What is 18mm Moisture Resistant MDF?
18mm Moisture Resistant MDF (Medium Density Fibreboard) is an engineered wood product specifically designed for environments where moisture exposure is a concern but full waterproofing isn’t necessary.
Enhanced with moisture-resistant resins, 18mm MR MDF supersedes the performance of standard MDF in humid spaces like kitchens, bathrooms, and laundry rooms. Although not waterproof, it’s well-suited for interior applications requiring a durable, smooth material. It can be easily cut, shaped, and finished with paint or veneer to achieve a polished look.
Where Is 18mm MR MDF Used?
- Furniture
- Bathroom and kitchen furniture
- Flooring
- Doors and window boards
- Shelving
- Skirting boards
- Cabinets
- Wall panelling
- Laundry rooms
18mm MR MDF Sheet Benefits
- Ideal in applications in which humidity can fluctuate
- High internal bond strength
- Popular in the joinery industry
- Easily shaped with machine tools and hand tools
- Easy to handle
- Interior use only
- Suitable for a wide range of machining and surface finishes
- The panel conforms to the latest European low emission standards ‘E1'
- Easy to sand down for a smooth finish (which also prevents harmful fibres from being released)
Do You Need To Prime 18mm Moisture Resistant MDF ?
When it comes to painting MDF, be it moisture resistant or standard, it will need to be primed before application. The primer acts as a sealant, in this case, ensuring that the topcoat of paint does not bleed into the MDF.
Is All 18mm MR MDF Green?
Here in the UK, smaller MR MDF boards are typically green in colour, however, this is purely for identification purposes and has no ties to the actual moisture resistance of the boards.
There are MR MDF boards sold that are untinted and brown in colour, appearing very similar to standard MDF.
Should you be wondering how to identify the MR properties in boards such as these, simply refer to the manufacturer's technical specification sheet and keep an eye out for standards related to MDF: EN622-5: 2009 (which covers moisture resistance).
How is 18mm Moisture Resistant MDF Made?
The manufacturing process for MDF (short for Medium Density Fibreboard) sees wood fibres (wood chippings, recycled offcuts and sawdust) combined with resins and waxes cooked to a high temperature and pressed under high pressure to form sturdy uniform panels.
18mm MR MDF owes its moisture resistance to the moisture-repellent resin used to bond the wood fibres together.
The manufacturing process eliminates knots, air pockets, and grain issues from the MDF boards, ensuring a uniform, defect-free precision finish.
18mm MR MDF Weight
Each 18mm MR MDF sheet weighs a sturdy 35kg, providing the perfect balance between durability and manageability. This weight ensures the fibreboard's resilience while remaining easy to handle and transport.
