Moisture-resistant MDF is not a fully waterproof material- it cannot be submerged in water or used in areas where it would get very wet, like outside in the rain for example. Moisture-resistant (MR) MDF is designed to function in humid areas where moisture is present in the air without 'splitting' or 'flaring up

Moisture Resistant MDF is a durable and versatile material that is specifically designed to withstand moisture and humidity. Made from wood fibers that have been combined with a special water-resistant resin, Moisture Resistant MDF is a dense and uniform board that is perfect for use in high-humidity areas such as bathrooms and kitchens.

Moisture Resistant MDF offers the same smooth, even surface as regular MDF. The water-resistant resin used in Moisture Resistant MDF also ensures that the board maintains its shape and strength even when exposed to moisture. This makes MR MDF a reliable and consistent material that is perfect for use in furniture manufacturing, cabinetry, and joinery.
