Moisture-resistant MDF

Georgia-Pacific's UltraStock MR MDF is engineered to resist elevated moisture and humidity. With the same physical characteristics and workability as premium panels, UltraStock MR meets the thickness swell and bond integrity criteria required for the MR 50 designation. UltraStock MR can be used for sink bases, dishwasher enclosures, laboratories, laundry areas, or in any area where moisture or high humidity are factors.
