Moisture resistant (MR) MDF is manufactured utilising resins that are appropriate for use in areas of high humidity such as kitchens, laundry rooms and bathrooms. MR MDF is NOT suitable for use in wet conditions,
as it will swell in the same way as standard MDF
(albeit not as much). Most (but not all) MR MDF is manufactured with
the inclusion of a green dye which is for identification purposes only.
