UltraStock-MR MDF is perfect for sink bases, dishwasher enclosures, and a variety of wet-area residential applications. It’s also suitable for laboratories, locker rooms, laundry areas, and cafeterias of schools, industrial facilities and other public buildings where wetness or high humidity are a factor.
Delivering improved dimensional stability and reduced thickness swell when wet, UltraStock-MR is especially valuable anywhere joints, seams and damage in laminated or finished surfaces allow moisture penetration. This includes interior window and door trim, baseboards and laminate flooring that may become wet from mopping, condensation or even foot traffic.
