Q: What is Moisture Resistant MDF?

Moisture resistant MDF, also known as MR MDF, is a type of MDF (Medium Density Fibreboard) that has been specially formulated to have enhanced resistance to moisture and humidity. It is produced in the same way as Standard MDF, wax and resins etc however the resins (the primary bonding agent) are resistant to moisture.

Q: Why is Moisture Resistant MDF Green?

Moisture resistant MDF is dyed green to indicate that it is moisture resistant. Fire Rated MDF contains a red dye and standard MDF is contains no dye and is the same colour throughout. The depth of colour and the fact that some MR MDFs have a brown core between two layers of green, has no corelation to the degree of moisture resistance.

Q: Where can Moisture Resistant MDF be used?

Moisture resistant MDF is designed for use in higher moisture prone areas, such as kitchens and bathrooms. It’s also the product of choice for MDF skirting boards due to their proximity to hard floor surfaces (areas of mopping) and exposed brickwork in older houses. Whilst MR MDF is resistant to moisture, we would strongly advise that product is at least primed on the non-visible edges and sides for added protection.

Examples of the latter would include showers panels and kitchen splashbacks. If you do want to use require MDF for outdoor projects, or areas that regularly come into contact with water, we would recommend MEDITE Tricoya Extreme.
