Details
9mm moisture-resistant MDF is the optimal material for projects in humid environments like bathrooms, laundry rooms, and basements. It contains additives that create an internal moisture barrier, preventing the swelling and deterioration that standard MDF would experience, whilst maintaining workability.
While not completely waterproof, MDF's moisture resistance provides useful durability. It machines smoothly, accepts adhesives, and can be finished with paint colours of your choice. As an eco-friendly product made from recycled wood fibers and dust, it prevents waste.
We also offer priming on all of our moisture-resistant MDF sheets which allows you to skip the prep work and start painting right away. Just topcoat with your colour choice for professional results. With our customisable sizing and cutting services, your DIY build is easier than ever.
Applications
Moisture-resistant MDF is well-suited for use in humid areas of homes and businesses like bathrooms, kitchens, and storage rooms. The 9mm thickness provides good versatility for projects that need greater water resistance compared to standard MDF.
Some examples of applications for precut 9mm moisture-resistant MDF sheets:
- Bathroom storage and cabinetry, like under sink cabinets or bathroom wall shelving.
- Kitchen cabinetry backing and shelving. Can be used behind sinks and appliances that generate moisture.
- Windowsills and frames in humid aeras. MR MDF holds up much better than regular MDF sheets.
- Arts and crafts - Moisture Resistant MDF can be used as a canvas for painting, or cut pieces for woodworking projects as it is less likely to warp.
- Accent walls - We use 9mm moisture-resistant MDF as an option for our bathroom shaker panelling kits.
- Bar and shop fitting projects where moisture is a concern.
We also offer fire-rated MDF, melamine MDF and veneered MDF sheets.
Please note that although moisture-resistant MDF is suitable for humid environments, it is not suitable for external applications.

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.
