection expands the possibilities for MDF in new wet applications.

With a slight green tint, MR MDF offers a smooth, consistent surface that machines and finishes beautifully. The enhanced durability retains high bond strength for overlays and laminates. Painted MR MDF achieves a flawless factory-finished look.

Our moisture-resistant MDF is also now available to be primed on one, or both sides of your sheet making our moisture-resistant MDF ideal for painting. For more information on what MDF to choose for your project, see our guide ‘Choosing the Right MDF’.

Additionally, the light and smooth surface of our moisture-resistant MDF sheets makes it easy to mark up for cutting or sanding down, and it can be cut into various shapes and forms with ease using an electric saw, router, or handsaw. Please note that when cutting MDF, appropriate protection must be worn due to the dust particles MDF can create.

Our moisture-resistant MDF is ranked with the Euroclass D Fire Rating, though if you require MDF to prevent the spread of fire, please see our flame-retardant MDF which can prevent the spread of fire by up to half an hour.

Key Features of Moisture Resistant MDF

  • Hydrophobic agents resist swelling and warping when wet
  • Maintains strength and form in humid/damp conditions
  • Minimizes moisture absorption through edges and surfaces
  • Added waxes create an internal moisture barrier
  • Prevents growth of mould, mildew and fungi
  • Ideal bonding properties for overlays and laminates
  • Hard, scratch-resistant surface stands up to wear
  • Consistent smooth face optimizes painted finishes
  • Easy to cut, drill, joint and edge using woodworking tools
  • Strong and stable; resists bowing or rippling
  • Lighter than plywood for easy handling and installation

Applications & Uses

  • Bathroom vanities and cabinets - MR MDF is ideal for bathroom cabinetry where moisture levels tend to be high. It resists swelling and damage from splashes.
  • Kitchen cabinets and shelving - For cabinet boxes, kitchen doors, and pantry shelving in kitchens where spills may occur. Provides moisture protection.
  • Splashbacks and wall panelling - Used for tub/shower surrounds, wall panels, and kitchen splashbacks.
  • Countertops - Can be used as a substrate for laminate or granite/quartz countertops.
  • Furniture - Used to construct desks table tops, shelves, and other furniture where moisture resistance is valued.
  • Garage storage and workbenches - Ideal for garage cabinetry, shelving units, and workbench tops where condensation is common.
  • Flooring underlayment - Provides a stable and moisture-resistant substrate layer for vinyl, laminate or other floating floors.
  • Restaurant and bar areas - Used for cabinets, partitions, wainscoting, and table tops in high-humidity restaurant and bar environments.
  • Signs, displays and exhibits - Improved water resistance where high humidity or outdoor exposure is expected.
  • Hotel bathrooms and cubicles - Well suited for hotel furniture that sees heavy use and potential water exposure from guests.

 

Using our cut to size 18mm moisture resistant MDF, Kanza (@handmadehome_durham on Instagram) upcycled her IKEA KALLAX. After cutting the MDF into arches, she primed and painted it with Farrow and Ball Hague Blue.

 

We collaborated with Kerry (sunnysideourourstreet on TikTok and Instagram) on her kitchen panelling project. We supplied her with Moisture Resistant MDF to update her panelling, and it is much quicker to paint than our standard MDF!

Frequently Asked Questions

What is moisture-resistant MDF?

With a slight green tint, water-resistant MDF, also known as MR MDF, contains a moisture-repellent resin that provides increased resistance to humidity. Waxes and resins create a water barrier within the wood fibres. As a result of this, our MR MDF is ideal for use in high-humidity areas or areas of high moisture.

What thickness do I need?

Thinner sheets, like 6mm and 9mm MR MDF, are good for lightweight panels, overlays and cabinet components. Medium thicknesses like 12mm and 18mm MR MDF are very versatile for furniture, cabinets, shelving and built-ins. The thickest 25mm MR MDF provides extra durability for heavy-duty furniture tops, worktops, and shelving.

Is all MDF moisture-resistant?

Not all MDF is moisture-resistant. MDF is a porous material, and moisture-resistant sheets prevent the MDF sheets from warping or being affected by moisture.

Can you paint moisture-resistant MDF?

Often chosen for its inexpensive cost to create furniture, MDF can be painted to add some character or personality to any piece.  You can find out more in our guide: How to Paint MDF

How do you waterproof MDF panels?

Moisture-resistant MDF sheets are already resistant to moist areas and humidity, however, you can improve their hydrophobia by coating them in an appropriate waterproof primer or paint.

How does MR MDF compare to plywood for moisture resistance?

Plywood uses waterproof glues but can still separate when wet. MR MDF retains its form and strength better than wood-based boards. We offer a range of marine plywood boards if MDF isn't suitable for your project.

Charged £30 for next day delivery. Arrived 3 days late. More than a month now with zero response from customer service about refunding shipping charge. Terrible company with no customer service at all.

Everything was fine about the product, but we paid extra and ordered it on an express delivery to be delivered on the Friday, then we received an email informing us it wouldn’t be delivered until the following Wednesday, which interfered with our decorating plans. We haven’t received any refund for paying extra amount
